Why choose polythene for packaging?

Polythene is produced more than any other polymer. It can be processed and reprocessed into many different products.

Polythene products are not biodegradable. Polythene is photodegradable. It will breakdown in sunlight in about 12 months.

Our stock polythene is suitable for food use.

Polyethylene plastic consists of a thermoplastic material and is used in a variety of consumer products.

Polyethylene is strong, can endure excessive temperatures, lightweight, water resistant and economical.

Polyethylene's superb moisture resistance and durability make it the ideal choice for industrial packaging supplies.

High density polyethylene (HDPE)
  • Low density polyethylene (LDPE) is more flexible and softer than high density polyethylene.
  • We offers a complete line of high density polyethylene products such as drum liners and rigid pail inserts.

Light duty
  • Very clear
  • Glossy finish
  • Between 100 and 120 gauge (25 and 30 microns).
  • Predominantly used for keeping items clean and dust free.
  • Poor for sharp or heavy objects.
  • Good fpr clothes, papers, buttons etc.
Medium duty
  • Between 200 and 250 gauge (50 and 62 micron).
  • Clear and glossy
  • Thicker film is easier to work with.
Heavy duty
  • Between 400 and 500 gauge (100 and 125 micron)
  • Suitable for weights up to 20 kgs.

The film thickness guide provides information on choosing a film thickness.

Polythene layflat tubing

Latflat tubing is made from a continuous tube of polythene on a roll. Layflat tubing is ideal for packaging long 'difficult to wrap' items.

Items can be inserted into the tubing which is then cut to the required length. The ends are then heat sealed, tied, stapled or taped shut to create made to measure bags.

Layflat tubing is made from low density polyethylene.

Polythene is made from crude oil and natural gas, a non-renewable resource.

Black layflat tubing is used where security maybe an issue.

Manufacturing layflat tubing
  • Layflat tubing is produced using the blown film extrusion method.
  • The polythene melt is extruded through an annular slit die vertically to form a thin walled tube.
  • Air is introduced through a hole in the centre of the die into the tube causing it to expand and form a bubble.
  • Mounted on top of the die, a high-speed air ring blows onto the film to cool it.
  • The tube of film continues upwards, continually cooling, until it passes through nip rolls where the tube is flattened.
  • This layflat tubing is then taken back down the extrusion tower via more rollers.
  • Layflat tubing is then either kept as such or the edges of the layflat tubing are slit off to produce two flat polythene film sheets and wound onto reels.
Advantages of layflat poly tubing
  • No need for a large inventory of different sized poly bags.
  • Great for packaging products that have odd sizes.
Is layflat tubing water tight?
  • Whilst it isn't completely airtight it is fully watertight.
Can I use layflat tubing for wrapping and freezing foods?
  • Polythene is temperature stable down to domestic deep freeze levels.
Can I use layflat as air-ducting?
  • Lots of people use layflat as cheap air-ducting.
What is the diameter of 12" layflat?
  • Layflat dimensions are half the circumference.
  • A 305mm wide tube does NOT fit a 305mm diameter pipe.
  • The fomula required is: diameter X pi = circumference
Can I make my own bags from layflat tubing?
  • You will need a heat sealer with a cutter to make life easy. If you are packing components of various lengths with a common width layflat is the ideal solution. It saves stocking loads of different bags.
What duty should I use to pack steel angle-iron?
  • You will need a heat sealer with a cutter to make life easy. If you are packing components of various lengths with a common width layflat is the ideal solution. It saves stocking loads of different bags.
  • Medium duty is not tough enough to hold the angle-iron.
  • Heavy duty will be ok.
What duty should I use for packing curtains?
  • Medium duty will be ok.
  • If shipping by carriers use heavy duty.

Polythene layflat tubing sheeting usage

Polythene sheeting is widely used to provide all year round tunnelling cover for green houses in commercial agriculture, forestry and gardening.

Highest quality raw materials ensures high transparency and protection against UV rays over a number of cultivation seasons.

Composting cover polythene sheeting is extremely robust against mechanical damage, resistant to compost acids and withstands aging caused by sun light for up 3 to 5 years.

Common usages
  • Dust sheets
  • Protecting pallets of goods.
  • Temporary floor covering.
  • The construction sheeting products are commonly used for: temporary roofing covers, protection of bitumen based water proofing, permanent subterranean damp proofing, water tight isolation of tanks and reservoirs, water proofing of various building partitions
  • Plastic sheeting is also used as underlays to provide smooth base for screeding and flooring.
  • Plastic sheets are widely used as temporary protection of materials on building sites.

Polythene garment covers

The following list gives a rough guide for selecting garment cover length:

  • Full length: Designed for covering extra long garments. (72")
  • Standard length: A versatile size. (60")
  • Jacket length: Used to cover many types of jackets. (51")
  • Blouse length: Used for standard blouses. (44")
  • Short length: Suited for smaller items such as t-shirt (36")

Polythene weight and thickness measurement

Plastic sheeting, tubing and bags are measured by their thickness and this is expressed in "gauge" (imperial) or "microns" (metric).

Gauge relates to thickness in "thou" (thousandths of an inch), and each 100 gauge is 1 thousandth of an inch. Thus 500 gauge is 5 thou thick.

Microns are thousandths of a millimeter. Thus 100 microns are 1/10th of a millimetre. Gauge can also be related to microns by dividing the gauge by 4. Thus 500 gauge polythene film is 125 microns.

Bubble wrap frequently asked questions

Bubble wrap is a light weight, transparent plastic material used for packing fragile and breakable things.

Bubble wrap is a plastic sheet with regularly spaced bubbles. These bubbles are actually air filled hemispheres which are spaced at regular intervals. These bubbles provide a cushioning to the items packed and prevent them from breaking. The bubbles in a bubble wrap are air filled and acts as a cushion.

Bubble wrap is used to pack breakable and fragile things like glass, crockery, mirrors and even electronic goods.

Bubble wrap comes in different sizes. The first type is the UPSable size roll. It is made from the same type of bubble wrap but in smaller size for goods sent via UPS. The industrial size rolls can have perforations for cutting them into smaller pieces. They can also be slit easily.

Anti static bubble wraps is designed to pack electronic goods. They are good for cushioning and are good for electronic goods.

Cohesive bubble wrap has a sticky substance which sticks to itself. This avoids the use of any additional tape. They don't stick to surfaces except to themselves. They do not leave any residue on the surface.

Adhesive bubble wrap sticks to the product itself. It can stick on all surface except wood. This will help in easy packing. Adhesive bubble wrap is clean and does not leave any residue on the surface and can be easily pealed off.

Cushioning prevents damage in transit from shocks and vibrations. Bubblewrap will squash and recover repeatedly. Corrugated materials will squash but not recover. Bubblewrap is cheap and effective and uses little material.

Is bubblewrap suitable for furniture?
  • Bubblewrap should not be used on polished furniture.
  • Bubbles tends to get imprinted on the surface.
  • We recommend using foam in 2.5mm thickness.
  • This is made for the furniture industry and is ideal for any highly polished wood surface.
Packaging with bubble wrap

While moving we can lose most of our precious things.

Proper packaging will help but not elimiate the problem.

For fragile products use bubble wrap. This is used to wrap the products that is fragile in nature.

You can pack fragile electronic equipments as well as glass products in bubble wrap.

Bubble wrap comes in different sizes. The cushioning effect will help you protect your important equipments.

Packaging and parcel tape

Packaging tapes are activated by pressure. The better you press it down the better it sticks. It is important to use a proper dispenser which applies the tape with a roller to press it down.

"Curing time" the is the time the tape takes reaches its maximum adhesion. In warm weather this maybe an hour or two. Its better to keep packages out of direct sunlight during this period.

Cold working
  • Tapes do not work well when its really cold.
  • It is advisable to keep the rolls in a warm place.
How do I apply tape to heavy boxes?
  • Bring down the flaps of the box.
  • Start with a "holding strap" of tape across the flaps to hold them in position.
  • Run a length of tape along the length of these so the join is under the middle of the tape.
  • The tape should run 50 to 75mm over the edge onto both ends of the box.
  • The tape is pressed firmly down onto the box to ensure good adhesion.
  • For heavy and export boxes it is advisable to add a further strip of tape across the ends of the flaps.
Different types of packing tape
  • Clear or brown packaging tape is used for standard packing.
  • Polypropylene tape is clear plastic tape that is strong, durable, and is very resistant to breaking. Polypropylene tape cannot be torn by hand and requires scissors, knives, or a dispenser to use.
  • Cross weave filament tape is good for keeping items secure and reducing the risk of accidental opening by unauthorized parties. The filaments make it difficult to open the package by hand, making shipments more secure.
  • Masking tape is not very strong and removes cleanly.
  • Printed fragile tape is designed to let couriers and handlers know that the consignment is fragile. Fragile tape tape is normally white with the word ?fragile? printed in red bold letters.
  • PVC tape provides a high quality taping with high performance and strong support for all types of shipping needs.
  • Kraft paper tape is designed to blend well with boxes while providing a high adhesive for many different applications. Kraft paper tape is brown in colour and is easily torn by hand.
Choosing packaging tape
  • Custom printed tape can be printed with your logo and message to build brand awareness and give information or instructions. Custom tape can be printed on a white background tape or a coloured background.
  • Vinyl tape is very strong, tear resistant and waterproof. Vinyl tape offers superior performance for sealing cardboard boxes and other packaging. Vinyl tape comes in 50mm and 75mm widths and is resistant to extreme temperature fluctuations.
  • Coloured tape is ideal for sealing your cardboard boxes and colour coding them all in one go. Coloured tape saves time and money not having to put separate labels on the boxes.
  • Cloth tape is waterproof with a strong and reliable performance. Due to its industrial grade it is ideal for duct work, general repair, reinforcement and export packaging. Cloth tape is widely available in black or silver at 50mm width.
  • Double sided tape is made from polypropylene with adhesive on both sides of the tape and a silicon release paper. With widths of 25mm or 50mm the tape can hold very heavy weights.
  • Masking tape is made of creped paper and is largely used in the automotive body building and repair trade, building and construction and many other industries. Masking tape is easy to tear and removes cleanly from the surface of the product it is used on.
  • Filament tape is used for packing heavy consignments. Filament tape is cross woven with glass filaments to provide high tensile strength. Filament tape is suitable for heavyweight strapping applications, export packing and bundling.
  • Tamper evident tape gives you some protection from people tampering with your packages. The polypropylene security tape is designed to reduce pilferage and unauthorized opening of packages.
  • Gummed paper tape provides a secure, tamper evident seal. Gummed paper tape forms a complete fibre bond with the sealed carton and is unaffected by extreme temperatures of -50 to 100 centigrade. Gummed paper tape is ideal for export and deep freeze.
  • Hazard warning tape can guard your workforce against accidents. Hazard warning tape is suitable for use both indoors and out. Red and white hazard warning tape is used for fire hazards, extinguisher locations etc. Green and white hazard warning tape is used for safety equipment and emergency exits etc and black and yellow tape for hazardous areas and obstacles. Barrier hazard hazard warning tape is used extensively by local authorities, road maintenance contractors and police etc. for restricting access to excavations, accident sites or work areas temporarily out of bounds.
  • Floor marking tape is made of strong plasticised PVC and is used for lane identification and floor marking in sports halls etc.

Plastic bag size calculation guide

For lining a box

  • 1) Measure the width, depth and height of the box to be lined. The depth should be the shorter side.
  • 2) To determine the width (W) of the bag, add 1" to the width of the box.
  • 3) To determine the depth (D) of the bag, add 1" to the depth of the box.
  • 4) The length (L) of the bag is determined by adding the depth plus 1" to the height plus 1". Add another 5" to allow coverage of the box contents.

For a round container

  • 1) Measure the diameter and height of the container to be lined.
  • 2) To determine the circumference (C) of the container, multiply the diameter by 3.14.
  • 3) To determine the width (W) of the bag, divide the circumference (C) by 2. Add 1" for a looser fit.
  • 4) To determine the length (L) of the bag, add the diameter to the height. Add 5" for overhang.

For a square container

  • 1) Measure the width, depth and height of the container to be lined. The depth should be the shorter side.
  • 2) To determine the width (W) of the bag, add the width and depth. Add 2" for a looser fit.
  • 3) To determine the length (L) of the bag, add 1/2 the depth to the height. Add 5" for overhang.

For a pallet cover

  • 1) Measure the width, depth and height of the pallet to be covered. The depth should be the shorter side.
  • 2) To determine the width (W) of the cover, add 1" to 2" to the width of the pallet.
  • 3) To determine the depth (D) of the cover, add 1" to 2" to the depth of the pallet.
  • 4) The length (L) of the cover is determined by adding 1/2 the depth to the height.

Polythene bag gusset definition

Some bags have a gusset at the sides to help the bag open out more and enable a greater volume of items to be put in - a good example is a refuse sack.

A side gusset is expressed as a bag being x" wide opening to y" wide.

For example: if a refuse sack is 16" x 25" x 39" this means it is 16" wide opening to 25" wide when the gusset is opened, with a bag length of 39".

Others have a gusset at the bottom to enable a wide product to fit in - a good example is a carrier bag.

A bottom gusset is expressed as + x". For example: if a carrier bag is 15" x 18" + 3" then the carrier is 15" wide by 18" long with a bottom gusset of 3".

Pallet Strapping materials and usage guide

Why use strapping
  • Pallet strapping is used to secure bundles of product typically for shipping and storage.
  • Strapping inventory extends the life of the product by keeping it safe and protected during shipping or storage.
  • Strapping frees up space by keeping like materials together in neat bundles.
Rule of thumb
  • (weight of pallet x 1.5) / number of straps applied = tensile requirement of the strapping
  • For example if maximum pallet weight is 1100# with 3 straps applied (1100 x 1.5) / 3 = minimum 550# tensile strength required.
  • The recommended strapping would have 600# tensile strength.
  • Note: The higher the pallet height and/or the heavier the pallet weight, the more important the need becomes for either a higher tensile strapping or more straps.
Extruded polyester strapping
  • Polyester strapping is the strongest plastic strapping material.
  • The highest initial tension can be applied and retained over a period of time compared to other plastic strapping materials.
  • Extruded polyester strapping is the most rigid of all strapping materials.
  • Polyester is nick resistant and can be sealed with seals, heat or friction welds.
  • Polyester offers the greatest strength and highest retained tension of all plastic strapping.
  • Extruded polyester strapping is frequently used on heavy duty loads that need high initial tension along with high retained tension during handling and storage.
Polypropylene strapping
  • Polypropylene strapping is the most economical type of plastic strap and is adequate in many applications.
  • Polypropylene strapping is the most commonly used and least expensive of all strapping materials.
  • Polypropylene strapping is light and easy to apply and recycle.
  • Polypropylene strapping characteristics include high elongation and recovery and low retained tension.
  • Polypropylene strappling is avaliable in both manual and machine grade and can be sealed with buckles, seals, heat seals or friction welds.
  • Polypropylene strapping is an excellent choice for light duty palletizing, unitizing, carton closing and bundling.
  • Polypropylene strapping can be used in all semi-automatic strapping machines.
  • Polyprop strapping has a break strength up to 2000# and comes in many different colors.
Steel strapping
  • Steel strapping is the strongest of all strapping materials.
  • Steel strap is recommended where high strength is necessary, low elongation is important and where the product is extremely sharp or hot.
  • Steel strapping is sealed using snap on seals and lap over seals.
  • Ribbon wound steel strap is wound once.
  • Oscillation wound steel strapping is wound on top of each other again and again.

Stretch film and pallet wrap information

The idea of stretch film or pallet wrap is that tension is used to hold a number of items together.

Clear film is manufactured from cast polythene, this gives it better clarity and reduces the noise when the film comes off the roll.

This ensures stability of the items held, along with the benefit of being protected from dust and to a lesser extent rain.

Black pallet wrap can be used to shield items from view.

To use stretchfilm in the correct manner tension must be applied to the stretchfilm as it is wrapped around the items. The palletwrap must be pulled taut as it is wrapped around the items.

Pallet wrapping stretch films
  • Place the outside of the film to surface of pallet.
  • Tye the stretch film to the pallet base.
  • Ensure film covers the base of pallet and the bottom layer of the load.
  • Wrap bottom of pallet at twice to secure load.
  • Overlap the stretch film by 30 to 50%.
  • Depending on the weight of your load, consider wrapping the pallet twice.
  • To increase the strength, use the film horizontally to create a "strap".
  • use a handheld stretch film dispenser for rapid easy application and to prevent injury through straining or repetitive use.
Selecting shrink film thickness
  • You can buy shrink wrap film in the thicknesses: 12.5/13 microns, 15 microns, 17 microns, 19 microns, 21 microns and 35/38 microns.
  • You should use the thinnest gauge of shrink wrap that will be strong enough to properly wrap your pack. This makes sense from an environmental perspective.
  • Thinnest shrink films: 12.5/13 micron shrink films are the thinnest shrink films available. It will suit packs where the shrink film is supported.
  • Shrink films for heavier and larger packs: 15, 17 and 19 microns shrink wrap will be proportionally stronger. 21/25 microns shrink wrap allows collations of packs. 35/38 micron shrink film material is demanded for large and heavy packs.
Selecting shrink film width
  • Shrink film width is calculated by adding the width and height of the pack together, increasing this figure by 10% and adding 60mm for the necessary scrap.
  • As shrink film widths are normally incremented at 5cm per time, you should round up the figure if the width you calculate falls between the increment section.
Calculating the number of shrink wrapped packs
  • Add the height and length together, increase it by 10% and then divide this figure into the length of the roll.
PVC and polyolefin shrink wrap
  • Film strength - polyolefin shrink wrap seals are stronger as is polyolefin in terms of puncture and tear resistance, and low temperature flexibility.
  • PVC shrink film loses strength proportionally as ambient temperature drops.
  • Cleanliness - PVC shrink wrap creates carbon deposits on sealing wires and blades which need regular cleaning. In addition, the sealing process will produce small quantities of hydrogen chloride, which will cause the equipment to rust over time. It should be noted that adequate ventilation must be provided when - any - shrink film is used
Types of stretch wrap
Cast stretch wrap Blown stretch wrap
Load retention Stretches easily. Slightly more force required to stretch film.
Film yield Additional stretching can be obtained easier through lower micron blown films. Re-stretching the film once its applied is extremely difficult.
Clingyness of the film Naturally clingy on both sides. One sided clingy only.
Visual clarity Perfectly clear, makes reading and scanning in warehouse light easy. High gloss can cause reflections. Hazy and dull which makes reading more difficult. It has lower gloss with reduces reflections.
Noise on unwinding Very quiet when being unwound. Loud when being unwound from the roll.
Puncture resistance Good puncture resistance. Tearing can occur if stretched too much. Great puncture resistance.
Benefits of cast stretch wrap

Cast stretch wrap has the following features:

  • lower cost option than blown film
  • high strength
  • high tact
  • good puncture resistance

Carboard carton boxes frequently asked questions

Measuring a box
  • Length - From the base of a box, the length is the longest side.
  • Breadth (width) - From the base of a box, the breadth is the shortest side.
  • Height (depth) - From the side of the box, measuring from the base to the top is the height.
  • length x breadth x height = cubic volume
Choosing a box
  • Arrange the items as desired. Measure the length, breadth and height of the items. This gives the minimum box dimensions for accommodating the products.
Cushioning items
  • Polystyrene loose fill chips cushions your products and prevents damage during transit or storage.
  • Allow extra space around your products and increase the size of your box.
  • The more protective material you can accomodate the more protection you'll give to your items.
Using a hand tape dispenser
  • Hand tape dispensers make the application of sealing a box using packing tape easier and faster.
  • Lay the tape dispenser on a flat surface with the tape wheel facing up.
  • Slide the core of the packing tape over the tape dispenser wheel.
  • Ensure the whole wheel is covered by the core of the packing tape.
  • Feed the packing tape, adhesive side down, through the roller and metal plate.
  • Pull the packing tape through the tape dispenser to ensure the tape flows freely.
  • Press the tape dispenser onto the cardboard box you wish to seal and pull the dispenser back.
Sealing a box

The most secure way to seal a box is the 'H' seal method. The H seal method allows for all the flaps of a cardboard box to be sealed, giving extra protection. The H seal method also shows a high level of tamper evidence as there is more tape to remove.

  • Using a packing tape dispenser, start from the side of the cardboard box and pull the packing tape dispenser back and over the top of the box to seal the two flaps.
  • Continue to pull the tape dispenser back across the top of the cardboard box and allow a further few inches of tape to follow down the side of the box.
  • Pull the packing tape dispenser down so the blade will cut the tape at the required point.
  • Use the packing tape dispenser to seal the edges of the cardboard box in the same way as the top but allow an overhang of tape.
  • Fold over the overhang of tape to the side of the cardboard box.
  • Repeat on the other side and seal the bottom of the box as previously done.
  • When you have finished, your cardboard box will be sealed on all sides, displaying a H on the top and bottom of your box.

Packaging envelopes frequently asked questions

Choosing the correct envelope size

The most widely used envelopes sizes are C4, C5, C6, padded and DL.

  • Envelope of C4 size can hold sheet of A4 size. The dimension of this type of envelope is 324mm x 229mm. They are available with peel and seal flaps and are available in hues such as white and brown colour. Envelope of C4 size could be used for mailing hefty documents and delivery notes.
  • Envelope of C5 size can hold sheet of A5 size. The dimension of this type of envelope is 229mm x 162mm. They are available with peel, seal flaps and double security self-seal flaps. They are available in brown and white hues. It is the most commonly used envelope size for purpose of mail shots and business letters. The weight of envelope of C5 size should range from 90 gsm to 130 gsm (grams per square inch).
  • Padded envelopes are mostly used for mailing heavy documents. The benefit in using these envelopes is the aspect of protection and security which they provide. They are resistive to tear and damage so you can be tension free about the delivery of your stuff with utmost security and protection. Non-fragile items could be sent using this envelope. This kind of envelope has a layer of bubble wrap attached at inner side. Through the bubble wrap, one can hardly find out about the stuff inside the padded envelopes. Even non-fragile items could be sent using this envelope.
Different types of envelopes
  • Common letter envelopes are the workhorse of most direct mail marketing campaigns. The common envelope types for this category are the #9 and #10 envelopes with dimensions 3 7/8 ? 8 7/8 inches and 4 1/8 ? 9 1/2 inches respectively. Both of those are longer envelopes, perfect for a few pages of letters with marketing messages. Of course, they have a wide area, which is useful to fit a special envelope printing design if you want. There are smaller envelopes in use as well. These are the A6 and the A7 envelopes with the dimensions 4 3/4 ? 6 1/2 inches and 5 1/4 ? 7 1/4 inches respectively. These are used for shorter correspondences and marketing messages. They are cheaper to print making them a perfect choice for budget marketers.
  • The baronial envelope is a special kind, which is well suited for invitations, greeting cards and other formal announcements or communications. Most direct mail marketers refrain from sending these types of envelopes since baronial envelopes are not well suited to some postal services and machines. However, baronial envelopes carry a unique significance unto their own that makes people want to open and read the message inside. Since a baronial envelope's character usually portrays it as a bringer of good news, a marketing mail can exploit that character to its advantage. The typical size of a baronial envelope that can be mailed is 4.375 x 5.75 inches. Some baronial envelope can be too small however for mailing.
  • Booklet and catalog envelopes are envelopes that are used to mail or store booklets and catalogs. The typical sizes for these kinds of envelopes are 6x9, 9x12 or 10x13 inches. The only difference between booklet and catalog envelopes is the location of their seams. Catalog envelopes have a seam located at the center, which makes it stronger. This makes it more apt to carrying heavier printed materials such as a thick catalog. Booklet envelopes however have a side seam, which is more typical of the seams of common letter envelopes. If you are mailing marketing booklets and catalogs, investing in custom envelope printing and design can really help make that mail more appealing. Those are the major types of envelopes to use for direct mail marketing.
ISO 269 defines several standard envelope sizes
Envelope sizes
Format Dimensions (HxW mm) Dimensions (in) Suitable for content format
DL 110 ? 220 4.33 x 8.66 1/3 A4
C7 81 x 114 3.2 x 4.5 1/3 A5
C7/C6 81 x 162 3.19 x 6.4 1/3 A5
C6 114 ? 162 4.5 x 6.4 A6 (or A4 folded in half twice)
C5 162 ? 229 6.4 x 9 A5 (or A4 folded in half once)
C4 229 ? 324 9.0 x 12.8 A4
C3 324 ? 458 12.8 x 18 A3

Choosing acceptable protecting packaging

If a little item you are sending thru the post has sharp edges or an uneven shape, a padded envelope may be suitable.

Theres always the danger of damage to anything you send by post or by courier.

Bottles containing liquid should be wrapped in polythene, sealed with tape and besieged with padding materials and newspaper or other absorbent material, in case of leaks.

Books sent through the post can suffer damage to their corners or binding.

When sending PC disks, video cassettes, DVDs and CDs, thick cushioning material should be wrapped round the item, which should then be enclosed in a stiff container.

Flowers should be packed in layers, with tissue paper parting them.

Vulnerable electrical equipment and brittle items need significant protection, including at least 10cm of cushioning material and a robust stiff container of the type that may prevent the item moving within it.
