Polythene packaging is one of the most important things in our everyday lives as it is used for a huge range of day-to-day tasks, from keeping our food fresh to helping keep our homes clean. There is a massive range of polythene packaging that we rely on in the home and workplace, including plastic bags such as packing bags, carrier bags, mailing bags, bubble bags and grip seal bags, waste bags such as bin liners, bin bags and black sacks, polythene rolls and other polythene items on the roll, such as garment covers, poly tubing and plastic sheeting, along with biodegradable packaging such as compost bags and dog poo bags.

Have your say about polythene packaging

Specialist packaging at the superior stop succeeds when the material behaves properly on the line and in the warehouse, not only when it sees tidy at point of sale. A sleeve or bag with uneven gauge can clog sealing jaws, trap air, or leave weak spots that only display up after stacking and movement through dispatch. Static control matters as much as print or stop when finely manufactured components are involved, because cling and dust select-up can turn a clean pack into a handling problem. Good specifications retain film tension, seal quality and conversion speed in balance, which reduces stoppages and rejects. That kind of control saves time on the shop floor and cuts the chance of damaged stock reaching the client.

Vacuum Packaging Terms

Vacuum packaging extends shelf life because removing air slows the changes that spoil food and other sensitive products. The proper benefit comes from cutting the oxygen inside the pack, which reduces oxidation and makes it harder for plenty microbes to grow. That is why the film, tray and seal all have to work together properly: a poor seal or a weak laminate can let air creep back in and undo the protection. Gauge selection matters also, since a film that is also thin may puncture amid handling or collapse badly in transit. A sound vacuum pack gives cleaner storage and less write-offs.

Mailing bags need to suit the job first, because a weak bag or the gross size causes torn corners, split seams, and messy dispatches. A superb polythene suppliers mailing bag should match the contents closely, with enough room for easy packing nevertheless not so much space that items slide around in transit. Seal quality matters only as much as film strength, since a poor closure can open in the sorting chain or amid rough handling. Coloured bags also assist at select-face and despatch, particularly where alternative mail streams need fast identification. The proper selection reduces damage, speeds packing, and retains parcels looking tidy when they reach the client.

Display bags for medical devices need a firm structure as well as a clean see, because a tidy hook display means small if the pack sags or twists before it reaches the shelf. Clear face film assists the product stand out at the select-face and speeds stock identification, nevertheless the proper test comes in cartoning, pallet movement and dispatch handling. If the film gauge drifts, the header can curl, the seal can open below strain, or the bag can lose enough shape to see untidy beside competing stock. Good presentation relies on controlled converting and consistent film tension, not on appearance alone.

Biodegradability standards for carrier bags and plastic films in aquatic environments: a critical review

Carrier bags are judged badly when laboratory claims ignore how the finished article is manufactured and handled. A thin polythene suppliers bag may see impressive in a beaker test, nevertheless film orientation, gusset folding and stack pressure change how it behaves in proper use. What matters on the shop floor is whether the bag retains its shape, carries weight without split seals, and transports cleanly through packing, palletising and dispatch. Mixed additives or layered structures can also make recovery harder, because a bag that seems to smash down in one test may still leave material that is awkward for recycling. That is why specification should be built around the finished bag, not a cut-up sample, if the claim is meant to mean anything in service.

Bubble Packaging

Bubble packaging earns its place when mixed consignments need light protection without adding much weight, because the material is doing above filling voids. The quality of the film matters as much as the air inside it: if the gauge is inconsistent or the seals are weak, the bubbles collapse also easily and the wrap stops cushioning properly. Better grades retain their shape below pressure, which assists when cartons are stacked on a pallet and secondary packing has to stay tidy. In a busy packing area, that reliability cuts handling damage and retains the load stable enough for dispatch without constant rework.

Packing Bags

Packing bags improve case packing by keeping loose items below control without crushing them flat. A woven cotton building gives a softer contact surface, so knitwear, shirts and shoes are less likely to select up scuffs amid transit or storage. The drawcord top closes the bag firmly enough to stop contents spilling about, yet still leaves air space for the products to retain their shape. That matters because the aim is not to create space from nowhere, nevertheless to remove awkward gaps and unstable bulges in the luggage. When the bag is properly manufactured, the suitcase or consignment stacks more neatly and suffers less handling damage.

The Future of Rigid Plastic Packaging to 2022

Rigid plastic packaging volumes in Asia tell a story of proper industrial demand, not only consumer preference. Where a board carton can soften with moisture or a flexible pack can shift below load, rigid formats retain their shape through filling, stacking and shopping display, which makes them easier to dash on fast lines and easier to count in warehousing. Material selection matters as much as volume, because PET, PP and HDPE each behave differently in moulding, sealing and recycling streams. A rising tonnage figure normally means more trays, tubs and bottles moving through the chain, which puts pressure on resin supply, pallet stability and waste handling.

polythene suppliers packaging earns its place on the line when gauge control, seal strength and puncture resistance are tight enough to retain fast filling equipment running without constant stops. A film that is also thin tears at stress points, while one that is also heavy adds cost and waste without improving performance, so the proper job is matching the material to the product and the machine. Reel quality matters as much as the nominal spec, because poor consistency shows up fast as split bags, weak seals or static problems. That is why superb procurement and careful machine install save more trouble than a last-small fix on the shop floor.

Biodegradable packaging is often chosen because it can cut the burden of waste handling when the specification matches the product and the disposal route. A pack that smashs down below the proper conditions can reduce the amount of persistent material entering the bin stream, nevertheless only if the board, film, or bag is selected for the proper use. Poorly matched materials can still fail in storage or transit, particularly if moisture, heat, or long warehouse dwell times are involved. That is why the proper test is not the label alone, nevertheless whether the pack protects the products and still fits the waste system at the stop of life.

Common forms of packaging

Polythene packaging comes in many shapes and forms to cover a multitude of tasks. Here are a few of the most commonly-used forms of packaging:

Packing bags - clear polythene bags used for a range of tasks, from packing and displaying retail products to covering items for storage or transportation.

Display bags - popular with retailers, these crystal clear polypropylene glossy display bags will make your products sparkle!

Carrier bags - plain or printed polythene bags designed to help retail customers carry their purchases home. Available with a variety of handle styles.

Garment covers - polythene covers used to protect dry cleaning or laundry during transportation or storage. Available in plain or printed polythene.

Bubble packaging - polythene sheets comprised of small air-cushioned ‘bubbles’ that protect delicate or fragile items during transport or storage. Also available in bubble bag form, complete with sealing strip.

Vacuum packaging - used in the catering industry for sealing food before cooking in a water bath (sous-vide - see below), or storing food to keep it fresh. Requires a vacuum sealer to seal the bags.

Polythene rolls - Polythene film available on the roll used for a variety of packaging purposes, including layflat tubing, shrink pallet covers and glossy display film.

Plastic sheeting - Thicker rolls of polythene, also known as builders rolls, used to cover wide areas in the building trade and by painters and decorators.

Specialist packaging

Away from the everyday carrier bag and Here are some of the more specialist types of polythene packaging. But whilst they might be less frequently used, they are no less important.

Anti-static bags - a range of bags that protect electrical equipment and small electronic components from the potential damage caused by electrostatic discharge.

Box liners - a range of large polythene liners featuring a wide gusset, used for lining boxes or drawers, or as a packing cover for large or bulky items.

Fish bags - strong clear polythene bags that come with watertight seals, used to transport goldfish and other types of fish. Popular with pet shops, aquaria and funfair stall holders.

Mattress covers - High strength gusseted polythene film covers used to protect mattresses. Available for single, double or king size mattresses and come complete with safety warning.

Vacuum packaging and sous-vide cooking

Every gourmet restaurant kitchen worth its salt these days will contain a vacuum sealer and a collection of vacuum bags. Not only does a vacuum sealer allow chefs to store food in an airtight environment, thus keeping it fresh for longer, but it can also be used in the cooking process.

Chefs use vacuum packaging for sous-vide cooking - a method of cooking in which food is sealed in an airtight polythene vacuum bag before being cooked in water at a specific temperature to ensure it is cooked evenly throughout, without losing any of its moisture.

The technique is similar to poaching but, by sealing the food inside a vacuum pack, it has the advantage of retaining the juices and aroma of that would be lost during poaching.

Sous vide is a technique used in many high end gourmet restaurants and is popular with well known chefs including Heston Blumenthal, Michael Carlson and Joël Robuchon.

On a roll - plastic or polythene?

Polythene packaging dispensed from a roll can be referred to by a large number of terms, covering a range of products that serve very different purposes. However, often the terms used to describe these rolls are mixed up and people can refer to plastic or polythene film when meaning the same thing, or they might use the same term - e.g. polythene rolls - when referring to two completely different products.

In the trade, for the most part, ‘plastic rolls’ is a term used to describe rolls of thicker plastic sheeting - often referred to as builders rolls - that protect large surface areas or objects from the dust, debris and generally mess caused by building, painting and decorating. Damp proof membrane, used in the early stages of the building process, is classified as a heavy duty plastic roll.

The term ‘polythene rolls’, on the other hand, would most likely be used to describe rolls of thinner polythene film used to wrap or cover items, such as shrink wrap, pallet covers, glossy polypropylene display film or - when dispensed in tube form rather than a single layer - layflat tubing.

If you’re working with someone who refers to a plastic roll or polythene roll, ask them to be a bit more specific so that you know you’ll get exactly what you need for the job in hand.

Eco-friendly packaging

Packaging is such an integral part of everyday life in the 21st century that it’s hard to imagine a world without it. But with global warming and other environmental concerns becoming more and more important, many people look to replace their regular packaging with eco-friendly alternative.

What is eco-packaging?

Eco-packaging is a form of packaging that, rather than using traditional polythene, uses alternative materials that are biodegradable, thereby having less of an impact on the environment.

A wide range of eco-friendly packaging is manufactured today from polybio and biodegradable material, that will completely biodegrade when placed in regular composting conditions, landfill or into prolonged contact with soil.

Types of eco-packaging

You can have one eye on the environment while doing a wide range of household tasks these days and there’s eco-packaging to help you along the way.

Popular types of eco-packaging include biodegradable bin bags, refuse sacks and wheelie bin liners, kitchen waste bags and compost bags, biodegradable mailing bags, biodegradable clear bags, biodegradable carrier bags and even dog poo bags.
