Shrink film suppliers operating in the polythene suppliers sectour are increasingly judged less by list of products breadth than by their command of film behaviour below proper packing-line strain: gauge tolerance at the micron level, melt-flow consistency across reels, and the rather prosaic question of whether a sleeve will pull down cleanly without distorting a tray or scuffing printed outers at speed. PE shrink film sits in a demanding middle ground; the high-density and low-density polymer fractions must be balanced to give puncture resistance without leaving the pack board-like, while slip, haze and surface resistivity all affect how stock travels through infeed, collation and heat tunnel stages. On the warehouse floor the discussion becomes still less theoretical. A few grammes saved in tare weight can alter pallet stability, cube utilisation and consignment density, yet excessive downgauging invites split corners, rewraps and secondary bagging, which erode any apparent material economy. The more capable suppliers so tend to behave as process partners, matching film recipe, reel presentation and shrink profile to select-face efficiency and transit abuse rather than merely quoting roll dimensions. Circularity adds another layer: mono-material polythene suppliers formats facilitate cleaner recovery streams, nevertheless only where inks, labels and pollution are kept within sensible limits, and where recycled-content ambitions do not compromise seal integrity or tunnel repeatability. In that context, procurement becomes a technical discipline; the better question is not who can supply PE shrink film, nevertheless who can maintain a stable, recyclable, line-compatible material across changing feedstock and seasonal operating conditions.

Pallet Covers

Pallet covers tend to be treated as a lowly consumable until a mixed consignment sits in a damp marshalling bay or a high-bay aisle throws up enough dust to foul outer cartons; then the engineering detail becomes rather less optional. Lightweight polythene suppliers covers, properly specified, do above drape above a load: micron-specific gauging has to balance tear propagation against tare weight, while controlled breathability prevents the familiar problem of trapped condensate softening fibreboard and compromising pallet stability below stretch wrap. For stock moving through variable temperature zones, a water-resistant cover with uniform surface behaviour mitigates grime ingress without creating a sealed microclimate around the products; that distinction matters on the warehouse floor, where select-face efficiency, secondary bagging and rework all transport labour penalties. The better coverings also sit neatly within a circular economy argument, particularly where mono-material building and consistent melt-flow properties enable cleaner recovery into secondary film streams. In practice, the specification is a negotiation between volumetric efficiency, handling abuse, load profile and disposal route a modest sheet of polythene suppliers, perhaps, nevertheless one that quietly determines whether the pallet arrives clean, dry and still square.

Cook-In Shrink Bags

Shrink bags for poultry sit at the awkward junction between presentation, hygiene control and cool-chain pragmatism: the film must draw tightly around all birds and bone-in breast packs without bridging above cavities, splitting at protruding bone ends, or leaving water traps that degrade the pack face in a chill cabinet. In practice this means careful selection of polythene suppliers or co-extruded shrink structures with controlled puncture resistance, seal initiation temperature and micron-specific gauging; also heavy a gauge adds tare weight and cost through the line, also light a web risks leakers after drop-chilling, blast-freezing or cage-to-pallet handling. The better-performing formats are engineered around consistent shrink memory and low haze, allowing the carcase shape to remain legible while limiting purge migration and freezer burn. On the packing floor, the earns are less glamorous nevertheless significant: less rewraps, cleaner secondary bagging, steadier select-face efficiency and improved pallet stability because packs settle into a more uniform cube. The sustainability argument is not simply less polythene suppliers; it rests on downgauging without loss of abuse resistance, mono-material recyclability where assortment systems enable it, and melt-flow consistency in recycled feedstock so sealing and shrink response do not wander from one consignment to the next.

Here are just a few of the main product categories that Polybags has to offer:

Shrink wrap systems

Want to learn about the different types of shrink wrap systems? Well you've come to the right place. Here are the most popular kinds of shrink wrap systems available today.

Straight bar sealers - A straight bar cuts and seals the film manually. For low volume applications.

L-bar sealers - An L-shaped bar used to cut and seal shrink film. Averages between 0-40 packages per minute, depending on automation level (e.g. manual, semi-automatic, automatic, automatic continuous). Also known as: impulse sealer, sealing system, sealing equipment, L-sealer, L bar sealer.

Sleeve wrappers - Designed to wrap trayed or loose collated items. Mainly used in shipping applications. These shrink wrap systems often replaces corrugated boxes and other types of packaging that are costly and need more space to use, store & dispose of. Also known as: shrink bundler, shrink wrapper, heat wrapper, sleeve shrink equipment, sleeving system.

Form fill seal shrink wrap equipment - The ultimate shrink wrapper, designed for high speed shrink packaging applications, averages between 30 -100 packages per minute on a continual basis. Most applications use polyolefin shrink film / industrial shrink wrap film.

Heat shrink wrap systems

Shrink tunnels - The final step in shrink wrapping. Package is passed through the shrink tunnel. Once inside the zone of the tunnel, it is subjected to increased levels of heat and turbulent air flow. A quality tunnel is capable of producing the required amounts of heat and air flow to cause the film to shrink around the introduced package. Also known as: heat tunnel, shrink film tunnel, shrink wrap tunnel and shrink heat tunnel.

Heat guns - Hand held tools that blow hot air to manually shrink film. Low volume output.

Shrink film sealing systems

Until recently, most sealing systems used a hot wire in order to seal and cut-off the film at the same time; now, a knife system has gained in popularity on many models due to its durability.

The wire or knife seals the film against a pad, covered with Teflon tape to protect the pad. Time, temperature and pressure are the three most critical elements affecting the seal quality. If the sealing head is not held on the film long enough, the temperature is too low, or the pressure is insufficient or uneven, the seal quality will be poor and/or won't cut.

However, if the sealing temperature is too high, the film may break just behind the seal. Following the impulse-sealing cycle, a cooling cycle allows the film to solidify into a solid seal. This dwell-time is critical in order for a seal to hold.

PVC films require only heat in order to cut seal and cut. When run on a sealing system as previously described, buildup of carbon char (black specks and flakes) will occur. This needs to be cleaned from the sealing head on a regular basis, otherwise the carbon will interfere with the sealing process and will look unsightly on the sealed ends of the package.

Since only heat is needed to form a PVC seal, some machines use a hollowed out bottom plate instead of the foam pad; direct contact with the seal wire is eliminated. Other systems employ a much thinner nichrome wire (.020" diameter vs. a standard .036" to .040" for polyolefins) against a hard bottom sealing pad. This system is insufficient to create strong polyolefin seals.

One other sealing system designed for PVCs is called a universal sealing system. Despite the name, the hot knife is typically too sharp to form a quality polyolefin seal. A rounded knife is better suited.

Shrink film shrinking systems

In order for proper shrinking to take place, polyolefin films need an air evacuation hole or multiple perforations. A bag formed with PVC film does not need 'artificially created' air escape holes. Because of the make-up of PVC, the seal typically is full of small pinholes; this is where the air escapes during the shrinking process. While this may seem advantageous (a step can be eliminated), the small holes actually weaken the seal area. These holes are often located near or in the package corners.

In order for proper shrinkage to occur, polyolefin film must be exposed to the correct temperature for the correct amount of time (which is controlled by conveyor speed), and also be surrounded by the correct air velocity, or wind turbulence. The air allows the film to stand away from the product, and a 'bubble' is formed around it. A good, even shrink should result when this occurs.

PVC films shrink readily when exposed to heat, and therefore air velocity is not critical. In the marketplace there are low-end tunnels which have no settings to control air velocity (similar to an oven) and you may find it difficult to achieve a good shrink.
