Polythene
Polythene is generally used for producing plastic sheeting and plastic bags. Both of which come from the same manufacturing process. Polythene pellets are melted and then extruded through a circular die gap forming a plastic tube, the die can be adjusted to produce different diameters. The tube can also be made thin or thick by stretching and inflating. The tube can also be cut in one or both sides or be gusseted. The cooled polythene tube is then rolled at the end of the process. All of this is done in the same machine in a continuous flow.
Printed Packaging
Polythene packaging can also be made printed with custom logos and designs. Printed packaging provides an effective marketing solution. By printing a logo, company name and/or a website address on a shopping bag will enable a company to be advertised for wherever the printed bag goes and it will also become recognizable.

Non standard sizes and thiknesses can also be made to order. Biodegradable clear bags are also manufactured as an alternative to polythene bags.
High tensile bags
For a more demanding solution, if packing heavier loads for example, high tensile bags could be used. High tensile bags are produced with a blend of low and medium density polythene providing improved strength when compared to standard polythen bags.
Polymax bags
Polymax bags are super strong bags manufatured by Polybags. Although polimax bags are stronger than the comparable low density polythene bag they are 25% cheaper and 66% thinner. Polymax bags can offer a great deal of strength, good visibilty and better tear resistance.
Grip seal bags with write-on-panels
These are polythene self-sealing bags manufactured with 3 not glossy white write-on-panels allowing foe labeling contents with a pen or pencil. Standard polythene self seal bags are 200 gauge thick.
Biodegradable compo bags
Biodegradable compo bags are made with chemical properties that helps them to biodegrade in a compost or landfill. Once disposed in a compost heap it will usually decompose in 9 months to 2 years along with its organic waste.
Slider grip bags
Slider grip bag is a self sealing bag with a plastic slider grip seal closure found in a variety of sizes. An economic solution for a professional packing look. Self-seal bags are also provided with extra bag strength 350 gauge polythene.
Specimen bags

Medical sample bags will keep the specimen safe from contamination, police bags and forensic bags will avoid the evidences from losing its properties.
Antistatic grip seal bags
An antistatic bag is a shipping bag for electronic devices which can be damaged by electrostatic discharge. Static travels around the bag and dissipates before it has a chance to damage contents when shipping or storing. These plastic bags have a distinctive color (silvery for metalized Mylar and other similar plastics, pink or black for polyethylene). The polyethene bags may also take the form of foam or bubble wrap, either as sheets or bags.

Layflat tubing or film on the roll is a flexible and economical form of packaging. LFT is perfect for packing products of the same width but varying in height or long items. Layflat tubing is generally provided in as a roll of continuous film.
Top tips from the internet on buying polythene bags
Rubbish bags
Pre-paid waste bags only do their job when the material is matched to the waste stream. A thin sack may see fine on paper, nevertheless sharp offcuts, damp waste and rough handling quickly expose weak spots, and one split bag can leave a trail in the yard or on the street. A better gauge resists tearing and puncture, so the load stays contained through lifting, stacking and transport. That also makes life easier at the depot, where less breakages mean less spillage, less cleaning and less time spent dealing with a mess that should not ever have happened.
Waste bags need to be manufactured to a proper gauge if they are going to cope with the rough side of laboratory and clinical use. Thin film can split when sharps, damp waste or awkward corners are put in also quickly, while above-heavy material can be wasteful and harder to handle in busy rooms and assortment trolleys. A well-chosen specification should balance puncture resistance, seal quality and easy tying so nurses, technicians and cleaning staff do not lose time with failed bags or messy spillages. The proper grade gives cleaner handling and less incident risk on the floor, which is where standards are judged.
Bubble bags can make a low-cost retail spectrum see more useful than it certainly is, because the product type promises protection even when the packaging itself is simple and cost-effective. In a shop setting, the main point is not the low price on the shelf, nevertheless whether the bag gives enough cushion for the kind of items likely to be packed into it. Thin bubble can crush down below weight, and poor seal quality can let the bubbles lose performance if the bag is handled roughly in storage or dispatch. A bargain spectrum may still work well for light products, nevertheless it requirements transparent limits. If the bag is matched to the proper job, it can sell through cleanly without creating complaints later.
Printed carrier bags & retail packaging
Printed carrier bags rely on the all converting process being balanced, not only on attractive artwork. A crisp design still causes trouble if the film gauge is also light or the web tension is unstable, because the print can transport out of register and the bag may stretch in the gross places. That often shows up later as weak seals, distorted panels or handles that give method when the bag is filled. A proper dash with the proper slip and proper control on the machine retains the stop consistent and the bag easier to handle through packing and dispatch.

If curing, slitting and seal settings are pushed also hard, tolerance soon shows up as scuffed print or weak side seams. Consistent stock widths and a sensible mono-material build make the dash steadier and leave the finished bag easier to recycle.
A carrier bag has to survive far above the brief walk from counter to car, so the material and gauge need to suit the load as well as the see. Thin film may fold neatly and take print well, nevertheless it can split or distort if the contents are awkward, while a heavier bag gives better confidence in handling and stacking. Handle style matters also, because a cut-out or looped handle changes how the weight sits in the hand and how the bag behaves in transit. When the proper structure is chosen, the bag carries products cleanly and avoids complaint at the point of use.
United Kingdom's Central Retail bags two leading awards
A well-manufactured retail bag has to balance strength, appearance and handling, because a bag that fails at the till creates more trouble than it solves. A light gauge can save material, nevertheless if the film is also weak it tears when packed tightly, dragged across a counter or carried with a mix of hard-edged items. That leads to spills, complaints and wasted stock. A sensible specification gives enough transport strength without pushing the weight of the bag higher than needed, so production stays efficient and the finished item still feels tidy in the client's hand. The optimal retail bag is the one that acquires through the shop without inviting attention.
Display bags for greetings cards need a close size match because loose packing quickly shows in both the packing room and on the shelf. When there is also much spare space, the card and envelope slide around inside the bag, and that movement soon labels corners, shifts the contents off-square and leaves the front looking untidy after picking or boxing. A better fit grasps the pack in position, so it stays presentable through storage and secondary packing. It also speeds handling, since there is less fiddling about to acquire each pack lined up properly, which reduces wasted motion and damaged stock.

The proper value is not only speed nevertheless control: products can be opened again for counting or inspection without tearing up the pack, so stock checks are cleaner and less wasteful. If the bag is the proper size and the seal bites properly, the result is tidy handling and less lost parts at the point of use.
Plain polythene suppliers bags perform optimal when the film is matched properly to the product and the packing line, because gauge and seal quality determine whether the bag runs cleanly or causes stoppages. Too light a film can split amid filling, stacking or dispatch, while an above-specified bag adds material cost and creates more waste than the load in reality requirements. In plenty warehouses, the transparent stop also assists staff identify products quickly at the select face, which saves time and reduces mistakes. A bag that balances strength with low weight normally makes the rest of the operation dash more smoothly.
