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.
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 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.
