The most widespread shrink wrap film is low density polyethylene, more commonly referred to as polythene or PE. The principal use to which PE is put is as a transit medium. It allows packs to be wrapped individually or collated and offers the best combination of protection and unit cost when compared with the alternatives.
PE shrink wrap packaging film is used on a vast range of products, from radiators and work surfaces to collation of cans and jars and the individual shrink packaging of cartons and products themselves, such as pizza. Shrink wrap plastic applications do have overlap between transit and display shrink film where there is a requirement for the enhanced presentation offered by display, and equally, where the advantages of display are not required.
The shrink wrap plastic ranges do not overlap totally as a fundamental transit requirement in the normal way can be satisfied only by PE shrink wrap film.
