LDPE is a polyethylene with lower density. It is the most frequently used material in the production of foils, in particular for packaging. All simple types of disposable bags, garbage bags, and shopping bags are made just from LDPE. The reason is particularly its low price and easy processing ability.
Foils are manufactured by extrusion, either as 2D foils or hoses (tubular extrusion). Foils can be made as very thin (bags for baked goods) or thick-walled (large bags). Package thickness may be adapted to application requirements from 30 micrometers (0.030 mm) up to 200 micrometers.
Should the final package be resistant against perforation, PE foils may be laminated with another foil type improving features of the final package. For example, lamination with PET foil (polyethylene-terephthalate) is used in the production of foodstuff bags for pets. Lamination with a paperboard is applied in the production of juice packages (Tetrapack type).
The benefit of LDPE is that it can be imprinted very well. Shopping bags and large bags can be decorated with multi-colour print. This material can also be welded to achieve various shapes of pouches and bags. Recycled PE may be returned back for the production of pouches and bags, which saves the environment.
