Polyethylene film is a plastic film made from ethylene, a hydrocarbon which is mainly obtained from natural gas or petroleum. The terms 'plastic sheeting', 'polyethylene sheet', 'poly sheeting' or 'poly film' are often used as synonyms for polyethylene film.
High Density Polyethylene Film is a common packaging material made to protect food and food material.
LDPE film is heat sealable, chemically inert, odour free and shrinks when heated. It is a good moisture barrier but has relatively high gas permeability, sensitivity to oils and poor odour resistance. Low-slip properties can be introduced for safe stacking, or conversely high-slip properties permit easy filling of packs into an outer container. It is less expensive than most films and is therefore widely used for pouches, bags, coating papers or boards and as a component in laminates.
