Linear Low-Density Polyethylene, or LLDPE is very flexible, and possesses high impact strength. It makes a good barrier against both water and alcohol vapour and has excellent chemical resistance. It also has great stress crack and impact resistance.

LLDPE is most commonly used in the blow moulding creation of films. This is usually in food packaging, to help keep foods fresher for longer. It can also be used in producing agricultural films, clothing packaging, stretch film, and general-purpose films.
