LDPE is the oldest and most mature of the polyethylenes (PE). It is characterised by its short and long chain branching which gives it good clarity and processability although it does not have the strength properties of the other PEs. The largest outlet for LDPE is the film market, accounting for around 55% of global consumption and used mainly in food and non-food packaging. Food packaging applications include dairy products, snacks and sweets, frozen food bags and baked goods. It is used where high clarity films are required such as produce bags and bakery film.
