Polyethylene is widely used in the production of various plastic appliances used in the kitchen and food industries. LDPE is used in the production of lightweight plastic containers as well as plastic bags. HDPE is used in the production of milk and liquid containers and all kinds of plastic kitchen utensils. MDPE is commonly used in the production of pipes and piping fittings.
LLDPE is used in the production of flexible plastic devices such as bendable pipes due to its high degree of flexibility. Recently, many researches have been done in the production of polyethylenes with long chains and short branches. These polyethylenes are originally HDPE with a number of side branches. These polyethylenes have a combination of HDPE strength and LDPE flexibility.
