Linear low density polyethylene (abbreviation: LLDPE)

Linear low-density polyethylene (LLDPE) is a molecular structure in which ethylene is copolymerized with a small amount of α-olefin to form a linear ethylene main chain with very short comonomer branches.

Linear low-density polyethylene is non-toxic, tasteless and odorless milky white particles with a density of 0.918-0.935g/cm³. Compared with LDPE, it has a higher softening temperature and melting temperature, and has the advantages of high strength, good toughness, rigidity, heat resistance, and cold resistance. It also has good resistance to environmental stress cracking, impact strength, and resistance to cold. It has excellent tear strength and other properties, and is resistant to acids, alkali, organic solvents, etc. and is widely used in fields such as industry, agriculture, medicine, health and daily necessities.
