Linear Low Density Polyethylene, abbreviated as LLDPE. Linear low-density polyethylene (LLDPE) is non-toxic, tasteless, 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, high rigidity, heat resistance, and cold resistance. It also has good resistance to environmental stress cracking, impact strength, tear strength, etc., and is resistant to acids, alkalis, and organic solvents, and is widely used in industries, agriculture, medicine, hygiene, and daily necessities.
