Linear low-density polyethylene (LLDPE) is a molecular structure formed by copolymerization of ethylene and a small amount of α-olefin on the main chain of linear ethylene with very short comonomer side chains.

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

Product use

LLDPE has penetrated most traditional markets for polyethylene, including film, molding, pipes and wires and cables. Leakage-proof ground film is a newly developed LLDPE market. Ground film, a large extruded sheet, is used as a liner for waste landfills and waste pools to prevent leakage or pollution of surrounding areas.

Some LLDPE film markets, such as the production of bags, trash bags, elastic packaging, industrial liners, towel liners and shopping bags, all take advantage of the improved strength and toughness of this resin.
