LLDPE raw materials

Product Introduction
LLDPE is a thermoplastic polyolefin resin obtained by low-pressure copolymerization of ethylene and α -olefins (butene/hexene/octene). It appears as semi-transparent milky white granules and has a linear short branched structure. It can be processed through casting, blown film, injection molding, and rotational molding. It is a core raw material in the film field and the preferred base material for producing stretch films.

Product Details

Core Features

  1. High puncture resistance, high tear strength, excellent tensile elongation, the toughness is far superior to ordinary LDPE, which can reduce the thickness of the film without reducing the load-bearing capacity

  2. Outstanding low-temperature resistance, not easy to crack at low temperatures, suitable for cold chain, winter outdoor packaging and agricultural film

  3. Good resistance to environmental stress cracking ESCR performance, acid and alkali resistance, chemical corrosion resistance, moisture and water resistance

  4. Excellent heat sealing performance, The heat sealing layer is strong, and the heat sealing is not easy to break

  5. Stable melt performance, film grade grades are suitable for casting/blowing films; injection molding/rotational molding grades have adjustable fluidity

  6. Non-toxic and tasteless, can be used in food contact products, can be recycled

Tips: LLDPE melt viscosity is high, pure material processing extrusion pressure is large, film production often a small amount of LDPE blended to improve processing fluidity

Major applications

  • Membranes (most mainstream): traysStretch Wrap, heavy packaging bags, food packaging film, greenhouse agricultural film, geomembrane, lining bags

  • Injection molding: plastic containers, plastic buckets, lids, toys, hoses

  • Rotomolding: large storage tanks, water tanks, outdoor large plastic components

  • Extrusion: Insulated sheath for wires and cables
