　　Polyethylene foam cotton is a non crosslinked closed cell structure, also known as EPE pearl cotton. It is a new type of packaging material. It is composed of many independent bubbles produced by physical foaming of low-density polyethylene grease. It overcomes the shortcomings of fragile, deformation and poor recovery of general styrofoam.

　　It has many advantages, such as water-proof, moisture-proof, shockproof, sound insulation, thermal insulation, good plasticity, strong tolerance, recycling, strong collision resistance, etc. it also has good chemical resistance. It is an aspirational substitute for traditional packaging materials.

　　Extended data:

　　The primary application fields of LLDPE are agricultural film, packaging film, wire and cable, pipe, coating products, etc.

　　Linear low density polyethylene is mainly used to make films because of its high tensile strength, good puncture and tear resistance. In 2005, the world LLDPE consumption was 16.17 million tons, a year-on-year increase of 6.4%.

　　In the consumption structure, film products still account for a large proportion, with a consumption of 11.9 million tons, accounting for 73.6% of the total consumption, followed by injection molding, with a consumption of 1.148 million tons, accounting for about 7.1% of the total consumption of LLDPE.
