Polyethylene foam cotton is a non crosslinked closed cell structure, also known as EPE pearl cotton, which is a new environmentally friendly packaging material. It is composed of countless independent bubbles generated by physical foaming of low-density polyethylene grease. Overcoming the shortcomings of ordinary foam adhesive such as fragility, deformation, and poor recovery. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, thermal insulation, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance. It also has good chemical resistance. It is an ideal substitute for traditional packaging materials.
