Pearl cotton is a new type of environmentally friendly packaging material. It is composed of low-density polyethylene grease through physical foaming to generate numerous independent bubbles. It overcomes the shortcomings of ordinary styrofoam, such as fragility, deformation and poor recovery. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat insulation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc., and also has good chemical resistance. It is an ideal substitute for traditional packaging materials.
