Problems solved by technology

[0002] Pearl cotton (also known as EPE) is a new type of environmentally friendly packaging material. It is composed of low-density polyethylene fat through physical foaming to produce countless independent bubbles, which overcomes the shortcomings of ordinary foaming rubber such as fragility, deformation, and poor recovery.
It has many advantages such as water and moisture proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc. It also has good chemical resistance, but the current polyethylene foam material still has bending Insufficient strength, elasticity and heat resistance limit its application
