What material is pearl cotton made from?

Add: 2020-03-26Click:
With the rapid development of logistics industry in our country in recent years, pearl cotton packing material is more familiar, in simple terms, pearl quilt is widely used in car cushion, pillow, electronic appliances, instruments and meters, computer, medical equipment, hardware, lighting, furniture, furniture and other products packaging, so, pearl cotton packing material which good? By the way, do you know what material pearl cotton is made from? The following is Shared by the staff of the dry packaging for us:

What material is pearl cotton made from?

1. Compared with ordinary packaging materials, pearl cotton packaging materials not only have higher density, better elasticity and resilience, more delicate surface, and are not easy to deform.

2. Pearl cotton packaging material is a new type of environment-friendly packaging material, which is composed of numerous independent bubbles generated by the physical foaming of low density polyethylene grease. It overcomes the defects of common foam, such as fragile, deformation and poor recovery. It has many advantages such as waterproof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance and so on. It is an ideal substitute for traditional packing materials.

3. Shockproof packaging of pearl cotton is made by physical foaming. The choice of foaming auxiliary agent, shrinkage agent and nucleating agent and the temperature control requirements are relatively severe. When choosing foam agent, requirements in the condition of scale into gas, convenient liquefaction under pressurized conditions, the second is for foaming agent is a colorless, odorless, non-toxic, no corruption 鉵 sex, foaming leave no residue in the polymer, low in polyethylene melt infiltration excretion rate, low steam at room temperature, high volatile and low molecular weight and density is big, the unit volume of gas capital is low, the extrusion condition can dissolve in polyethylene, elevated temperature and pressure, dissolved quantity change increases, easy to make the foam molding for foam density is small.

From the above description, we can know what material pearl cotton is made of. In addition, the pearl cotton packing material also has the independent bubble and the fine bubble structure, makes the pearl cotton packing material has the high elasticity, and is rich in the toughness but not the crisp, is the world's better protective inner packing material.
