1.Domestic equipment is small, single layer foam thickness is not enough;

2.Complex process, large amount of labor, high energy consumption; 3.Composite material is not high (compared with the density of single layer materials), a large waste of materials;

4.The traditional foaming process can not meet the needs of the current packaging area.

1.Single layer foam materials, high production efficiency, no artificial composite;

2.Single layer material has superior cushioning properties, and less material has better protective effect;

3.Can reduce the overall packaging costs.
