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.
