What are the benefits of packaging sponges?
Some introduction to packaging sponge: excellent heat resistance of packaging sponge: the foaming corner is usually used under 80t, the foaming Px instrument is capable of 70-80 ℃, and the foaming PP is capable of 120t. The size of foamed PP is shortened by less than 2% after being placed at 120 ℃ for 21h, and that of foamed PE is shortened by about 40% under the same conditions. Therefore, foamed PP can be used in applications where the application temperature exceeds 100t.
Packaging sponge with excellent mechanical functions: Take Ace EVA foam material of Kogawa Electric Company in Japan as an example. Its mechanical functions such as tensile strength and tear strength are at the highest level of foam plastic; Its compressive strength is lower than that of hard PUR and foamed Ps. It is higher than that of soft PUR, which means it has medium compressive strength; The packaging sponge has obvious heat insulation property: foamed PP and foamed PE are of closed cell structure, so their thermal conductivity will not be affected by solid moisture. Because their thermal conductivity is lower than that of foamed PE, they have obvious heat insulation property, so they can be used as advanced thermal insulation materials.
Packaging sponge benefits
Packaging sponges have many special classifications, but also many advantages. For example, packaging sponges with resilience have high impact energy absorption capacity.
The chemical corrosion resistance of packaging sponge is better than that of all other foam plastics; It is resistant to edible oil and meets the demand of greasy food packaging.
The packing sponge has good stress cracking resistance.
Compared with foamed PS, foamed PP in packaging sponge does not emit toxic gas during incineration.
