There’re 3 types of material for cushion air pillow, HDPE, LDPE and biodegradable material. HDPE is the most common type of the air cushion film, it has competitive price. But the air in it can only keep for 7-10 days, and will leak slowly after that. So this decides that HDPE material can only use in short-term transportation.
The air will keep longer for LDPE, normally 1-12 months depending on the thickness. So it’s more suitable for long-term transportation.
As for biodegradable of cushion air pillow, its resistance to compression will be a little weaker than HDPE or LDPE, due to non chemical formula in it. But it can afford normal compression in the packaging, it’s also a good choice for cushion air pillow as it’s environmentally friendly.
Cushion air pillow as one of most popular protective material in the market, it’s not only good for void filling, but also good for small items protective, such as small cosmetics, fruit, tool kits, etc. The air pillow bag is also used together with air bubble wrap or four rows pillow rolls. Use them together in the packaging, will be good to wrap and fix the goods in the box, reduce collisions, and protect the goods well.
