Cold chain storage bag with Qi the highest density of 1680D double fabric made of polyester. Resistant to dirt, waterproof, high gloss, long service life. Ordinary refrigerator is usually used as ordinary cloth lining inside the refrigerator, ice Qi medical environmental protection silver aluminum film, can effectively reflect air molecules, makes the air distribution within the package is more uniform.
The heat insulation layer of cold storage bag is high density EPE material. Cold chain vaccine cold packs can be customized according to customer requirements of the corresponding density, thickness of the cold bag. Different density, different thickness of the insulation layer will affect the length of cold preservation time.
