The bio-degradable edible and instant film developed by Wuhan University will hopefully become the nemesis of white pollution. The film is made of konjac as a raw material and transparent in whole body. It is an ideal bag for instant noodles seasoning, soymilk, oatmeal and other granules. It not only removes the pain of hand peeling, but also reduces white pollution. Its price is also 5% cheaper than plastic bags.
