NOVELTY - The bag has an upper part and an inner layer provided with multiple small holes. The inner layer and an outer layer are provided with an anti-corrosive layer. The inner layer is made of graphene material, and the outer layer is made of plastic. The inner layer and the anticorrosive layer are compounded together by a soft white latex using a preservative i.e. sodium benzoate. USE - Food packaging bag. ADVANTAGE - The bag reduces the contact area of the food preservative and food, thus preventing the preservative food safety problem. The graphene is provided with antibacterial effect, thus increasing the food safety. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a food packaging bag.
