▎ 摘 要
NOVELTY - A food packaging bag comprises outer layer (1) and an inner layer (2), where the inner layer is graphene antibacterial layer, the graphene antibacterial layer is provided with a small hole (3), the outer layer is a plastic layer, and the inner layer and the outer layer is provided with preservative (4). The edge of the inner layer and the outer layer are compounded together by soft white latex. The inner layer and the outer layer is 2 mm. USE - As a food packaging bag (claimed), used in packaging material. ADVANTAGE - The food packaging bag reduces the contact area of the food preservative and food, thus exhibits anticorrosion property; also reduces content of preservative in food, which prevents the preservative caused by food safety problem; and increases the food safety. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of the food packaging bag. Outer layer (1) Inner layer (2) Small hole (3) Preservative (4)
