Problems solved by technology

[0002] Aluminum can packaging is widely used in the packaging of beverages and food due to its light weight, beautiful appearance, and easy processing and molding. However, aluminum packaging also has disadvantages. Aluminum elements react with certain chemical substances in food to form aluminum ions that enter the human body Excessive consumption of aluminum ions will cause osteoporosis, immune function decline and other hazards to the human body.

Embodiment Construction

[0013] A double-sided roll-coated aluminum coil for food packaging, comprising an aluminum base layer 1, a chemical layer 2, a primer layer 3, a topcoat layer 4, a chemical layer 5, a primer layer 6, a sealing film layer 7, Silver ion antibacterial film layer 8; the top surface of the aluminum base layer 1 is connected with the chemical layer one 2, the primer layer one 3, and the top coat layer 4 successively; the bottom surface of the aluminum base layer 1 is sequentially connected with the chemical layer two 5, the primer layer 2. 6. The sealing film layer 7 and the silver ion antibacterial film layer 8 are connected. The sealing film layer 7 is a thin film added with a sealing agent, which can effectively block the reaction between the aluminum element and the food, and simultaneously the sealing film layer 7 can effectively prevent the silver ion from reacting with the aluminum element and weaken the antibacterial strength; the silver ion antibacterial film layer is set 8...

Abstract

The invention provides a double-side-roller-coated aluminum coil for food package. The double-side-roller-coated aluminum coil comprises an aluminum base layer, a chemical layer I, a primer layer I, afinishing coat layer, a chemical layer II, a primer layer II, a close membrane layer and a silver ion bacteriostatic membrane layer, wherein the top surface of the aluminum base layer is successivelyconnected with the chemical layer I, the primer layer I and the finishing coat layer; and the bottom surface of the aluminum base layer is successively connected with the chemical layer II, the primer layer II, the close membrane layer and the silver ion bacteriostatic membrane layer. The aluminum coil of the invention can be directly used for packaging of food cans and the like, has the advantages of uniform membrane thickness, strong corrosion resistance and strong bacteriostatic ability, and is capable of preventing people from harm caused by reactions of aluminum ions with food.

Description

technical field [0001] The invention relates to the field of roll-coated aluminum coils, in particular to a double-sided roll-coated aluminum coil for food packaging. Background technique [0002] Aluminum can packaging is widely used in the packaging of beverages and food due to its light weight, beautiful appearance, and easy processing and molding. However, aluminum packaging also has disadvantages. Aluminum elements react with certain chemical substances in food to form aluminum ions that enter the human body Excessive consumption of aluminum ions will cause osteoporosis, decreased immune function and other hazards to the human body. Contents of the invention [0003] In order to solve the above technical problems and provide a raw material for the preparation of aluminum cans that can prevent aluminum ions from reacting with food and has a good antibacterial effect, the invention provides the following technical solutions: [0004] A double-sided roll-coated aluminum...
