Aluminum Foil Roll for Warpping
In order to solve the problems that the packaging material does not have the sterilization function or the antibacterial layer is easy to fall off, causing bacteria to invade the food or medicine, causing the food or medicine to deteriorate and affect health, this article provides an antibacterial aluminum foil composite material and a manufacturing method thereof.
In order to achieve the above object, the technical solution adopted by the present invention is: an antibacterial aluminum foil composite material, the composite material includes a plastic film and an aluminum foil, the plastic film and the aluminum foil are connected to each other by an adhesive, and the surface of the aluminum foil is provided with The antibacterial aluminum film layer is provided with an antibacterial agent.
Further, the material of the plastic film is PE, PP or PET, the thickness of the plastic film is 0.03-2mm, and it needs to be compounded with aluminum foil
Further, the adhesive is polyurethane, and its thickness is between 0.005-0.01 mm.
Further, the thickness of the aluminum foil is 0.0055-0.03 mm.
Further, the antibacterial agent is made of any combination of antibacterial metals including silver, silver oxide, copper or copper oxide.
A method for manufacturing an antibacterial aluminum foil composite material. The steps for manufacturing the above antibacterial aluminum foil composite material are as follows:
1) Apply a layer of adhesive to the surface of the base plastic film;
2) The aluminum foil is bonded to the surface of the plastic film by thermocompression;
3) Using the composite material in step 2 as an anode, put it into an electrolyte solution for oxidation reaction, and a porous alumina film is prepared on the surface of the aluminum foil;
4) Using the aluminum foil composite material with the porous alumina film prepared in step 3 as the cathode, put the electrolyte solution into the electrolyte solution for coloring and deposition reaction, so that the antibacterial metal is electrolytically deposited in the pores of the porous alumina film to obtain the antibacterial aluminum foil composite material;
