Method for compounding metal membrane by transfer-type film as well as production equipment thereof

Abstract

The invention relates to a method for compounding a metal membrane by a transfer-type film as well as production equipment thereof. The method comprises the following steps: pretreating the surface of a plastic film; coating mucilage on the surface of a metal layer on a carrier film; drying up the carrier film; precooling the carrier film; compounding the plastic film and the carrier film by a lamination mode; carrying out hot-pressing and drying; stripping a base material layer of the carrier film. The mucilage is coated on the carrier film and is compounded with the plastic film, and finally the base material layer of the carrier film is stripped off, so that the original surface of the metal layer of the carrier film is attached to the plastic film by the mucilage, and the surface of the metal layer, which is attached to the base material layer, is converted into the surface of a metal compound film. The surface of the metal compound film after being compounded is provided with an even mirror surface, and has high metallic luster; the metal film is compounded by a transfer mode without being performed at high-temperature environments; the plastic film cannot be deformed, and the waste rate of the plastic film is reduced to be less than 0.5%; the finished product rate of the metal compound film is improved greatly.

Description

technical field [0001] The invention relates to a film compounding method and equipment, in particular to a transfer type film compounding metal film method and production equipment thereof. Background technique [0002] Plastic film (such as PE film) is soft and comfortable, has good tensile and elongation properties, and is breathable and impervious to water. As a packaging film, it can protect the product from pollution, corrosion, and scratches during production, processing, transportation, storage, and use. It is the most widely used polymer packaging material in the world today. In my country, with the gradual improvement of people's living consumption level, food, medical and other industry regulations have been continuously established and improved, and the application range of plastic films has been continuously expanded, maintaining a growth rate slightly higher than domestic GDP for many years. At present, my country's plastic film consumption level is 108g / perso...

Problems solved by technology

However, the traditional metal texture production process of the plastic film surface is backward, and the direct method of aluminum plating is generally used; and because the plastic is a non-polar material, the surface of the plastic film needs to be treated first to improve the adhesion with the coating before vacuum aluminum plating can be done. Or directly compounded with aluminum foil, due to the influence of high temperature, the plastic film is easy to deform, which affects the overprinting accuracy, the loss rate of raw materials is about 10%, and the yield rate is not high, resulting in high production costs; the product category is relatively single, mostly silver plastic film , it is difficult to meet user requirements
