Problems solved by technology

Since the aluminum foil is often subjected to greater tension during rolling than subsequent processing, some of them only show poor shape during rolling, including incorrect roll grinding, incorrect roll shape, poor incoming material shape and incorrect shape adjustment.

Abstract

The invention discloses a technology for avoiding wrinkling occurring in aluminum foil intaglio printing. The technology includes the following steps that 1 corona treatment is conducted on the two sides of a PET film (1); 2 the corona surfaces of the two sides of the PET film (1) are coated with polyurethane composite adhesives, and aluminum foil (2 and 3) is stuck to the surfaces of the polyurethane composite adhesives; 3 one layer of silicone protective film (5) is stuck to the surface of the aluminum foil (2); 4 ink (4) is printed on the other surface of the aluminum foil (3) through an intaglio printing rubber device, and drying treatment is conducted on the ink; 5 the silicone protective film is removed. The technology can effectively avoid the situation that the surfaces of the aluminum foil wrinkle after the ink is printed on the aluminum foil through the intaglio printing rubber roller device, and the technology is simple, low in cost and suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of printing ink, in particular to a process for solving the wrinkling of aluminum foil caused by printing ink on the surface of the aluminum foil by adopting a gravure coating method. Background technique [0002] In recent years, aluminum foil composite materials have been widely used in food, medicine, aerospace and other fields due to their light weight, good airtightness, good wrapping performance, and environmental protection. It is especially used in electronic products such as mobile phones, computers, TVs, etc. to play a role in shielding and shielding. With the requirement of uniform appearance in electronic products, many aluminum-plastic composite materials need to be printed to have the same color as the structural parts. The gravure printing method is one of the commonly used printing methods. Because aluminum foil is brittle, it will form wrinkles when the aluminum foil is rolled up or unrolle...
