AI Technical Summary

Problems solved by technology

Low-temperature lamination is to apply a layer of adhesive between the printed film and the steel strip on the surface, and to bond the printed film and the steel strip in a heated state; high-temperature lamination is to heat the steel strip through the preheating part of the electromagnetic induction heating roller to The temperature above the melting point of the film, using the extrusion of two symmetrical pressure rubber rollers to carry out the hot-melt lamination of the substrate and the film, it takes a lot of time to carry out the lamination and curing process when laminating, providing multi-effect gravure Printing coated iron roll film processing technology, so as to solve the above problems

Embodiment Construction

[0020] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Multi-effect gravure printing coated iron roll film processing technology, including PET substrate, processing steps:

[0022] (1) Firstly, conduct electric discharge treatment on the surface of the PET substrate, and remove the concave and convex positions on the surface of the PET substrate by the electric discharge treatment method;

[0023] (2) Then carry out gravure printing on the PET substrate with smooth surface treatment, and print the predetermined pattern on the surface of the PET substrate by gravure printing;

Abstract

The invention discloses a multi-effect intaglio printing laminated steel roll film processing process. A PET base material is included in the process. The process has the beneficial effects that the laminating speed is 5-10 times that of common tinplate printing, and the consumption of an organic solvent in the whole processing process is 1 / 3-1 / 4 that of tinplate printing; in addition, due to the combination with a flexible package material, besides the common printing effect, different appearance effects such as laser, aluminizing, and glowing are added to the laminated steel; and in addition, the anti-counterfeiting requirements are met by adding variable bar codes, two-dimensional codes and the like to the laminated steel.

Description

technical field [0001] The invention discloses a multi-effect gravure printing film-coated iron roll film processing technology, which belongs to the technical field of film-coated iron roll film. Background technique [0002] Laminated iron uses high-performance polyester film instead of TFS epoxy resin coating, which has stronger anti-rust and anti-corrosion properties, which is beneficial to long-term storage of food without affecting the taste and quality; compared with coated tinplate, the cost is lower and completely eliminates The pollution and residues caused by printing and coating are currently the most environmentally friendly can making materials in the world. [0003] At present, there are two main processing methods of coated iron commonly used, low temperature pressing and high temperature pressing. Low-temperature lamination is to apply a layer of adhesive between the printed film and the steel strip on the surface, and to bond the printed film and the steel...
