Printing film-laminated metal plate and production method thereof

Abstract

The invention provides a printing film-laminated metal plate and a production method thereof. The printing film-laminated metal plate comprises a metal substrate, a printing composite film and an inner film, wherein the metal substrate is positioned between the printing composite film and the inner film so as to form no-adhesive attachment; the printing composite film is formed by dry composition between an intaglio-printing film and a polyester film modified by isophthalic acid; one side of the intaglio-printing film with printing patterns is attached with the acid-modified polyester film, and one side of the intaglio-printing film attached with the metal substrate is the acid-modified polyester film; and the inner film is made of no-printing-pattern film or intaglio-printing film, and one side of the intaglio-printing film with the printing patterns is attached with the metal substrate. The invention also provides the production method of the printing film-laminated metal plate. The printing film-laminated metal plate provided by the invention has the advantages that the printed patterns are sealed between the film and the metal substrate, so that the safety of the printing film-laminated metal plate is obviously improved and the processing process is simplified.

Description

technical field [0001] The invention relates to material technology, in particular to a printed film-coated metal plate and a production method thereof. Background technique [0002] Metal packaging is an important part of China's packaging industry, mainly providing packaging services for food, canned food, beverage, oil, chemical, pharmaceutical and other industries. At present in our country, most of the food packaging is coated with iron. With the development of technology, metal coating technology is gradually replacing the traditional packaging with its absolute advantages in performance, cost, environmental protection, energy consumption, chemical stability, etc. Paint iron. [0003] Metal coating technology was born in Japan in 1977. It was originally used in cans, which can replace internal and external coating technologies. Up to now, it has been developed into various fields such as building materials, interior and exterior decoration, home appliances, and automo...

AI Technical Summary

Problems solved by technology

The processing technology of this kind of printing coated metal plate actually uses the coated metal plate as the printing carrier, and the requirements for the printing method change. Not only is it prone to the problem of poor printing quality, but the coated metal plate is also There is a defect of low printing resistance, which will have higher requirements for printing technology. At the same time, from the perspective of safety, it is also necessary to consider adding a protective layer outside the printing layer, which also leads to complicated processes.

On the other hand, there will be VOC emissions in both the printing process and the later use process, and the user needs to directly contact the ink and protective layer of the printing layer, or even directly contact with the mouth, resulting in the migration of chemical substances and causing harm to the human body
