Color printing lamination metal plate and preparation method thereof

Abstract

The invention provides a color printing lamination metal plate and a preparation method thereof. The color printing lamination metal plate comprises a metal substrate and a color film adhered to at least one side surface of the metal substrate in an adhesive-free way; the color film is a relief block film; and the one side of the color film adhered to the metal substrate has color patterns. The color printing lamination metal plate provided by the invention contains no adhesive, and the color patterns of the printing film are sealed between the film and the metal substrate, so as to significantly improve the safety quality of the color printing metal plate; and the preparation method of the color printing lamination metal plate does not cause tensile deformation of the color printing patterns in a lamination process, and no adhesive is used to adhere the color printing film to the metal substrate.

Description

technical field

[0001] The invention relates to a film-coated metal plate and a preparation method thereof, in particular to a color-printed film-coated metal plate and a preparation method thereof. Background technique

[0002] With the rapid development of my country's economy, metal packaging materials, especially film-coated metal plates, occupy an important position in the packaging field due to their good airtightness, hard texture, good elasticity, good light-blocking properties, and good gas-barrier properties. As the process of preparing film-coated metal sheets (such as bonding method, melting method, etc.) matures day by day, people begin to study color-printed film-coated metal sheets with color graphic information and their preparation processes.

[0003] Existing color-printed film-coated metal plates are usually prepared by the bonding method. Although the temperature of this method is lower when the color-printed film is attached to the metal plate, the color...
