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

Embodiment 1

[0034] This embodiment provides a printed film-coated metal plate, which is formed by thermal bonding of two layers of PET film and metal substrate without adhesive. The enterprise's ink gravure printing has designed patterns (the "pattern" mentioned in the present invention should be understood as various design graphics and text content), the present invention is called the outer film; the inner PET film is unprinted Light film (transparent or opaque film can be selected according to requirements), this invention is called inner film. In this embodiment, both the inner film and the outer film are PET films with a thickness of 15 μm, and the metal substrate is a chrome-plated thin steel plate with a thickness of 0.12 mm. The total area accounts for 20% of the area of ​​the chrome-plated steel sheet.

[0035] The production method of the above-mentioned printed film-coated metal plate comprises the following steps:

[0036] 1) Using gravure printed PET film as the outer film...

Embodiment 2

[0047] This embodiment provides a printed film-coated metal plate, which is formed by heat-bonding two layers of PP film and metal substrate without adhesive, wherein the side where the inner layer of PP film and metal substrate are bonded is produced by DIC in advance The ink gravure printing of the enterprise has designed patterns (the "pattern" mentioned in the present invention should be understood as various design graphics and text content), which is called the inner film in the present invention; the PP film of the outer layer is unprinted Light film (transparent or opaque film can be selected according to requirements), this invention is called outer film. In this embodiment, both the inner film and the outer film are PP films with a thickness of 30 μm, the metal substrate is an aluminum plate with a thickness of 0.27 mm, and the side of the printed pattern of the inner PP film is corona treated, and the total printed pattern The area accounts for 35% of the aluminum p...

Embodiment 3

[0055] This embodiment provides a printed film-coated metal plate, which is formed by thermal bonding of two layers of PET film and metal substrate without adhesive. The pattern designed by the enterprise's ink gravure printing (the "pattern" mentioned in the present invention should be understood as various design graphics and text content), the present invention is called the outer film; the PET film of the inner layer is bonded to the metal substrate One side also has previously designed patterns and contents through gravure printing by Toyo Ink, which is called inner film in the present invention. In this embodiment, both the inner film and the outer film are PET films with a thickness of 20 μm, the metal substrate is a stainless steel plate with a thickness of 0.34 mm, and one side of the printed pattern of the outer and inner PET films is also corona treated. The total area of ​​the printed pattern on the outer layer and the inner layer both accounts for 45% of the area ...

Abstract

The invention provides a printing coated metal plate and a production method thereof. The printing coated metal plate comprises a metal substrate, an outer film and an inner film, wherein the metal substrate is positioned between the outer film and the inner film and are stuck to the outer film and the inner film without any adhesive; at least one of the outer film and the inner film is an intaglio printing film; and a printing pattern is formed on the side, stuck to the metal substrate, of the intaglio printing film. The invention also provides a production method of the printing coated metal plate. The printing coated metal plate is produced by the process that coating is performed after printing, and the printing pattern is sealed between the thin film and the metal substrate, so that the safety quality of the printing coated metal plate is obviously improved and the machining 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...
