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 ...
