Process for preparing composite transfer straightly plated cardboard

Abstract

A method for preparing composite transfer direct-plating cardboard, comprising the following steps in sequence: (1) providing a film with a corona value on the surface to be treated within the range of 30-46 dynes; (2) forming a film on the surface to be treated (3) make the one side of the coating layer of the film and the side of the cardboard composite; (4) peel off the film to obtain dry transfer cardboard; (5) coat the obtained transfer cardboard Aluminum plated on the layer. In a preferred embodiment, the preparation method of the composite transfer direct-coated cardboard further includes the step of performing laser holographic embossing treatment on the surface of the film to be treated before the step (2). In another preferred embodiment, the preparation method of the composite transfer direct-coating cardboard further includes step (6) coating a second paint on the obtained aluminum-coated layer to form a protective layer. Compared with the prior art, the present invention has the advantages of simple steps, convenient operation, suitability for large-scale production, high product quality and cost reduction.

Description

technical field [0001] The invention relates to a packaging and printing material, more specifically, to a method for preparing composite transfer direct-plating cardboard. Background technique [0002] Due to the fact that the traditional aluminum composite cardboard itself cannot degrade itself, and it is easy to leave harmful substances, it does not meet the requirements of environmental protection. At present, the materials used for daily necessities such as tobacco, tea, wine, and cosmetics in the packaging and printing industries are transitioning to environmentally friendly products. And the technology is in the development stage. [0003] The production methods of traditional aluminum composite cardboard include two methods: direct plating method or transfer method. The direct plating method is to directly coat a paint layer on one surface of the cardboard to form a mirror surface, and then directly coat aluminum on the paint layer to form a mirror surface. The alum...

Problems solved by technology

For the direct plating method, its advantage is that no film is required, so the cost is low and the process is simple; its disadvantage is that not only the requirements for paper are high during production, but also the mirror effect of its products is poor.

For the transfer method, its advantage is that the requirements for paper are not high during production, and its product has a good mirror effect; its disadvantage is that its production process is more and the cost is higher.
