Production technology of corrugated board with two film-coated surfaces

Abstract

The invention provides a production technology of a corrugated board with two film-coated surfaces, and belongs to the technical field of cardboard processing. The technology comprises the following steps: (1) printing patterns on OPP films; (2) laminating the printed OPP films on the top surface and bottom surface of a corrugated board; (3) pre-heating the corrugated board with laminated OPP films, and finally moulding the corrugated board in a moulding machine to obtain the corrugated board with two film-coated surfaces. The invention further provides a corrugated board with two film-coated surfaces, which is produced by the provided production technology. The production technology has the advantages of high production efficiency, low production cost, and simple technology, and can achieve film-coating and printing on two surfaces of a corrugated board. The surface of the printed patterns cannot be easily scratch or damaged, and the pre-heating effect is good. The produced corrugated board with two film-coated surfaces has a good dampproof and wear-resistant performance, and can be applied to refrigeration of high-end seafood and dairy products. The corrugated board will not absorb water and become soft in the refrigeration house, so the corrugated board is suitable for being used in the cold-chain transportation or storage.

Description

technical field [0001] The invention relates to the technical field of cardboard processing, in particular to a production process of double-sided peritoneal corrugated cardboard. Background technique [0002] Packaging boxes made of corrugated cardboard are widely used in various fields of life and industry. The production process of traditional corrugated boxes is generally through single-sheet paper printing, single-sheet paper OOP peritoneum, corrugated cardboard production, surface paper and corrugated cardboard lamination, die-cutting, creasing, slotting, box gluing, and nailing. However, the corrugated cardboard is a single-sided peritoneal cardboard, which has poor moisture-proof and abrasion resistance, low compressive and bursting strength, and due to the structural characteristics of the single-sided peritoneum, there are certain limitations in the use of the produced packaging boxes, such as Some dairy products and high-end seafood will be damp and softened in c...

Problems solved by technology

However, the corrugated cardboard is a single-sided peritoneal cardboard, which has poor moisture-proof and abrasion resistance, low compressive and bursting strength, and due to the structural characteristics of the single-sided peritoneum, there are certain limitations in the use of the produced packaging boxes, such as Some dairy products and high-end seafood will become damp and soft in the cold storage and cold storage, making the entire packaging box invalid, so it is not suitable for the use of cold chain product packaging

[0003] Traditional corrugated cardboard is printed and printed on a single sheet of paper according to customer needs before processing. This method can only achieve single-sided printing and single-sided printing of the cardboard, and it is easy to cause scratches and damage to the surface of the printed pattern. Traditional The production efficiency of the process is low, the production cost is high, and the process is complicated. It can only produce corrugated cardboard with single-sided peritoneum and single-sided printing
