Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, and particularly relates to a cardboard film laminating device for food packaging box processing. Background Art

[0002] Cardboard film laminating is a common process used to improve the appearance and performance of cardboard. Film laminating can add gloss, water resistance, and abrasion resistance to the cardboard surface, and at the same time enhance the tear resistance and durability of the cardboard. Film laminating is usually carried out using a special film laminating machine, which evenly coats a layer of film (such as polyethylene, polypropylene, etc.) or coating on the cardboard surface.

[0003] Before laminating the cardboard, dust in the air is likely to adhere to the surface of the cardboard. If directly laminated, there will be dust between the film and the cardboard, which will affect the aesthetics of the laminated cardboard and also the connection stability between the subsequent cardboard and the film.

[0004] Therefore, a cardboard film laminating device for food packaging box processing is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cardboard film laminating device for food packaging box processing to solve the problems raised in the above background art.
