Description

Technical Field

[0001] The utility model relates to the technical field of cross - film processing equipment, in particular to a scar - removing device for cross - films. Background Art

[0002] The cross - film used for rice bags is a special composite film for rice packaging. It is usually formed by cross - laminating multiple layers of films with different materials through a special process. Generally, it includes the following common structural layers: the outer layer, usually made of high - strength materials such as polyester (PET), etc., has good wear resistance, puncture resistance and printing adaptability, can protect the internal structure and facilitate printing product information; the middle layer, mostly made of materials with good barrier properties such as polyvinyl alcohol (PVA), ethylene - vinyl alcohol copolymer (EVOH), etc., can effectively block oxygen, water vapor and odor, etc., prevent rice from getting damp, oxidized and contaminated, thus extending the shelf life of rice; the inner layer, generally made of materials with good heat - sealing properties such as polyethylene (PE), etc., ensures the sealing of the rice bag and prevents rice leakage.

[0003] Now in the production of cross - films, the cross - lines (crease marks) on both sides after lamination have always been relatively obvious. The cross - lines may form obvious patterns or defects on the surface of the film. These patterns may be caused by uneven distribution of cross - lines, tension changes during the production process or other factors. The patterns and defects will affect the appearance quality of the film, making the packaging look less smooth and tidy. For example, during the printing process of the cross - film for rice bags, the patterns may cause unclear or blurred printing patterns, affecting the aesthetics of the rice bag.
