【summary】

As the application field of lasers continues to expand, the application of lasers in the film packaging industry continues to improve, and laser processing has become a new technical standard in the PE, PVC, and PET film processing industries.

Problem of easy tearing in conventional dotted line knife processing

The traditional processing method for easy tearing on film is to use dotted line knife processing. When the film is processed with easy tearing lines, the film is punched with a manually controlled blade. Due to different operations of the operators, the cross-section of the easy tearing lines after processing is large, the overall flatness of the easy tearing lines is different, the easy tearing lines are easy to break, the product qualification rate is low, and it is easy to affect subsequent operations. In addition, the blades and the pressure rollers used in the processing are easy to be damaged. Basically, the blades and pressure rollers are discarded within one month, the production cost and the workload are increased, the processing efficiency of easy tearing is low, and the work intensity is high.
