RFH 355nm UV Nanosecond Laser Cold Processed Food Packaging PE Film Bag   PE film, also known as polyethylene film, is usually thin and soft in texture, and can generally be used for wrapping films that are close to articles, such as mucous membranes, shrink films, protective films, etc. PE film is also commonly used in food packaging. As we all know, the food law stipulates that a lot of necessary information must be displayed on food packaging, which requires a special laser to complete the marking process on this material.
