The transparent plastic packaging box will be covered with a thin layer of adhesive tape. The main function is to prevent scratches and abrasion on the surface of the plastic box. In the course of slicing, the plastic box will be covered with film at the same time. After the film covered with one sheet of film is processed at the back, it will go through several links, such as beer, printing and hot dyeing, and each link will be rubbed by the machine. Therefore, The film on the surface of the plastic box can play a very good protection at this time.

The protective film of the plastic box is not the same as that of the paper product. The paper product is coated on the plastic film by a roller coating device, heated by a hot-pressing roller to soften the film, and then coated. The printed material of the primer and the film are pressed together to form a film-plastic-laminated film product. The raw material of the plastic box is the film. The most original state of the film is a roll. During the process of opening the material, it is heated and rolled to make it smooth. During the rolling process, the film will cover the surface of the film at the same time. . This is the same principle as film wrapping.

PET plastic box, PVC plastic box The most common transparent plastic box, in the later printing, hot, beer, dip process can play a role in blocking the machine. If it is in the printed plastic box, but also cover a special electrostatic film. Because of its molecular structure and some added ingredients, the film absorbs static electricity in nature. Especially the PVC film, the surface of the electrostatic value is very large, the human hand will be touched above. This kind of film with static electricity cannot be printed normally. Therefore, UV printing must be coated with antistatic film. This is also the difference between plastic boxes and other packaging products.
