Because the poor interface will cause quality problems such as broken film or wrinkle during the use of the film roll, which will cause a relatively bad impact on the user's use, the thin film interface must be operated in accordance with the regulations to ensure the bonding quality of the interface. The specific requirements are as follows:
1. Cut and flatten the two sections of the film of the joint horizontally, and paste it firmly on the front and back sides of the film;
2. In order to improve the quality of the interface, the film interface is required to be straight, balanced with the direction of the paper tube, and the interface is required to be flush without wavy, the interface at both ends is in the middle of the tape, try to avoid the size of the edge, and the adhesive tape is firmly attached to the film without obvious bubbles;
3. The membrane surface at the interface is required to be smooth and without obvious wrinkling;

So, how can modern PET film slitting machines precisely address these two major pain points through technological innovation?
