Manufacturing method of PET film puncher for multi-layer battery

A PET film puncher for multi-layer batteries

technical field

1. The present utility model relates to the technical field of battery packaging, in particular to a pet film puncher for multi-layer batteries.

Background technique:

2. pet plastics are polyethylene terephthalate plastics, mainly including polyethylene terephthalate pet and polybutylene terephthalate pbt. Packaging, due to the relationship between the volume and position of the connecting line of the battery, it is necessary to cut a placement slot on the pet film to facilitate the placement of the connecting line, and the common method of cutting the pet film is to manually cut it with scissors. This method Not only is the efficiency low, the manpower waste is serious, and the quality of the treated pet film cannot be guaranteed, and it also has a certain impact on the personal safety of workers.
