[0002] The sealing of the vehicle body involves the anti-corrosion, shock absorption and noise reduction performance of the vehicle body. The sealing of the vehicle body is one of the important evaluation indicators for determining the quality of the entire vehicle, and it also directly affects the driving experience of the drivers and passengers. During the production process of the vehicle body, it is necessary to open a variety of openings on the surface of the vehicle body, including process holes, flow holes, structural holes, etc. The above openings all need to be sealed with plugging patches to improve the sealing of the vehicle body.

[0003] The plugging patch is made of a thin sheet of PET or PVC coated with acrylic glue. During the car body manufacturing process, the operator can peel the plugging patch from the backing paper and stick it to the outside of various openings on the surface of the car body to seal the car body; when the operator peels off the plugging patch, it is easy to accidentally touch the acrylic glue surface, causing external contamination to the glue surface, resulting in a decrease in adhesion, making the plugging patch not firmly bonded, and easily causing warping, which in turn affects the sealing performance of the car body.
