It is used in a wide range of fields from industrial use such as fixing parts and electric and electronic materials to general household use and medical use materials. Such an adhesive tape is basically obtained by applying an adhesive to a film-like base material such as PVC (polyvinyl chloride), PP (polypropylene), or PET (polyethylene terephthalate). Is very important in determining the quality of the adhesive tape or sheet. That is, if the anchoring property is weak, peeling occurs between the adhesive and the base material when the tape is rewound or when the tape is peeled off, which causes various troubles. Therefore, various surface treatments and primer treatments have been performed on the base material for the purpose of improving anchoring properties.
