Title:
BOPP DOUBLE-SIDED HEAT-SEALING LASER ANTI-COUNTERFEITING BASE FILM AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/010615
Kind Code:
A1
Abstract:
A BOPP double-sided heat-sealing laser anti-counterfeiting base film, comprising an upper-layer structure, a middle-layer structure and a lower-layer structure which are arranged in sequence. The upper-layer structure is used to provide a good heat sealing performance, good smoothness and anti-adhesion performance between films; petroleum resin and an antistatic agent are added to the middle-layer structure enabling same to have a high shrinkage rate, modulus and antistatic effect; and low-temperature heat-sealing metallocene and a propylene-ethylene-butadiene terpolymer are added to the lower-layer structure, so that mixed and modified films have a low sealing temperature and a good mold pressing effect, thereby enabling the obtained BOPP double-sided heat-sealing laser anti-counterfeiting base film to have the advantages of good heat sealing, heat resistance of patterns after mold pressing being good, low raw material costs and the like.
