Problems solved by technology

[0002] The existing film-pressing mother film used for film extrusion laser effect is mainly PET transfer film or OPP composite film, but today's PET transfer film and OPP film have shortcomings: for PET transfer film used The problem of laser coating peeling off is easy to occur during use. The more times of use, the greater the probability of laser coating peeling off. The maximum service life is only 5-10 times, resulting in unstable mass production quality, short life, and limited use. ;For the OPP composite film used as the base film, due to the low temperature resistance of the material itself, it is prone to problems such as loss of laser effect, deformation, elastic side winding, dead wrinkles, and severe wide-width shrinkage, which reduces the pressure of mold transfer printing. quality, and the maximum service life is only 3 to 5 times; moreover, the OPP composite film has certain limitations in use, it can only be used for OPP substrates, while PET substrates cannot be used
