Problems solved by technology

When ordinary BOPP film is used for laser processing, the molding temperature must be higher than 100°C to emboss a clear pattern, but as the temperature rises, the precipitates on the surface of the film increase rapidly. Generally, frequent shutdowns are required to clean the molding plate within 1 to 2 hours. Roller, low production efficiency

Abstract

The invention discloses a BOPP base film with high aluminum plating fastness for low-temperature laser molding, which is composed of an outer surface layer, a middle layer and an inner surface layer, and the inner surface layer is a molding layer; the inner surface layer includes the following raw materials in mass percentage: anti-blocking masterbatch 1-10%, maleic anhydride graft-modified polypropylene 10-20%, and the balance is modified molding masterbatch; the modified molding masterbatch is composed of propylene-butadiene-ethylene terpolymer, α-olefin, The metallocene linear low density polyethylene is prepared by blending according to the mass ratio (40-90):(20-40):(20-40). The invention also discloses a preparation method of a BOPP base film with high aluminum plating fastness for low-temperature laser molding. The BOPP base film of the present invention can be used for molding at a low temperature of 80° C. and then lasered, and has the advantages of low molding temperature, low thermal shrinkage rate, high aluminum plating fastness, and excellent physical and optical properties.

Description

technical field [0001] The invention relates to the technical field of film materials, in particular to a BOPP base film with high aluminum plating fastness for low-temperature laser molding and a preparation method thereof. Background technique [0002] Laser technology is a technology that uses 3D color holographic molding method to transfer the holographic image with rainbow dynamic and three-dimensional effect to the film substrate. After the substrate is molded and aluminized, the surface of the packaging material has the effect of laser laser through lamination, hot stamping, transfer and other processes. [0003] Laser packaging is a high value-added product in the packaging industry, and has achieved rapid development in recent years. Compared with other products in the packaging industry, laser packaging materials not only have a novel and bright appearance, but also have high-tech anti-counterfeiting functions. Known as the most cutting-edge technology products in...
