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 high-aluminizing-fastness BOPP base film for low-temperature laser mould pressing, which consists of an outer surface layer, a middle layer and an inner surface layer, wherein the inner surface layer is a mould pressing layer and is prepared from the following raw materials in percentage by mass: 1 to 10 percent of anti-blocking master batch, 10 to 20 percent of maleic anhydride grafted modified polypropylene and the balance of modified mould pressing master batch; the modified mould pressing master batch is prepared by blending a propylene-butadiene-ethylene terpolymer, alpha-olefin and metallocene linear low-density polyethylene according to a mass ratio of (40-90) : (20-40) : (20-40). The invention also discloses a preparation method of the BOPP base film withhigh aluminizing fastness for low-temperature laser mould pressing. The BOPP base film disclosed by the invention can be used for mould pressing under a low-temperature condition of 80 DEG C, and thenlaser is carried out; the BOPP base film has the advantages of low mould pressing temperature, low thermal shrinkage rate, high aluminizing fastness, excellent physical properties, excellent opticalproperties and the like.

Description

technical field [0001] The invention relates to the technical field of film materials, in particular to a BOPP base film with high aluminizing 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 to transfer holographic images with rainbow dynamics and three-dimensional effects to film substrates. After the substrate is molded and aluminized, the surface of the packaging material has a laser effect through lamination, hot stamping, transfer and other processes. [0003] Laser packaging is a high value-added product in the packaging industry. It has achieved rapid development in recent years. Compared with other products in the packaging industry, laser packaging materials not only have novel and bright appearance effects, but also have high-tech anti-counterfeiting functions. Known as the most cutting-edge technology product in the world's packaging ...
