High-gloss low-haze external packaging film for cigarette packet

Abstract

The invention discloses a high-gloss and low-haze cigarette package outer packaging film, which comprises a base film layer and functional layers arranged on the upper and lower sides of the base film layer. The functional layer is counted in parts by weight and its raw material formula As follows: 1,000-1,500 parts of hexahydrophthalic anhydride, 1,000-1,300 parts of vinyl silicone resin, 1,000-1,500 parts of nitrocellulose with a particle size of 5-15 μm, 800-1,200 parts of metallocene linear low-density polyethylene, vinegar 1200-1800 parts of acrylic emulsion, 35-50 parts of diisooctyl sulfonate sodium succinate, 10-20 parts of PVC resin, 50-80 parts of nano-aluminum oxide, 60-90 parts of dipentaerythritol, ethoxylated 30-60 parts of alkyl ammonium sulfate. The hexahydrophthalic anhydride in the formula of the present invention can improve the sharpness of image and gloss of the outer packaging film of high-gloss and low-haze cigarette packets, and at the same time, diisooctyl sodium succinate sulfonate can further solve the problem of foaming ;Using nano-alumina, it has the function of water-proof condensation and can eliminate the appearance defects of "water mist".

Description

technical field [0001] The invention relates to a high gloss and low haze outer packaging film for cigarette packs. Background technique [0002] The tobacco industry has used a variety of materials on the outer packaging film of cigarette packs, including cellophane, PVC coating film, PVDC coating film, BOPP cigarette film, etc. BOPP cigarette film has good optical properties, wide heat sealing range, high heat sealing strength, strong water vapor barrier ability, uniform thickness, wide shrinkage control range and good stiffness, etc. The incomparable characteristics of the material make it the preferred material for cigarette packaging. The traditional BOPP cigarette film for packaging has a three-layer structure. In the humid southern region, the humidity is high, and it cannot block the penetration of water vapor well, which shortens the shelf life of cigarettes; humid air is easy to condense on the surface of the cigarette film, showing "water mist" "-like appearance...

AI Technical Summary

Problems solved by technology

The traditional BOPP cigarette film for packaging has a three-layer structure. In the humid southern region, the humidity is high, and it cannot block the penetration of water vapor well, which shortens the shelf life of cigarettes; humid air is easy to condense on the surface of the cigarette film, showing "water mist" "-like appearance defects; in addition, the existing packaging film also has the problem of low gloss, which affects the use effect and aesthetics
