Problems solved by technology

[0002] The packaging film of cigarette cartons will cause friction during the transportation of cigarettes, between cartons and cartons, and between cartons and packing boxes, resulting in fine scratches on the surface of the film. The large whitening phenomenon seriously affects the transparency of cigarette packaging, weakens the display of cigarettes, affects the vision, and lowers the grade of cigarette products. Therefore, the cigarette packaging market puts forward the requirement of wear-resistant packaging film
The currently used cigarette packaging film mainly uses homopolypropylene as the core layer, polypropylene copolymer as the surface layer as the heat-sealing layer, and polypropylene copolymer as the surface material in contact with the outside world. Its hardness is small and it is easy to be scratched. And the melting point is also low. After friction and heating, it will soften and become sticky, and the scratching will be more serious.
The patent application of CN201010269824 discloses a BOPP film for nano wear-resistant box cigarette packaging, which has added nano-scale silicon dioxide particles, so that the prepared film has good wear resistance, but the nano-scale silicon dioxide particles in the film During the production process, there will be problems such as feeding difficulties and difficulty in dispersing, resulting in low film yield; therefore, other better methods are needed to improve the wear resistance of the film

Abstract

The invention discloses a wear-resisting cigarette barrel packaging film and a fabrication method thereof. The film solves the problem that the wear resistance of the existing cigarette barrel packaging film is poor, and the cigarette barrel packaging film is prepared by double coating PVDC (polyvinyl dichloride) paint on a two-way stretch flat film by employing the characteristics of wear resistance, good hardness and low possibility of scratches of the PVDC material. The wear resistance of the wear-resisting cigarette barrel packaging film is good; the films move and rub back and forth at a speed of 12m / min under a pressure of 0.25kg; the haze of the worn commonly-used cigarette packaging film increases by about 30%; but the haze value of the worn cigarette barrel packaging film only increases by 9%.
