Abstract

The invention relates to a BOPP (Biaxially-oriented Polypropylene) thin film for a soft-pack stiff-casement cigarette with wrinkle resistance and wear resistance and a preparation method of the BOPP thin film. The BOPP thin film is characterized by being prepared by a direct coextrusion laminating mode of a structure comprising an upper surface layer, a core layer and a lower surface layer, wherein a main component of the upper surface layer is a polypropylene copolymer; a main component of the core layer is a polypropylene homopolymer and a main component of the lower surface layer is a polypropylene copolymer. Counted by 100 parts by weight, the upper surface layer is prepared from the following material components in parts by weight: 79 to 91 parts of copolymer polypropylene, 6 to 20 parts of slipping agent masterbatch and 3 to 9 parts of anti-sticking agent masterbatch; the core layer is prepared from the following material components: 79 to 91 parts of homopolymer polypropylene, 10 to 20 parts of stiffening agent masterbatch and 2 to 4 parts of electrostatic agent masterbatch; the lower surface layer is prepared from the following material component in parts by weight: 100 parts of copolymer polypropylene. The BOPP thin film disclosed by the invention has the characteristics and the beneficial effects that special requirements of high-grade cigarettes on stiffness, shrinkage rate, transparency and the like of the BOPP thin film are met.

Description

technical field [0001] The invention relates to a BOPP film, in particular to a BOPP film for soft-packed and hard-packed anti-wrinkle and wear-resistant cigarettes and a preparation method thereof. It belongs to the technical field of BOPP film. Background technique [0002] In the manufacture of BOPP cigarette film, after nearly 20 years of research and development, the physical properties such as slippage and transparency on the machine have far surpassed foreign counterparts, but the wear resistance has always been little different from foreign countries. Cigarette films with poor abrasion resistance often have defects such as whitening and fogging after packaging. Considering the pickiness and habits of domestic consumers, they will be at a disadvantage in sales. Therefore, how to improve the wear resistance of BOPP cigarette film and how to improve the sales appearance has become a common problem that has plagued the BOPP industry for many years. [0003] According t...
