A special silicone-type wear-resistant strip-wrapped BOPP film and its preparation method

Abstract

The invention provides a special silicone type wear-resistant BOPP film for wrapping a cigarette carton and a preparation method of the special silicone type wear-resistant BOPP film. The film is prepared by an upper surface layer, a core layer and a lower surface layer through direct coextrusion-lamination, and special silicone type slipping agent master batch and modified anti-sticking agent master batch are added into the upper surface layer. By adding the special silicone type slipping agent master batch and the silicone oil processed silicon dioxide anti-sticking agent into the upper surface layer, the normal-temperature and high-temperature friction coefficient of the film are increased in a balanced manner, and whitening and fogging are avoided.

Description

technical field [0001] The invention belongs to the field of film materials, and in particular relates to a special silicone-type wear-resistant strip-wrapped BOPP film and a preparation method thereof. Background technique [0002] The BOPP cigarette film with poor wear resistance often has defects such as whitening and fogging of the box packaging after packaging and transportation. Considering the pickiness and habits of domestic consumers, it will be at a disadvantage in sales. In order to cater to the psychology of consumers, major tobacco factories pay more attention to the packaging effect, so the wear-resistant stick film has a broad market prospect. [0003] After years of continuous research and development, according to different required performances, three mature products have been formed for customers to use in batches. Although the grinding of the existing wear-resistant products in the process of processing and transportation cannot be completely eliminated,...

AI Technical Summary

Problems solved by technology

Although the grinding of the existing wear-resistant products in the process of processing and transportation cannot be completely eliminated, especially the grinding of the transportation is more obvious, the downstream tobacco factories can only accept it by default

Although packing the cartons of cigarettes into boxes more compactly will reduce the shaking during transportation, but being too compact will also increase the difficulty of packing into boxes; if the gap between the cartons is controlled at an appropriate value during packing, the During the process, due to the shaking of the vehicle, the barrels will rub against each other. When they reach the hands of consumers, they will find that the barrels are more worn, which will have a negative impact on the desire to buy.
