Development of wrinkle resistant and antifouling BOPP cigarette packaging film

when BOPP film is used in cigarette packaging, due to the effect of residual solvents in cigarette paper ink, BOPP film will wrinkle due to the absorption of these residual solvents, and at the same time, it will lead to a significant increase in the haze of the film, so that cigarette packaging loses its fixed segment, which can realize fixation and control activities, and enhance the smooth and smooth packaging appearance. Therefore, for many years, BOPP film manufacturing industry and cigarette film users have been committed to developing and seeking BOPP cigarette film that can resist the residual solvent of cigarette peel. At present, in order to solve this problem, PVDC coating film is mainly used. Although PVDC coating film has the ability to resist residual solvents, the surface weight of the film is relatively small, and because the film contains toxic element C1, from the perspective of environmental protection, PVDC coating film is not the best choice. Therefore, it is necessary to develop a BOPP packaging film with better performance price ratio, environmental friendliness, wrinkle resistance and antifouling for smoke. This project has successfully developed a new type of high-performance wrinkle resistant and antifouling BOPP film for smoke by using new materials, new technologies and new processes. This film has the ability to resist the influence of residual solvent in cigarette paper packaging, overcomes the defects of wrinkle, stain and haze of traditional BOPP cigarette film caused by residual solvent, and is pollution-free. It can replace PVDC coating film. The anti wrinkle and antifouling film developed in this project has high gloss, low haze and high film rigidity, and is suitable for industrial systems characterized by other new materials of various types of cigarette packaging machines. At present, Sichuan Zhongda new materials Co., Ltd. has been able to produce a series of anti wrinkle and anti fouling BOPP films for smoke

(1) economic benefit estimation at present, the price of PVDC coated BOPP film commonly used in domestic cigarette packaging is 32000 yuan/ton, while the price of wrinkle resistant and antifouling BOPP film developed in this project is about 30000 yuan/ton. Based on 4000 ~ 5000 tons of BOPP film coated on cigarettes every year, the cost can be saved about 8-10 million yuan, and the economic benefit is very considerable. (2) Promotion and application conditions and prospects the batch trial production of wrinkle resistant and antifouling BOPP cigarette film provides complete technical conditions for the promotion and application of BOPP film in the cigarette packaging industry from the perspective of melt activity distance. Because the BOPP film developed by the project has the ability to resist solvent penetration, it is also expected to be widely used in the packaging fields of food, medicine and so on

achievement introduction: 1bopp film is widely used in cigarette packaging. China is a large country in the production and application of cigarette film, and about 60000 tons of BOPP cigarette film are required every year. When BOPP film is used in cigarette packaging, due to the effect of residual solvent in cigarette paper printing ink, BOPP film will wrinkle due to the absorption of these residual solvent software, which can set limit alarm and shutdown protection and other functional agents. At the same time, it will lead to a significant increase in the haze of the film and make the cigarette packaging lose its flat and smooth packaging appearance. Therefore, for many years, BOPP film manufacturing industry and cigarette film users have been committed to developing and seeking BOPP cigarette film that can resist the residual solvent of cigarette peel. At present, in order to solve this problem, PVDC is mainly used to coat BOPP film. Although PVDC coated BOPP film has the ability to resist residual solvents, the surface weight of the film is relatively small, and because the film contains toxic element C1, from the perspective of environmental protection, PVDC coated film is not the best choice

therefore, it is necessary to develop a BOPP packaging film with better performance price ratio, environmental friendliness, wrinkle resistance and antifouling smoke. This project is entrusted by Sichuan University by Sichuan Zhongda new materials Co., Ltd. and jointly completed by both parties. The project successfully developed anti wrinkle and anti fouling BOPP film for smoke. This film has the ability to resist the influence of residual solvent in cigarette paper packaging, overcomes the defects of wrinkle, stain and haze increase caused by residual solvent in traditional BOPP cigarette film, and is pollution-free, which can replace PVDC coating film. The anti wrinkle and antifouling film developed in this project has high gloss, low haze and high film rigidity, and is suitable for various types of cigarette packaging machines
