Degradable random copolymerization BOPP composition and application thereof

Abstract

The invention discloses a degradable random copolymerization BOPP composition and application thereof. The random copolymerized BOPP composition is prepared from the following components: microcrystalline cellulose and propylene / ethylene-1 random copolymerized BOPP, a degrading agent, an anti-blocking agent, a slip agent and an antistatic agent. The main components of the degradable composition ofthe invention are microcrystalline cellulose and propylene / ethylene-1 random copolymerized BOPP, and a uniform system is formed by uniformly mixing the degradable natural microcrystalline cellulose with additives such as a degrading agent and the like, and the excellent biological performance of the degradable natural microcrystalline cellulose and the physical performance of high transparency, impedance and high tensile strength of BOPP materials are combined, so that the prepared composite film can reach a degradation rate of 60% in 35-44 days, and impedance properties such as tensile property, haze, light transmittance, air permeability and moisture permeability can completely meet the performance requirements of cigarette films, and can be widely applied to the cigarette packaging field.

Description

technical field [0001] The invention relates to the technical field of cigarette packaging, in particular to a degradable and degradable random copolymerized BOPP composition and its application. Background technique [0002] Cigarettes, as a special mass consumer product, occupy an extremely important position in social life. Most of the outer packaging materials of cigarettes use plastic films. Discarded cigarette packaging materials have become an important part of urban garbage. Under the exacerbated situation, many countries have begun research and development of degradable cigarette packaging materials. At present, the film used for cigarettes is mainly polypropylene film. Polypropylene film has the advantages of high strength, light weight, good gas barrier property and suitable printing performance. However, BOPP cigarette film products still have high rigidity, are difficult to degrade and recycle, and are not renewable. The problem. The difficulty of developing d...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defects and deficiencies of the existing cigarette film with high rigidity and poor degradability, and provide a degradable random copolymerized BOPP composition. The degradable composition of the present invention adopts renewable and degradable natural Microcrystalline cellulose and propylene-butene random copolymer are prepared as raw materials, which reduce the structural regularity of BOPP cigarette film, improve the balance of rigidity and transparency of cigarette film, and further take into account the regeneration of materials
