technical field [0001] The invention relates to a plastic film, in particular to a flame-retardant polypropylene plastic film. Background technique [0002] At present, with the development of the economy, plastics have been widely used in industry and life. China's plastic film industry is in a stage of vigorous development. It is reported that the demand for China's plastic film will grow at a rate of more than 9% every year. Moreover, with the continuous emergence of various new materials, new equipment and new processes, China's plastic films will be developed in the direction of diversified, specialized and multifunctional composite films. As a general-purpose material, polypropylene is widely used due to its small specific gravity, easy processing, corrosion resistance, non-toxicity and excellent comprehensive performance. Most polypropylene films now have the problem of flammability. Contents of the invention [0003] The object of the present invention is to prov...
