Preparation method of puncture-resistant tear-resistant high-transparency PE/POE/CBC blended cast film composition

The invention discloses a preparation method of a puncture-resistant tear-resistant high-transparency PE/POE/CBC blended cast film composition, and relates to a film material, and the composition comprises the following components by weight: 60-80% of linear low density polyethylene, 10-20% of a polyolefin elastomer, 10-20% of a cyclic block copolymer, and 0.1-0.8% of a slipping agent. The puncture-resistant tear-resistant high-transparency PE/POE/CBC blended cast film composition solves the problems of poor transparency, weak puncture resistance, insufficient tensile strength and insufficient elongation at break of a PE plastic film, and a finished product prepared by the preparation method and production process of the puncture-resistant tear-resistant high-transparency PE/POE/CBC blended cast film composition has good mechanical properties and optical properties, can obviously play a role in puncture resistance, improves the transparency, and is suitable for large-scale production. The application range of
