Easily-torn composite film composition, easily-torn composite film and preparation method of easily-torn composite film

The invention relates to the technical field of macromolecules, in particular to an easy-to-tear composite film composition, an easy-to-tear composite film and a preparation method of the easy-to-tear composite film. The easy-to-tear composite film is characterized in that the composition comprises a first-layer film material, a middle-layer film material and a third-layer film material; the first layer of film material is a base material layer film material; the middle layer membrane material is a supporting layer membrane material; the third layer of film material is a bonding layer film material; based on the total weight of the third-layer membrane material, the third-layer membrane material is prepared from 100 parts of ethylene-vinyl acetate copolymer, 3 to 13 parts of adhesive and 0.1 to 0.5 part of slipping agent. The easy-to-tear composite film prepared from the easy-to-tear composite film composition provided by the invention has excellent heat sealing performance and easy-to-tear performance when b
