The tearable granule 7 is made of polynorbornec acid, and its diameter is 0.3-0.5 μm. By utilizing the characteristic that the polynorbornec acid is incompatible with LLDPE, the polynorbornec acid is uniformly dispersed in LLDPE by adopting a high-speed blending process to form an island-sea structure, so that when the film is torn, a tearing interface extends along the phase-splitting interface of LLDPE and polynorbornene, and the film has low tearing strength and certain linearity. The LLDPE material is selected, so that the tensile property, the penetration resistance and the impact resistance of the LLDPE material are good, but the LLDPE material is only used for the outer layer due to the cost consideration, so that a good protection effect is achieved.
