Tear-resistant blown film and preparation process thereof

[0052] like Figure 4 to Figure 7 As shown, a preparation process of a tear-resistant blown film is used to prepare the tear-resistant film in Example 1, and the preparation steps include:

[0053] S1 material preparation, configure the master batch raw materials of inner layer 2 and outer layer 3 respectively according to the proportioning, wherein the master batch raw materials of outer layer 3 include:

[0054] HDPE 80%;

[0055] Antioxidant 1%;

[0056] UV Absorber 1%

[0057] Toughening agent 5%;

[0058] The masterbatch raw materials for inner layer 2 include:

[0059] Low density polyethylene 65%;

[0060] Linear low density polyethylene 25%;

[0061] Couplant 5%;

[0062] staple fiber mixture 5%;

[0063] S2 mix materials, put the master batch materials of outer layer 3 and inner layer 2 into two screw extruders respectively for melt extrusion to obtain blow molding materials in molten state, and set the melting temperature of the two screw extruders 105-115℃ and
