Embodiment 1
[0016] Embodiment 1: (by mass)
[0017] The formula of PE heavy packaging film material composition is:
[0018] Linear Low Density Polyethylene: 70%,
[0019] (Select the product whose comonomer is octene)
[0020] LDPE: 10%,
[0021] (Select LDPE165 from Exxon, USA)
[0022] Metallocene linear low density polyethylene: 16%,
[0023] (Choose 1018CA from Exxon, USA)
[0024] Anti-blocking agent, slip agent, antistatic agent, antioxidant, processing and heat stabilizer: According to a certain proportion, the total accounts for 4%.
[0025] After the three-layer co-extrusion blown film production line is extruded according to the production process, the performance of the product is sampled and analyzed. The mechanical properties of the obtained product all meet the standards, and compared with other heavy packaging products, the puncture resistance and film strength are significantly improved. . The specific data are as follows:
[0026]
Embodiment 2

[0031] (Select LDPE165M from Beijing Yanhua Company),
[0032] Metallocene linear low density polyethylene: 10%
[0033] (Choose 1018CA from Exxon, USA)
[0034] Anti-blocking agent, slip agent, antistatic agent, antioxidant, processing and heat stabilizer: According to a certain proportion, the total accounts for 4%.
Embodiment 3
[0035] Embodiment 3 (by mass)
[0036] Linear Low Density Polyethylene: 60%,
[0037] (select the comonomer to be the product of octene),
