Example Embodiment
[0047] Example 1
[0048] After mixing 0.09 parts of TB and 0.03 parts of DBPH with 0.3 parts of acetone solvent, then add 5 parts of LLDPE (101AA) powder resin, and mix it in a 10-liter high-speed mixer for 3 minutes to make a premixed masterbatch. Add 95 parts of LLDPE (101AA) powder resin, 0.05 part of antioxidant 1010, and 0.15 part of calcium stearate to the extruder through the feeding port, and react for 2 minutes under the condition that the temperature of the barrel is 155 to 200 ℃, and then 0.015 part of BPO and 0.04 part of acetone solvent are prepared into a solution, which is added dropwise into the plasticizing section of the extruder, and the temperature of the barrel is 200-230 ° C, after the extrusion reaction for 17 seconds, cooling, and pelletizing to prepare the composition . The composition is blown on a Φ120 three-layer composite film blowing unit to blow an ultra-wide shed film (width 14m, thickness 80μm), and its composition properties, film blowing pr...
