Embodiment 1
[0016] A masterbatch for plastic film products, its composition and corresponding weight percentage are as follows:
[0017]
[0018] The described manufacture method of the masterbatch that is used for plastic film product, comprises the following steps:
[0019] a. Weighing: Carrier powder PE8250, light stabilizer UV944, light stabilizer UV770, antioxidant 1010, zinc stearate SAK-ZS-PLB are weighed according to the proportion.
[0020] b. Stirring: Put the carrier and additives into the high mixer and stir in turn. The amount of the mixed material should not exceed 2 / 3 of the volume, the speed is 10-20Hz, and the mixing time is 15 minutes.
[0021] c. Pelletizing: put the compounded mixture into the extruder, and cut the pellets through the pelletizer after the material is discharged from the die.
[0022] d. Screening: The cut particles are passed through a vibrating sieve, and the masterbatch with uniform size is screened out for packaging.
