Embodiment 1
[0027] Embodiment 1. An antistatic degradable film material is made of the following raw materials in parts by weight: 60 parts of LDPE, 18 parts of LLDPE, 10 parts of a compound blended with thermoplastic starch and aliphatic polyester, antistatic masterbatch 2 parts of granules, wherein the mixing weight ratio between thermoplastic starch and aliphatic polyester is 1:1.
[0028] Preparation:
[0029] (1), weigh LDPE, LLDPE, starch-based degradable plastic raw materials and antistatic masterbatch, and mix them uniformly to form a mixture;
[0030] (2) Put the mixture into the film blowing machine for plasticizing and extruding; the temperature of the feeding section of the blowing film machine is set at 130°C to 140°C, and the temperature of the plasticizing section is set at 160°C to 175°C. Die head temperature 160°C;
[0031] (3), the plasticized extruded material is blown and drawn to make a film, and then the air ring is cooled; wherein the blow-up ratio is 2.5, and the...
