(1)出产工艺流程。硬质PVC包装膜出产工艺流程如下。种种质料→捏合→冷拌跟→挤出吹塑→PVC玻璃纸基膜→抗静电、热封涂覆处置→分切→测验→包装→制品本工艺流程采取粉料直接挤出吹塑成型，制成玻璃纸基膜后，亦可直接作为制品，而不经抗静电、热封涂覆处置。

(2)出产工艺。硬质PVC通明包装膜个别采取挤出上吹成型工艺，重要工艺前提先容如下。①配料捏合。将PVC树脂及其余助剂按配朴直确称量后，放入高速捏合机，捏适时光5~8min，温度102℃左右，物料捏合好后放入冷却器停止冷却，待物料温度落到40-50℃以下即可放

1 production process. RIGID PVC packaging film production process is as follows. Seed Material → kneading → cold mixing → extrusion blow molding → PVC cellophane base film → antistatic, heat sealing coating → cutting → testing → packaging → product direct extrusion blow molding, made of Cellophane base film, can also be directly used as products, without anti-static, heat sealing coating disposal. 2 production process. RIGID PVC transparent packaging film individual to adopt extrusion blow molding process, the important process premise as follows. 1 Ingredient kneading. The PVC resin and other auxiliaries are weighed accurately according to the match plain, put them into high-speed kneading machine, kneading time is 5 ~ 8 minutes, the temperature is about 102 °C, after kneading the materials, put them into the cooler to stop cooling, wait for the temperature of the materials to fall below 40-50 °C
