      (1)出產工藝流程。硬質PVC包裝膜出產工藝流程如下。種種質料→捏合→冷拌跟→擠出吹塑→PVC玻璃紙基膜→抗靜電、熱封涂覆處置→分切→測驗→包裝→制品本工藝流程采取粉料直接擠出吹塑成型,制成玻璃紙基膜后,亦可直接作為制品,而不經抗靜電、熱封涂覆處置。
      (2)出產工藝。硬質PVC通明包裝膜個別采取擠出上吹成型工藝,重要工藝前提先容如下。①配料捏合。將PVC樹脂及其余助劑按配樸直確稱量后,放入高速捏合機,捏適時光5~8min,溫度102℃左右,物料捏合好后放入冷卻器停止冷卻,待物料溫度落到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
