What are the basic performance and technical requirements of film blowing? The disposable environmental protection tableware manufacturer will tell you!

　　1.物理机械性能

　　1. Physical and mechanical properties

　　由于吹塑聚乙烯薄膜用于印刷或复合加工过程中，要受到机械力的作用，因此，对聚乙烯薄膜的物理力学性能的要求应良好，主要包括抗拉强度、断裂伸长率、撕裂强度等指标应符合标准。

　　As blow molded polyethylene film is used in printing or composite processing, it is subject to mechanical force, so the physical and mechanical properties of polyethylene film should be good, including tensile strength, elongation at break, tear strength and other indicators should meet the standard.

　　2.外观

　　2. appearance

　　要求聚乙烯薄膜塑化良好，无明显“水纹”和“云雾”;薄膜表面应平整光滑，无褶皱或仅有少量活褶皱。不允许有气泡、穿孔或破裂;无明显黑点、杂质、晶点、硬块;不允许有严重的挂起和线程。

　　It is required that the polyethylene film should be well plasticized without obvious "water lines" and "clouds"; the surface of the film should be flat and smooth without folds or only a small amount of active folds. No bubble, perforation or fracture; no obvious black spot, impurity, crystal point, hard block; no serious suspension and thread.

　　3.规范和偏差

　　3. Specifications and deviations

　　聚乙烯薄膜的宽度和厚度应符合要求。薄膜的厚度应该是均匀的。水平和垂直薄膜的厚度偏差应较小，且偏差分布应相对均匀。

　　The width and thickness of polyethylene film shall meet the requirements. The thickness of the film should be uniform. The thickness deviation of horizontal and vertical films should be small, and the deviation distribution should be relatively uniform.
