一次性環（huán）保餐具廠家分享吹（chuī）膜的基（jī）本性能和技術要求

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

　　1.物理機（jī）械性能

　　1. Physical and mechanical properties

　　由於吹塑聚乙烯薄膜用於印刷或複合加工過程中，要受到機械力的作（zuò）用，因此，對聚（jù）乙烯（xī）薄（báo）膜的物理力（lì）學性能的要求應良（liáng）好，主要包括抗拉強度、斷裂伸長率、撕裂強度（dù）等指標應符合標準。

　　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.外觀

　　2. appearance

　　要求聚乙烯薄膜塑化良好，無明顯“水紋”和（hé）“雲霧”;薄膜表麵應平整光滑，無褶皺或僅有少量活褶皺。不允許有（yǒu）氣泡、穿孔或破（pò）裂;無明顯黑（hēi）點、雜質、晶點、硬塊;不允許有嚴（yán）重的掛起和線程。

　　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.規範和偏差（chà）

　　3. Specifications and deviations

　　聚乙（yǐ）烯薄膜的寬度和厚度應符合要求。薄膜（mó）的厚度（dù）應該是（shì）均勻的。水（shuǐ）平和垂直薄（báo）膜的厚（hòu）度偏差應（yīng）較小，且偏差分布（bù）應相對均勻。

　　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.
