新塑料薄膜皱纹的修整新薄膜由于生产工艺上的原因卷简中间与两头边缘长度不同,两边缘长,自然形成波浪式皱纹,我们叫它“荷叶边”,不经过处理直接密封粮面,合缝粘接不牢不平不直,波浪皱纹突出。要达到密封粮面平如镜,直如尺,无皱无缝,关键是处理薄膜的“荷叶边”,我们把这种处理叫“热处理”。原来是把薄膜平铺在桌面上,再铺一层纸,用已加热的电熨斗纵横来回压熨3—4次,然后对齐边缘平整一致地把受热均匀的薄膜卷在木板上,薄膜受热软化冷却收缩达到边缘与中间长度一致,平整一致。1985年以来我们改
New plastic film wrinkle trim new film due to the production process reasons Volume Jane and the two ends of the edge of different lengths, the two edges long, naturally forming wavy wrinkles, we call it “lotus leaf edge”, without treatment directly seal the grain surface, Stitching bonding uneven uneven, prominent waves wrinkles. To achieve the seal grain noodles flat like a mirror, straight as ruler, wrinkle-free seamless, the key is to deal with the film “Ruffle,” We call this treatment “heat treatment.” The original film is tiled on the desktop, and then shop a layer of paper, with a heated iron ironing back and forth longitudinally back and forth 3-4 times, and then align the edge of a uniform and uniform heating of the film roll on the board, the film softened by heat Cooling contraction to the edge and the middle length of the same, uniform. We have changed since 1985
