pvc拉鏈袋發生褶皺需要注意什么？
pvc拉鏈袋中常用的問題有兩種：一類是拉鏈兩邊的部分層次或表層褶皺;另一類是拉鏈與袋體封合處的表層褶皺。
There are two common problems in pvc zipper bags: one is the partial layers or surface wrinkles on both sides of the zipper; The other is the surface fold at the seal between the zipper and the bag body.
pvc拉鏈袋兩邊出現褶皺有時候與拉鏈的挑選有緊密的關聯，在購買拉鏈時一定要留意其熔點與縮水率要小于或相當于復合膜熱封層的熔點與縮水率，以防因熔點與縮水率比較嚴重不配對的狀況下出現的褶皺狀況。
Folds on both sides of PVC zipper bags are sometimes closely related to the selection of zippers. When purchasing zippers, it is necessary to pay attention to the fact that their melting point and shrinkage rate are less than or equal to the melting point and shrinkage rate of the composite film thermal sealing layer, in order to prevent wrinkles caused by serious mismatch between the melting point and shrinkage rate.
