　　Composite Vacuum Zipper Bag refers to compounding two or several thin -film -differentials with different segregated functions through certain techniques. In this way, in order to arrive in the packaging, the permanent molecules must pass several layers of membranes, which is equivalent to extending the soaking pathway, so that the isolation function can improve. This method is a composite film that summarizes the strengths of various membranes and is prepared by a composite film. Its craftsmanship is simple. However, compared with the high -isolation data of this lecture, this method is used to prepare the thickness of the thin film and simply present the problem of beingo -functional functions such as bubbles or cracking folds, and the equipment requirements are relatively messy and the capital is higher. Composite Vacuum Zipper Bag is commonly used on the packaging of solid and powder. When the heavier content is instantly impacted (for example, if it falls), it has higher requirements for the sealing strength. From the perspective of the data structure, it is only that progressive stretching intensity cannot solve the problem. The torn strength of the data seems to be able to improve the impact strength more obviously.
