Using stretched film, the problem of poor ductility is often encountered. Which is also a headache for users, and poor ductility leads to poor packaging. Which greatly reduces the effect of packaging, so customers should pay attention to packaging Contact buy, and it is necessary to determine the malleability of the package.

Flat film, then how to identify high quality. Flexible stretch film? The manufacturer will be less specific about your stretched film: main, tear along the length of the stretched film and then tear it horizontally. The impact of the expansion is very strong and the tolerance is not good. If it is too thin, patience will be greatly reduced. Expansion is not good. Thus, the manufacturer of stretched film reminds you: buy stretched film, do not blindly want cheap, but it is not easy to buy stretched film.

The performance advantages of stretched film can be said to be diverse, mainly from the choice of materials, processing technology and other aspects. If the process technology is not qualified, then it can not achieve the effect of high-quality products, so it not only depends on the use of the product. But also its processing technology is also very important, but many people do not know it very well, we can simply from the simple coefficient Start with definition.
