Standard Requirements For Stretch Film Raw Materials

If there are no standard requirements for the production, use, packaging and other aspects of a product, there will be many problems, resulting in the use of these products is not good. Stretch film is the same, the standard requirements of its raw materials are done, then the quality of the product will be guaranteed. But the problem is that many manufacturers now think that the product is a small business, its quality, performance and so on does not matter, but also think that what kind of material of the product can be used, so now many people will buy some inferior products, a pull off. So, the raw material of the product is very important, so what are the standards for the raw material?

1, no black impurities, mold head to wash clean, no burnt plastic fall into, if the naked eye can be found must be removed immediately.

2, the paper tube must be aligned, not one side long and one side short. The margin on each side is about 1 centimeter.

3, the edge material is broken to cut neatly, if the uneven cutting can not be shipped as finished products. Including when doing goods, both ends must be rolled neatly, not more on one side and less on the other.

4, as far as possible to reduce the two ends of the surface folds and the middle of the white pressed lines (this will seriously affect the aesthetic degree).
