In general, the thickness of the stretch film can be determined by market versatile and standardization, and intensity support is generally determined according to the weight of the packaged product, and the thickness of the functional stretch film is generally determined by the shelf life of the product.

So what factors determine the thickness of the stretch film? Next, the PE stretch film manufacturer is briefly introduced. Inhibition of microorganism growth reproduction, the key is to calculate the oxygen coefficient of the stretch film and the permeable carbon dioxide coefficient. May be that the thickness of the strip film material is uneven, and the thickness is too large.

The above is the reason why the winding film has a wrinkle, I hope to help everyone.It may also be tension settings and improper control, and each part of the tension is not coordinated, and it does not match. Why do you have a wrinkle after the finished product . It may be because the position of the substrate of the wrapping film material is deflected, and the degree of wrinkles will increase accordingly as the cumulative of the skew. Why do you have wrinkles after the finished film finished? What is the cause of wrinkles in the winding film?

Next, the PE winding film manufacturer is simply introduced. 3, if the substrate is a film material that scotch packaging tape Manufacturer is susceptible to humidity, and a moisture absorption is happened, and wrinkles are easily generated during extrusion compound.

So, why is the film that will be favored by the user? 1. Next, the PE stretch film manufacturer simply introduces the role of the stretch film and choosing its advantages. The thinness of the stretch film is better, and has a high cost performance, the appearance presents a relatively transparent state, and many films are capable of sticking on both sides.
