Ho To Choose The Thickness Of PE Stretch Film? 


PE Stretch film is widely used in logistics industry to package various goods. 


1.Based on the number of the largest microorganisms per unit volume or unit surface area, This method is mainly suitable for products with mildew -proof packaging that is very 


sensitve to microorganisms. The key is to determine the types of product microorganisms the rules for their growth. 



2.According to the maximum water absorption of the packaged product or the maximum dehydration of the product, the method is mainly used to plan the moisture - proof packaging of the product, the key is to calculate the moisture permeability of the PE stretch film .



3.Based on the maximum carbon dioxide or oxygen permeability of the PE stretch film, this method is mainly for the inflatable and secure packaging of the product.Commodities with declared activity require oxygen to be stable or to maintain a bright color, High concentration of carbon dioxide is required to restrain the growth and reproduction of microorganisms. The key is to calculate the oxyen permiability coefficient and carbon dioxide permeability coefficient of the PE stretch film. 



The thickness of the PE stretch film is first determined by the packaging intention and the shelf life of the product, to verify the planned PE stretch film packaging resonableness.
