What determines the thickness of the stretch film?

<p><a href="https://www.kinttape.com/" rel="noopener noreferrer" target="_blank">Stretch film</a> is made of many sizes. Stretch films of different thicknesses have different functions. The thickness of the <a href="https://www.kinttape.com/" target="_blank">stretch film</a> determines the packaging cost and performance requirements. What can determine the thickness of the stretch film? Listen to the sharing of Jintai Yongji technicians!</p><p><br></p><p>The thickness of the stretched film can be determined by market generalization and standardization, the strength support is generally determined according to the weight of the packaged product, and the thickness of the functional stretched film is generally determined by the shelf life of the product. In order to know the thickness of the stretched film more clearly, we can start from the following points:</p><p><br></p><p>1. According to the larger allowable water absorption of the packaged product or the larger allowable dehydration of the product, this method is mainly suitable for the moisture-proof packaging design of the product, and the key is to calculate the moisture permeability coefficient of the stretched film.</p><p><br></p><p>2. According to the larger allowable oxygen absorption of the packaged product, this method is mainly suitable for product barrier packaging where the product is very sensitive to oxygen. The key is to calculate the oxygen permeability coefficient of the stretched film.</p><p><br></p><p>3. It is determined according to the number of microorganisms per unit volume or unit surface area. This method is mainly suitable for anti-mold packaging where the product is very sensitive to microorganisms. The key is to determine the type of product microorganisms and the rules of reproduction and growth.</p><p><br></p><p>In addition, it can also be determined according to the larger amount of carbon dioxide or oxygen permeable allowed by the stretched film. This method is mainly aimed at the inflatable insurance packaging of the product. Products with declarative activity need oxygen insurance or maintain a bright color and high concentration. Carbon dioxide to inhibit the growth and reproduction of microorganisms, the key is to calculate the oxygen permeability coefficient and carbon dioxide permeability coefficient of the stretched film.</p>
