The thickness of each layer of the composite packaging bag determines the performance of the product, and the difference is a thousand miles away!

Considering the two aspects of packaging cost and performance requirements, the thickness selection of each layer of the composite packaging bag should be carefully weighed. Generally speaking, the heat sealing layer can be determined by market generalization and standardization, the strength support layer is generally determined according to the weight of the packaged product, and the thickness of the functional material is generally determined by the shelf life of the product. ​The following professional flexible packaging manufacturers will analyze how the thickness of each layer of the composite packaging bag is determined. 1. Determined according to the maximum allowable water absorption of the packaged product or the maximum allowable dehydration of the product. This method is mainly adapted to the moisture-proof packaging design of the product. The key is to calculate the oxygen permeability coefficient of the composite packaging bag. 2. Determined according to the maximum allowable oxygen absorption of the packaged product. This method is mainly suitable for the barrier packaging of products that are very sensitive to oxygen. The key is to calculate the oxygen permeability coefficient of the composite packaging bag. 3. Determined according to the maximum allowable number of microorganisms per unit volume or unit surface area. This method is mainly suitable for mildew-proof packaging where the product is very sensitive to microorganisms. The key is to confirm the type of product microorganisms and the law of their reproduction and growth. 4. Determined according to the maximum carbon dioxide permeability or oxygen permeability allowed by the packaging container. This method is mainly aimed at the inflatable insurance packaging of the product. Products with declared activity require oxygen insurance or maintain a bright color, and high concentrations of carbon dioxide to suppress The key to the growth and reproduction of microorganisms is to calculate the oxygen permeability coefficient and carbon dioxide permeability coefficient of the composite packaging bag. When packaging products, sometimes it is necessary to achieve both the purpose of moisture-proof packaging, and the purpose of oxygen-resistant packaging or mildew-proof packaging. Therefore, the thickness of each layer of the material of the composite packaging bag is generally determined based on a certain main packaging purpose of the product packaging and the shelf life of the product, and then the theoretical shelf life of the designed packaging is estimated according to the thickness of the material and another packaging purpose to verify the design packaging. rationality. Well-designed packaging bags, coupled with sophisticated printing, will definitely add luster to your products!
