Composite bags decided the product performance, each layer thickness difference by one false step will make a great difference!

Considering from two aspects of the packaging cost and performance requirements, composite bags the thickness of each layer selection should be weighed. In general, the heat sealing layer can be determine by market generalization and standardization, the intensity of support layer generally according to determine the weight of packaging products, while the thickness of the functional materials generally decided by the shelf-life of the product. The professional manufacturer of flexible packaging packaging is to analyze the composite bags is how to determine the thickness of each layer. 1, according to the maximum allowable water quantity or packaged products of maximum allowable water to determine, this method is mainly used moistureproof packaging design of products, the key is to calculate the air coefficient of composite bags. 2, according to the maximum allowable oxygen uptake of the packaging products, the method is mainly used for the product is sensitive to oxygen barrier property of product packaging, the key is to calculate the air coefficient of composite bags. 3, according to the unit or the unit surface area is the largest volume allows to determine the number of microorganisms, the method is mainly used for product is sensitive to microbial anti-mold packaging, the key is to confirm the product microbial species and reproductive growth of rules, etc. 4, according to the maximum allowable packaging container through carbon dioxide and oxygen permeability, this method is mainly in view of the inflatable insurance packaging products, a product with the statement activity both need oxygen insurance or keep bright-coloured colour and lustre, high concentrations of carbon dioxide and needed to inhibit the growth of microbial breeding, the key is to calculate the air coefficient of composite bags and coefficient of carbon dioxide. Product packaging, sometimes both to achieve the purpose of moisture-proof packaging, and to achieve the purpose of oxygen packing or mildew resistance. Therefore, generally start with packaging for some main purpose and the product shelf-life composite bags the thickness of each layer is determined, according to the thickness of the material and another packing purpose to estimate the designed theory shelf life, to verify the rationality of the design of packaging. The packing bag of reasonable design, coupled with exquisite printing, will add splendor to your product!
