From the perspectives of packaging cost and performance requirements, the selection of thickness for each layer of composite packaging bags should be carefully balanced. Generally speaking, the heat sealing layer can be determined through market generalization and standardization, the strength support layer is generally determined based on the weight of the packaged product, and the thickness of functional materials is generally determined by the shelf life of the product.
1. Based on the maximum allowable water absorption or maximum allowable dehydration of the packaged product, this method is mainly suitable for moisture-proof packaging design of the product, and the key is to calculate the oxygen permeability coefficient of the composite packaging bag.
2. Based on the maximum allowable oxygen absorption of the packaged product, this method is mainly suitable for 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. Based on the maximum allowable number of microorganisms per unit volume or surface area, this method is mainly suitable for anti mold packaging products that are highly sensitive to microorganisms. The key is to confirm the types of microorganisms in the product and their reproductive and growth patterns.
4. Based on the maximum allowable carbon dioxide or oxygen permeability of the packaging container, this method is mainly aimed at inflatable safety packaging of products. Products with declared activity require oxygen safety or maintain bright colors, as well as high concentrations of carbon dioxide to inhibit microbial growth and reproduction. The key is to calculate the oxygen permeability coefficient and carbon dioxide permeability coefficient of composite packaging bags.
When packaging products, sometimes it is necessary to achieve both moisture-proof packaging and oxygen resistant or mold resistant packaging. Therefore, generally, the thickness of each layer of composite packaging bag is determined based on the main packaging purpose and shelf life of the product packaging, and then the theoretical shelf life of the designed packaging is estimated based on the thickness of the material and another packaging purpose to verify the rationality of the designed packaging.
