Nowadays, people’s living standards have generally been improved, so people are more and more concerned about health issues. And whether the food packaging bags that everyone comes into contact with every day is safe, let you understand the requirements of food packaging bag protection.
Now the business is developing rapidly. A good food packaging bag is not only a design drawing that can be perfectly presented, but also from the aspects of materials, protection, and good packaging equipment. It is also necessary to understand the protection requirements of food packaging bag design. Hope it can help you:
The chemical composition and physical and chemical properties of different foods are different, so different foods have different protection requirements for packaging. For example, the packaging of tea should have high oxygen resistance (to prevent the oxidation of active ingredients), high moisture resistance (tea leaves become damp and moldy), high light resistance (chlorophyll will change tea sunlight), and high aroma resistance (tea aroma molecular components) It is easy to be distributed and lose the taste of tea. In addition, tea is also easy to absorb external odors. At present, a considerable part of the tea on the market is packaged in ordinary PE, PP and other transparent plastic bags, which greatly wastes the effective ingredients of the tea. , Tea quality cannot be guaranteed.
