When choosing frozen food packaging bags, the main components of frozen food should be studied first, especially the sensitive factors that affect nutritional components such as fat, protein, and vitamins, including light, oxygen, temperature, microorganisms, physical and mechanical factors. Then, based on the protection requirements of the content and transportation environment, determine the type of packaging materials and the operation mode of packaging technology to achieve protection functions and appropriately extend the shelf life.
1、 Health: From a safety perspective, packaging materials that come into direct contact with food (such as plastic bags) must be food grade. The packaging and transportation process of frozen food is usually difficult to ensure that the entire process is carried out in a continuous low temperature environment, especially during transportation and handling, which may cause the temperature of frozen food to significantly increase over a certain period of time. If the raw materials are not qualified, it is easy to produce bacteria. Compared to packaging made from food grade materials, packaging made from recycled or industrial grade materials does not have much difference in appearance, but it contains substances such as plasticizers that exceed the standard. Once used, it can cause great harm to human health.
2、 Cold resistance: Frozen foods are usually stored and circulated at temperatures of -18 ℃ or lower, especially some frozen foods with pallets. In the production process, food and pallets are usually quickly cooled at -30 ℃ until the central temperature of the product is below -18 ℃, and then packaged. When the temperature drops suddenly, the mechanical strength of the packaging material also decreases, leading to the fragility of the packaging material.
In addition, frozen food inevitably suffers from impacts, shocks, pressures, and other environmental hazards during transfer and transportation. In addition, frozen foods such as rice dumpling and dumplings are difficult to eat at low temperatures. Easy to cause cracking and cracking of packaging bags, which requires packaging materials to have good low-temperature performance.
