I don’t know if you have noticed that most of the chicken legs, beef jerky and other products sold in supermarkets or stores are packed with quality foil aluminum bags, and most of them are vacuum packed. But why? Why not just use regular bags? Let's analyze it from four aspects.

1. Foods such as chicken legs have hard bones, which requires the materials used for packaging to have strong mechanical properties, blast resistance, puncture resistance and tear resistance. Quality foil aluminum bags just have these performance characteristics. While ensuring the food storage cycle, it also has strong anti-destructive properties, and ordinary packaging bags do not have these characteristics.

2. The aluminum foil material is non-toxic and tasteless, and meets the hygienic packaging standards for food, medicine, etc., and has the characteristics of good heat sealing performance, high flexibility and high barrier performance. It is the best choice for food packaging.

3. The cooked food products we buy have a characteristic, that is, they are ready to eat after opening the bag, and because they are all cooked, they cannot be stored for a long time, and they need to be protected from light during storage to prevent accelerated product spoilage. The aluminum foil packaging bag can isolate the air very well, and has the characteristics of anti-oxidation, waterproof, moisture-proof, etc., which can greatly improve the preservation period of food and facilitate the long-distance transportation of food.

4. Food needs to be sterilized before and after the quality foil aluminum bags are installed. The aluminum foil material has good high temperature resistance (121 ° C), low temperature resistance (-50 ° C), oil resistance, fragrance preservation and other properties.
