Retort Aluminum Foil Bag is a specially designed and manufactured packaging material, it can maintain stability in high temperature environment, cooking food, thus ensuring food safety and hygiene. This kind of bag has a wide range of applications in the field of food packaging, especially for foods requiring high-temperature sterilization.
1. The aluminum foil bag has good sealing performance and strong barrier property. Aluminum foil has fewer pinholes. However, if it has a pinhole itself, its barrier will be greatly reduced, the gas and light will quickly penetrate directly, and the contents will soon metamorphose.
2. Aluminum foil material texture is soft, easy to crack, to have better tolerance, the purchase of aluminum foil should be retained in the dry state, and should not be placed for too long, should be used as soon as possible to avoid aluminum foil moisture absorption oxidation and disintegration.
3. Aluminum foil bag has metallic luster, good light resistance, high reflection ability to heat and light, metallic luster and reflection ability can improve the brightness of printing color; Good isolation, strong protection, impervious to gas and water vapor, to prevent moisture absorption and gasification of the contents, not easy to be damaged by bacteria and insects.
4. Good shape stability, not affected by humidity changes. Easy to process, aluminum foil bags can be printed, color difference, embossing, surface coating, gluing and painting.
5. Aluminum foil bag has good waterproof, moisture-proof, anti-static, anti-electromagnetic interference and electrostatic shielding functions, high temperature cooking resistance, high mechanical strength, good heat sealing.
