High temperature resistant cooking aluminum foil composite film, often referred to as "high-temperature cooking bag" or "soft can packaging", is a top-notch composite material designed specifically for harsh sterilization conditions. It combines various excellent properties and is an indispensable packaging solution for the modern food industry, especially in the fields of ready to eat dishes, meat products, sauces, and more. 

Its core performance advantages are mainly reflected in the following aspects: 

1. Excellent barrier performance: The aluminum foil layer in the composite film is its "soul", providing almost absolute barrier. It can block 100% of light (especially ultraviolet rays), oxygen, and water vapor, effectively preventing the contents from changing color, flavor, deterioration, and nutrient loss caused by light oxidation, moisture absorption, or dehydration, ensuring that the color, aroma, taste, and quality of food are highly stable during long-term storage. 

2. Excellent temperature resistance and strength: This material is designed specifically for high-temperature and high-pressure sterilization processes. At cooking temperatures ranging from 121 ℃ to 135 ℃ or even higher, it can maintain structural integrity and stability for a long time without delamination, deformation, or cracking. Meanwhile, the composite structure endows it with excellent puncture resistance and impact resistance, capable of withstanding external forces during production, transportation, and storage processes. 

3. Reliable sealing and safety: Using high-performance heat sealing layer, it can form a firm, tight and stable seal after high-temperature treatment, eliminating the risk of leakage and secondary pollution. Qualified materials themselves comply with food contact safety standards and will not release harmful substances during high-temperature cooking, ensuring food safety. 

4. Efficient processing adaptability: Good heat sealing performance makes it suitable for high-speed automatic filling and sealing equipment. More importantly, it enables packaged foods to be stored at room temperature for a long time (usually up to 1-2 years) without relying on cold chains, greatly reducing logistics and warehousing costs, and facilitating storage, transportation, and sales. 

In summary, high-temperature resistant cooking aluminum foil composite film provides comprehensive protection for food from processing to consumption through its high barrier, cooking resistance, and strong sealing properties. It is a key technology packaging material for achieving long-term preservation, stable quality, and safe and convenient food.
