This series of film is mainly used for packaging of products that must be sterilized at high temperature. High temperature can withstand 121 ℃ reverse pressure kettle cooking, applications such as: beef tendon, beef jerky, beef trotters, marinated eggs, quail eggs, elbows, dried groundnuts, etc., meat products: ham, bacon, sausage, barbecue, roasted meat, roasted chicken, marinated eggs.
The 7-layer symmetrical co-extruded high-temperature film is carefully crafted using advanced multi-layer co-extrusion technology. Its unique PP/PP/TIE/PA/TIE/PP/PP structure not only ensures the balanced performance and excellent stability of the material, but also demonstrates extraordinary competitiveness and advantages in multiple key areas. The core layer is made of high-performance nylon (PA) material, which gives it excellent high-temperature resistance. It can withstand temperatures up to 150°C or even higher without deformation or melting, and perfectly adapts to various high-temperature processing and storage needs, such as food packaging, industrial heat sealing, steam sterilization and other scenarios. Through the carefully designed multi-layer structure, especially the perfect combination of the middle layer TIE (Tie Layer, adhesive layer) and the PA layer, the oxygen, water vapor and grease barrier capacity of the film is effectively improved, effectively extending the shelf life of the product and maintaining the freshness and quality of the contents. Both the outer and inner layers are made of polypropylene (PP) material, which not only enhances the tensile strength and tear resistance of the film, but also ensures good flexibility and processing adaptability. Whether it is an automatic packaging line or manual operation, it can be easily handled, reducing the breakage rate and improving production efficiency. All PP and PA materials are widely recognized environmentally friendly materials. This product was designed with sustainable development in mind, supports recycling and reuse, reduces environmental burden, and meets the pursuit of green packaging by modern enterprises. Multi-layer co-extrusion technology ensures that the film material has excellent transparency and glossiness while maintaining high strength and heat resistance, making the products in the package clearly visible, improving the display effect of the goods, and attracting consumers' attention. With its unique performance advantages, this 7-layer symmetrical co-extruded high-temperature film is widely used in food packaging (such as cooked food, baked products), pharmaceutical packaging, chemical packaging, agricultural greenhouse covering film and other fields, providing safe, efficient and reliable packaging solutions for various industries.
