High-Temperature Resistant PE Packaging for 121℃ Sterilization - China Suppliers & Factory Products

Color: Transparent
Material: Polyethylene
Features: This high-performance packaging film is specifically engineered for the 121℃ high-temperature retort sterilization process. It reliably withstands the rigors of a 121℃ retort environment without experiencing shrinkage or deformation. With impressive heat-sealing strength ranging from 22-28N/15mm, this packaging ensures a tight, leak-proof seal post-retort, while maintaining a tear resistance attenuation rate of less than 5%. Crafted from all-PE material, it features advanced barrier properties achieved through a multi-layer structural optimization that effectively blocks oxygen and water vapor, preventing secondary contamination after sterilization. Manufactured using a multi-layer co-extrusion process, the thickness deviation is meticulously controlled within 2%-4%, making it compatible with automatic retort packaging production lines and ensuring processing stability.
Application: Ideal for food packaging requiring 121℃ high-temperature sterilization, this film is suitable for a variety of products, including prepared dishes (like braised pork and pork with preserved vegetables), vacuum braised foods (such as braised chicken feet and sauced beef), canned alternatives (including canned fish and canned meat), and baby food supplements. It is particularly effective in retort sterilization packaging lines within food processing plants, batch production of prepared dish companies, and e-commerce room-temperature preserved food packaging. This product is especially advantageous for food applications requiring long-term room-temperature storage, leveraging 121℃ sterilization for safety assurance. The use of all-PE material aligns with environmental recycling needs, making it an ideal choice for sustainable packaging solutions from reputable China suppliers and factories.
