When it comes to high-temperature resistant cooking bags standard, I believe many people do not understand it. Today, Jiuzhi Plastics Network Xiaobian summarizes the standards for high temperature resistant cooking bags, as follows:
China's high temperature retort pouch product standard, the earliest is GB10004-1988 "polyester (PET) aluminum foil (AL) polypropylene (CPP) composite film bag", the standard; 隹 material structure is only three layers of PE / AL / One type of CPP, the cooking conditions are limited to 121 ° C · 40 min.
After ten years, it was revised to G810004-1998 "Retort-resistant composite film and bag". The material structure of the product has been expanded, including PET/CPP, PA/CPP two-layer transparent type and PET/AL/CPP, PA. The /AL/CPP three-layer opaque type and the PET/PA/CPP three-layer transparent type, as well as the PET/AL/PA/CPP four-layer opaque type.
In terms of the physical and mechanical properties of the product, the three items of the medium resistance, the peeling force after cooking and the heat sealing strength after cooking were added, and the original oil resistance project was eliminated, highlighting the practical use of the product for high temperature cooking. Sex. After being revised again in 2002, the high-temperature retort pouch was included in the standard of "Composite film for packaging, bag general rule". This latest standard was approved in Guiyang at the end of December 2002, and the draft was officially confirmed. text.
