The invention relates to a high-efficiency thawing and tenderizing type heat-insulating and bacteriostatic packaging bag and a preparation method thereof. A preparation method of an efficient thawing and tenderizing type heat-preservation and bacteriostatic packaging bag provides a preparation process of each layer, is particularly suitable for frozen foods, particularly meat products, increases the heat-preservation performance of the packaging bag in the transportation or storage process, promotes the tenderization of thawed meat, isolates the requirements of air exchange between the surrounding environment and the foods and the like, has good heat-preservation effect on meat-cooled products, and is suitable for large-scale popularization and application. |
