Abstract: The utility model discloses a kimchi fresh-keeping packaging bag in the field of food packaging, which comprises an outer bag made of an airtight film and an inner bag made of a water-proof and air-permeable film inside the outer bag. As well as the preservative made of a combination of alkaline material and oxygen absorbing material placed between the inner and outer packaging bags, the kimchi is placed in the inner packaging bag. The utility model utilizes the characteristics of high oxygen permeability and CO2 in the inner packaging bag to discharge the large amount of CO2 produced by the kimchi in the fermentation and the O2 brought into the packaging process in a timely and prompt manner from the kimchi, and is used for the preservation in the inner and outer packagings. The agent absorbs, thereby improving the quality of the Kimchi fermentation and eliminating the phenomenon of bags rising. The inner packaging adopts a composite film of paper, non-woven fabric and PE, CPP, which can not only breathe water, but also increase the strength of the packaging bag, which is conducive to mechanized automatic packaging.
