Problems solved by technology

However, when the deoxygenation bag is placed in the food packaging bag, there is often a situation of accidental leakage, resulting in food contamination. In order to make it difficult to leak, the deoxidation bag in the prior art generally fills the deoxidizer in the bag relatively satura

Embodiment 1

[0043] see figure 1 , a transit-type externally controlled deoxygenation package for food preservation, comprising a package body 1, the left and right outer ends of the package body 1 are fixedly connected with an outwardly extending hard sheet 2, and the outer edge of the outwardly extending hard sheet 2 is fixedly connected with a limit strip 3 .

[0044] see figure 2 , the arrow in the figure indicates the moving direction of oxygen, and the package body 1 includes an outer non-woven fabric layer 11 and an inner material hard layer 12 positioned inside the outer non-woven fabric layer 11, and the inner material hard layer 12 is filled with a deoxidizer, and the deoxidizer is in the The filling degree in the hard layer 12 of the inner material is 70-85%, so that the deoxidizer has enough space to move in the hard layer 12 of the inner material. When the food packaging bag is transported or taken by the user, the deoxidizer The inside of the deoxidizer bag can move to a c...

Abstract

The invention discloses a transfer type external control deoxidation bag for food fresh keeping, and belongs to the field of food fresh keeping. When the transfer type external control deoxidation bag for food fresh keeping is used, oxygen in a packaging bag sequentially passes through a transfer ventilation cylinder and an air transfer cavity along gaps between outward-extending hard pieces, and enters an inner material containing hard layer and is absorbed by a deoxidation reagent; compared with the prior art, deoxidation reagent particles need to reversely penetrate through a path where oxygen enters and then leak, so that the condition of accidental leakage of the deoxidation bag is effectively avoided under the condition that the gas circulation is not influenced; and furthermore, the deoxidation bag is filled with the deoxidation reagent in an unsaturated manner, so that the deoxidation bag has enough space to move in the inner material containing hard layer, when a food package is transported or taken by a user, the deoxidation reagent can move to a certain degree in the deoxidation bag, so that the absorbing effect of the deoxidation reagent on oxygen in the food package is better, and the deoxidation efficiency is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of food preservation, and more specifically relates to a transit type externally controlled deoxygenation bag for food preservation. Background technique [0002] In order to protect the original flavor of food and extend the shelf life, the modern food industry mainly adds food additives, the most commonly used is antiseptic preservative technology, and preservatives are generally divided into internal control antiseptic additives and external control preservatives. [0003] External control preservatives generally include a new class of packaging materials that are generally used in vacuum packaging (VP), controlled atmosphere packaging (CAP), and modified atmosphere packaging (MAP). A packaging microenvironment that is conducive to the long-term preservation of products. Since these materials often have ecological functions, they are called active packaging materials, such as oxygen-removing active packaging, steri...
