Abstract

The invention relates to an air-regulated fresh-keeping package, comprising a package body, wherein, the package body consists of an air-regulated fresh-keeping film, a breathable hydrophilic material layer and a breathable hydrophobic material layer from the outer layer to the inner layer in sequence, and the package body is provided with a sealing region on each predetermined part to combine the air-regulated fresh-keeping film, the breathable hydrophilic material layer and the breathable hydrophobic material layer; and the predetermined area of the package body is provided with a microscopic clearance structure region. The air-regulated fresh-keeping package can prolong the fresh-keeping and storing period for fresh vegetables and fruits by the air-regulated fresh-keeping function, and can provide an internal vegetables and fruits storage environment which can store accumulated water condensed by moisture generated by respiratory metabolism of the vegetables and fruits and provide high relative humidity.

Description

technical field [0001] The invention relates to a modified-atmosphere fresh-keeping bag with the functions of air-conditioning fresh-keeping and moisturizing, and the interface directly in contact with fresh fruits and vegetables is free from liquid accumulated water. Background technique [0002] In the early stage, if you want to prolong the preservation period of fruits and vegetables and maintain good quality, lowering the storage environment temperature is one way. Under low temperature environment, you can reduce the metabolic rate of living fruits and vegetables, and the oxidation consumption rate of organic sugar, starch and fat in fruits and vegetables will be reduced. Slow down, can delay the premature ripening and yellowing of fruits and vegetables. In addition, it was discovered decades ago that adjusting the concentration of oxygen and carbon dioxide in the air around fresh fruits and vegetables can also slow down their metabolic rate and prolong the lifespan an...
