Bio-based multifunctional freshness protection package

Abstract

The invention discloses a bio-based multifunctional freshness protection package, comprising a bag body, wherein an opening is formed in one side of the bag body, the bag body consists of a weight bearing layer, a blocking and separating layer and an adsorbing and freshness protecting layer from outside to inside, and the adsorbing and freshness protecting layer comprises a surface layer micro-foamed film body capable of slowing down water loss and adsorbing ethylene. As the freshness protection package consists of the weight bearing layer, the blocking and separating layer and the adsorbing and freshness protecting layer from outside to inside, a bio-based freshness protecting layer can not only lock water that is generated during the respiratory process of vegetables and fruits but also adsorb the ethylene that is generated during the respiration, the blocking and separating layer can reduce water loss, the weight bearing layer can buffer external extrusion so as to reduce damage, and therefore the freshness protection and storage time for the vegetables and the fruits is prolonged greatly, and meanwhile the freshness protection package has the advantages of simplicity and convenience for production and low cost.

Description

[0001] [technical field] [0002] The invention relates to a bio-based multifunctional fresh-keeping bag. [0003] [Background technique] [0004] When the fresh flowers, fruits and vegetables just picked are in the fresh-keeping bag, they will carry out aerobic respiration, and release water and ethylene continuously during the respiration process, in which ethylene will accelerate the ripening of fruits and vegetables. The function of holding water can not absorb ethylene, which will lead to the accelerated decay of fruits and vegetables in the fresh-keeping bags, which is not conducive to the long-term storage of fruits and vegetables. At the same time, some flowers and fruits and vegetables will quickly rot due to extrusion damage during stacking and transportation. [0005] [Content of the invention] [0006] The invention overcomes the disadvantages of the above technologies and provides a bio-based multifunctional fresh-keeping bag capable of absorbing ethylene produced...

AI Technical Summary

Problems solved by technology

[0004] When the fresh flowers, fruits and vegetables just picked are in the fresh-keeping bag, they will carry out aerobic respiration, and release water and ethylene continuously during the respiration process, in which ethylene will accelerate the ripening of fruits and vegetables. The function of retaining moisture can not absorb ethylene, which will cause the vegetables and fruits in the fresh-keeping bag to rot faster, which is not conducive to the long-term storage of fruits and vegetables. At the same time, some flowers and fruits and vegetables will rot quickly due to extrusion damage during stacking and transportation.
