Abstract

The utility model discloses a fruit fresh keeping bag, which is characterized in that a sealing strip (2) is arranged in the top end of a bag body (1) which is divided into a fresh keeping layer (11), a moisture preserving and adsorbing layer (12) and a fresh keeping and ventilating layer (13) in sequence from outside to inside, the fresh keeping layer (11) is provided with ethylene adsorbent (121), and the surface of the fresh keeping and ventilating layer (13) is provided with ventilating small holes (131). The fruit fresh keeping bag can be used for effectively solving the problem that moisture easily runs off and fresh is not easy to keep after fruits are picked, has the advantages of simple structure, low manufacturing cost and convenience in operation, has very strong practicability and popularization and application prospect and can be widely applied to the industry of fresh keeping of postharvest fruits.

Description

Fruit fresh-preservation bag

Technical field

The utility model relates to a kind of fruit packaging field, specifically refers to a kind of Fruit fresh-preservation bag.

Background technology

Fruit is still life entity alive after harvesting, for maintaining its vital movement, is still carrying out respiration in the storage of fruit and transportation, produces moisture and ethene, moisture evaporation causes fruit dehydration to wilt, and gathering, minute grade packaged, storage transportation and arriving in the whole logistics progress in customer's hand, if dealt with improperly, will cause damage, and ethene is called the plant hormone that accelerates the ripening, it is a kind of natural metabolism thing that in fruit body, privileged site produces, the physiology course that can cause other position cell changes, high ethylene concentration is accelerated the respiration of fruit, ripe and aging course is accelerated, its ability of resisting various pathogens also declines thereupon, and postharvest disease has certain infectiousness conventionally, therefore easily cause large quantities of fruit rots, the storage and the transportation fresh-retaining that are unfavorable for fruit, therefore at a fresh-keeping middle reply fruit, carry out rationally suitable Preservation Treatment and the strict concentration of controlling ethylene gas, make its impact on fruit drop to minimum.

In developed country, have its loss of storage ， developing country that 10%-20% fresh fruit is lost in after adopting but up to the annual loss of 40%-50%， China, can reach 30,000,000,000 yuan, and cause commodity of low grade, the market competitiveness is poor.Conventional traditional freshness protection package is netted in the market, and it can only play the effect of fruit and fruit isolation, avoids pathogen to infect, but it can not extend the fruit freshness preserving phase and prevent moisture loss by actv., can not play good fresh-keeping effect.

Utility model content

The purpose of this utility model provides a kind of water loss, good Fruit fresh-preservation bag of fresh-keeping effect of preventing.

For achieving the above object, a kind of Fruit fresh-preservation bag of the utility model, bag is equipped with sealing band in top, and described bag is divided into fresh-keeping layer, moisturizing adsorbed layer and fresh-keeping air-permeable layer from outside to inside successively, wherein moisturizing adsorbed layer is provided with ethene adsorbent, and fresh-keeping air-permeable layer surface is provided with small ventilating holes.

The material of described fresh-keeping layer and fresh-keeping air-permeable layer is polyvinylchloride.

The material of described moisturizing adsorbed layer is hygenic towelette.

The material of described seal is double faced adhesive tape.

The utility model has adopted after said structure, because fresh-keeping layer can carry out moisturizing to institute's Storage of Fruits, avoids dehydration, can play fruit and isolation really, avoids plucking rear pathogen and spreads; Fresh-keeping air-permeable layer and moisturizing adsorbed layer can adsorb the ethene producing in fruit metabolic process, and the fruit after plucking is effectively extended to the freshness date between shelf life; The utility model is simple in structure simultaneously, and cost is low, easy to operate, and efficiency is high, has very strong practicality and popularizing application prospect, can be widely used in fruit freshness preserving industry.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the generalized section of the utility model bag.

In figure: the fresh-keeping layer of 1 bag 11 12 moisturizing adsorbed layer

Fresh-keeping air-permeable layer 131 small ventilating holes of 121 ethene adsorbent 13

2 sealing bands.

The specific embodiment

Below in conjunction with accompanying drawing 1, Fig. 2, the specific embodiment of the present utility model is described in further detail.

A kind of Fruit fresh-preservation bag of the present utility model, bag is equipped with sealing band 2 in 1 top, bag is divided into fresh-keeping layer 11, moisturizing adsorbed layer 12 and fresh-keeping air-permeable layer 13 from outside to inside successively, and wherein moisturizing adsorbed layer 12 is provided with ethene adsorbent 121, and fresh-keeping air-permeable layer surface is provided with small ventilating holes 131; Wherein the material of fresh-keeping layer 11 and fresh-keeping air-permeable layer 13 is polyvinylchloride, and the material of moisturizing adsorbed layer 12 is hygenic towelette, and the material of seal 2 is double faced adhesive tape.

Principle of work of the present utility model is, by waiting after harvesting, wants fresh-keeping fruit put into bag, tears the double faced adhesive tape sealing band on bag top off, and direct sealing, preserves.

The above is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any those skilled in the art, within not departing from the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
