Water-absorbing sponge is a kind of low-density polyester-type foam done by polyurethane (polyurethanes), and polyurethane is raw
Most common a kind of high polymer material in work.Water-absorbing sponge has the characteristic such as good moisture absorption, insulation, heat-insulated, damping.
As shown in figure 5, the concrete structure of anti-condensation fresh-keeping layer of the present utility model is：Upper nonwoven layer 1 and lower non-woven fabrics
The periphery of layer 2 is connected with each other, and connected mode forms filled cavity between upper nonwoven layer 1 and lower nonwoven layer 2, filled out to sew up
Fill chamber and be located at middle part, water-absorbing sponge layer 3 is located in filled cavity, i.e., water-absorbing sponge layer 3 is sandwiched in into upper nonwoven layer 1 and lower non-woven fabrics
Between layer 2.Connection suture can also be increased at middle part, filled cavity is divided into multiple, polylith water-absorbing sponge layer 3 is respectively positioned at each
From filled cavity in.
For the thickness and weight part ratio of anti-condensation fresh-keeping layer, preferably selection is：The thickness of water-absorbing sponge layer 3 is elected as
The thickness of 0.6cm, upper nonwoven layer 1 and lower nonwoven layer 2 elects 0.2~0.3mm, nonwoven layer and water-absorbing sponge layer weight as
Amount part is compared for 1:8~12.
Anti-condensation fresh-keeping layer is in manufacturing process, two blocks of basically identical non-woven fabrics of preferred dimension, two pieces of non-woven fabrics difference
As upper nonwoven layer 1 and lower nonwoven layer 2, upper nonwoven layer 1 and lower nonwoven layer 2 are mutually aligned, first by upper nonwoven layer 1
Sewed up with three sides of lower nonwoven layer 2, reserve an opening, from the corresponding water-absorbing sponge layer 3 of size, by water-absorbing sponge layer
3 are put into from opening, finally sew opening.
The fruits and vegetables moisturizing packaging used currently on the market mainly has two major classes, when polyethylene freshness protection package (including common PE
Freshness protection package and compound PE freshness protection packages) packaging, second, foam case packing.This two class packaging has good moistening effect, but anti-caking
Dew effect is all extremely limited, and fruits and vegetables are packing because the breathing during storage fresh-keeping and temperature fluctuation produce a large amount of steam
Bag or packaging chamber interior wall condense into the globule (condensation), are then adhering to the surface of product, cause its local brown stain, microbial growth
It is and rotten, rotten.Common PE freshness protection package and bubble chamber have good moistening effect, but are unable to anti-condensation；Compound PE is fresh-keeping
Bag (including anti-condensation composite fresh-keeping bag) is to fill auxiliary material anti-caking added with a small amount of moisture absorption in inner wall section in freshness protection package manufacturing process
Dew, but practical application shows, and this anti-condensation effect is very limited, can only adsorb minimal amount of steam, the particularly fresh-keeping later stage
Effect is poor, with fruits and vegetables reality in the process of circulation caused by condensation amount ratio, do not reach the anti-condensation effects of preserving fruit and vegetable utilizing needs at all.
The lamination layer structure that the utility model is fabricated to using the powerful absorbent function of water-absorbing sponge can then solve this problem well.
Embodiment two：
As shown in Figure 3 and Figure 4, the difference distinguished only in the following areas of embodiment two and embodiment one：In foam case lid
11 middle parts are provided with air-vent 14, and anti-condensation fresh-keeping layer 13 seals air-vent 14.
The fixed form of anti-condensation fresh-keeping layer 13 is still with as in embodiment one, being fixed on the interior table of foam case lid 11
Face.The area of air-vent 14 need to be less than a quarter of the area of case lid, be to ensure the intensity of foam case lid 11, air-vent
14 be to allow the interior holding of case is certain to breathe freely.
User needs basis to be actually needed from the fruits and vegetables anti-condensation fresh-keeping packaging box structure in embodiment one, or from real
Apply the fruits and vegetables anti-condensation fresh-keeping packaging box structure in example two.
Anti-condensation fresh-keeping layer 13 of the present utility model can also be used alone, and its occupation mode is as follows：
Anti-condensation fresh-keeping layer is sheet, when in use, anti-condensation fresh-keeping layer is put in into fruit and vegetable food in plastic packaging bag
Surface, then packaging bag folding is sealed, the surface for being then directly put in fruit and vegetable food in case directly packed with carton, then by case
Mouth is sealed.Steam caused by the absorption fruits and vegetables breathing of anti-condensation fresh-keeping layer, condenses without being formed in product surface, keeps fruits and vegetables table
Face is dried, and can maintain water-in-bag balance-dividing.
Below process and the effect reached are used for the part of anti-condensation fresh-keeping layer of the present utility model：
Use process one：Cabbage heart (meeting storing quality requirement) after harvesting is loaded to the anti-condensation fresh-keeping packaging of the present invention
Case, back sealed box mouth is filled by specification, preserved 7~9 days under normal temperature (20~25 DEG C), cabbage heart surface water stain-free shape, color, smell and taste

Use process four：Lichee (meeting storing quality requirement) after harvesting is loaded to the anti-condensation fresh-keeping packaging of the present invention
Case, back sealed box mouth is filled by specification, preserved 8~10 days under normal temperature (20~25 DEG C), lichee surface water stain-free shape and brown stain,
Nutritional quality and flavor are basically unchanged, and than compareing (bubble chamber for not putting anti-condensation fresh-keeping layer), long fresh-keeping period extends 4~5 days.
Use process five：Lichee (meeting storing quality requirement) after harvesting is loaded into compound PE freshness protection packages, by tile
Anti-condensation fresh-keeping layer is put in the surface of lichee in packaging bag, then packaging bag is sealed into mouth, and (25~28 DEG C) preserve 7 at normal temperatures
~9 days, lichee surface water stain-free shape and brown stain, nutritional quality and flavor were basically unchanged, and (anti-condensation fresh-keeping layer is not put than control
Anti-condensation material), long fresh-keeping period extends 3~4 days.
Use process six：Lichee (meeting storing quality requirement) after harvesting is loaded into compound PE freshness protection packages, by tile
Anti-condensation fresh-keeping layer is put in the surface of lichee in packaging bag, then packaging bag is sealed into mouth, and (3~5 DEG C) preserve 35 at low temperature
~42 days, lichee surface water stain-free shape and brown stain, nutritional quality and flavor were basically unchanged, and (anti-condensation fresh-keeping layer is not put than control
Anti-condensation material), freshness date extend 10~15 days.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
