Abstract
The utility model discloses a kind of packing box fresh-keeping for fresh-cut fruit, including box body, epiphragma and the fresh-keeping gas being filled between the box body and the epiphragma, the box body is followed successively by high-obstruction and pet layer from inside to outside, the epiphragma is followed successively by pet layer, printing layer, adhesive layer and anti-fog layer from outside to inside, and the box body is provided with peel ply with the epiphragma joint.The oxidation rate disclosed in the present application that fruit is slow down for the fresh-keeping packing box of fresh-cut fruit, extends freshness date, while having anti-droplet effect, prevents epiphragma surface from producing water droplet, at the same peel ply make it is easily peelable at the heat-sealing of box body and epiphragma.
Description
Technical field
The utility model is related to food packaging applications, more specifically, is a kind of packing box fresh-keeping for fresh-cut fruit.
Background technology
Fresh-cut fruit be fresh fruit is classified, arranged, is selected, is cleaned, is removed the peel, cutting, it is fresh-keeping and packaging etc. one
It is the product that product keeps fresh state after series of processes.
Fruit is handled through peeling, cutting etc., can be produced mechanical damage to fruit tissue, be destroyed original protection system
Quilt, induction of a series of biochemical reactions for being unfavorable for storage of fresh-cut fruit, such as enzymatic and non-enzymatic browning aggravation, cutting
Surface lignifying, the invasion of microorganism and breeding etc., cause the quality problems such as discoloration, spoiled, quality change, make its fresh-keeping difficulty
Greatly increase.
The fresh-keeping method of currently known fresh-cut fruit is being directly loadable into common poly- second after peeling and corning of fruits, cutting mostly
In the hermetic bag of alkene material or put it into the hard box body that polypropylene material is made, it is then general in the attached last layer of box surface
It is directly placed into the refrigerating chamber of 0-4 degree and is refrigerated after logical polyethylene preservative film.
The effect brought using both traditional processing methods is often not ideal.Fresh-cut fruit and vegetable is packed at both
Interior, the reaction such as oxidation, brown stain, the product under conditions of deepfreeze inevitably occur in packing box for fruit
Freshness date also simply has 2-3 days, and freshness date is very short.And the steam produced in the process can be attached on preservative film and form water
Drop, influences attractive in appearance, while the preservative film being attached on box body is not easy to tear opening, without too big commercial value.
Utility model content
Because prior art has above mentioned problem, the utility model proposes a kind of packaging fresh-keeping for fresh-cut fruit
Box, its object is to provide it is a kind of reduce fruit oxidation rate, prevent the packing box that occurs a large amount of water smokes on epiphragma, easily open,
It can effectively solve the problem that problems of the prior art.
The utility model solves the above problems by the following technical programs：
The application provides a kind of for the fresh-keeping packing box of fresh-cut fruit, including box body, epiphragma and is filled in the box
Fresh-keeping gas between body and the epiphragma, the epiphragma is followed successively by pet layer, printing layer, adhesive layer and antifog from outside to inside
Layer composition；The box body is followed successively by high-obstruction and pet layer from inside to outside；The epiphragma is sealed on the box body.
It is preferred that, the anti-fog layer and high-obstruction are ethylene-vinyl alcohol copolymer.
It is preferred that, the box body is provided with easy-peel absciss layer with the epiphragma joint, and the easy-peel absciss layer is ethylene-vinyl alcohol
Copolymer.
It is preferred that, the fresh-keeping gas is nitrogen, oxygen and the carbon dioxide mixed according to a certain percentage.
It is preferred that, the fresh-keeping gas is at least nitrogen, oxygen and carbon dioxide two kinds of gas therein.
It is preferred that, the pet layer thickness on the box body is 14 mils, and the thickness of the high-obstruction is 2 mils.
It is preferred that, the gross thickness of pet layer, printing layer and adhesive layer is 0.6 mil on the epiphragma, the anti-fog layer
Thickness is 2 mils.
Anti-fog layer on a kind of packing box fresh-keeping for fresh-cut fruit that the application is provided, its epiphragma is prevented with good
Droplet effect, prevents occurring water droplet on epiphragma, and the peel ply that its box body is provided with epiphragma joint is so that epiphragma is sealed with box body
Place is easily peelable, and the mixed gas being filled with its box body slow down the oxidation rate of fruit, extend the freshness date of fruit.
Brief description of the drawings
Fig. 1 is the structural representation of the packing box fresh-keeping for fresh-cut fruit；
Fig. 2 is the schematic diagram of the epiphragma of the packing box fresh-keeping for fresh-cut fruit；
Fig. 3 is the schematic diagram of the box body of the packing box fresh-keeping for fresh-cut fruit.
Embodiment
With reference to embodiment, the utility model is described in detail.
As described in Figure 1, Fig. 1 is the structural representation of the packing box fresh-keeping for fresh-cut fruit.It is a kind of shown in reference picture 1
The packing box fresh-keeping for fresh-cut fruit, including box body 1, epiphragma 2 and be filled between the box body 1 and the epiphragma 2
Fresh-keeping gas, the epiphragma 2 is heat-sealed on the box body 1.Wherein：
As shown in Fig. 2 schematic diagrames of the Fig. 2 for the epiphragma of the packing box fresh-keeping for fresh-cut fruit.The epiphragma 2 is by outer
Pet layer 201, printing layer 202, adhesive layer 203 and anti-fog layer 204 are inside followed successively by, wherein anti-fog layer 204 is ethylene-vinyl alcohol
The ratio of ethene is that 35%-40%, the ratio of vinyl alcohol are 60%-65% in copolymer, the ethylene-vinyl alcohol copolymer.
Ethylene-vinyl alcohol copolymer is to pass through the obtained product of saponification by ethylene-vinyl acetate copolymer, ethene-
Ethenol copolymer remains the good anti-droplet effect of ethylene-vinyl acetate copolymer, can effectively prevent to produce water on epiphragma 2
Mist, water droplet.
The barrier parameter of epiphragma 2 is in packing box disclosed in the present application：Oxygen transmission rate：Under the conditions of 23 DEG C of relative humidity 0%,
