Abstract
The utility model discloses a kind of fresh-keeping special paper bags of longan logistics, the special paper bag includes internal layer water accepting layer and waterproof outer layer, the waterproof outer layer lamination forms paper bag ontology on internal layer water accepting layer lateral surface, the paper bag ontology includes side and bottom surface, several air holes are equipped on the side, the side and bottom surface form accommodating chamber, the top edge bonding of the accommodating chamber.The white brown paper that the utility model uses has moisture-absorption characteristics and the design on bag body structure（Open up air hole）, because having leaching membrane layer on the outside of sack, therefore its intensity is unaffected after paper bag moisture absorption, and because of its permeation functions, therefore greatly ensure that the longan freshness in logistics transportation.
Description
Technical field
The utility model belongs to logistics preservation field, and in particular to a kind of fresh-keeping special paper bag of longan logistics.
Background technology
At present, fresh electric business is typically all vacuum formed box packaging for longan shipment, and the packaging is in longan logistics transportation
Fresh-keeping effect is bad, and cost is higher, once encountering the hot weathers such as summer, easily causes mouldy, fermentation（Alcohol smell）, not newly
It is fresh.If hot weather uses full cold chain transportation or bag on the rocks etc. to refrigerate shipment, logistics cost and packaging material cost certainly will be increased,
And effectual property limitation again.
Invention content
For problems of the prior art, the utility model provides a kind of fresh-keeping special paper bag of longan logistics, production
It is at low cost, and meet longan logistics transportation and breathe freely, the requirement of the moisture absorption.
To achieve the above object, the utility model uses following technical scheme：
A kind of fresh-keeping special paper bag of longan logistics, which includes internal layer water accepting layer and waterproof outer layer, described outer
Layer waterproof layer lamination forms paper bag ontology on internal layer water accepting layer lateral surface, and the paper bag ontology includes side and bottom surface, in institute
It states side and forms accommodating chamber, the top edge bonding of the accommodating chamber equipped with several air holes, the side and bottom surface.
The internal layer water accepting layer is white layers of kraft paper, and white brown paper is 50g/m2。
The waterproof outer layer is LDPE monofilms, and LDPE monofilms are 10g/m2。
The waterproof outer layer is PE monofilms.
The thickness of the waterproof outer layer is 14-16 μm.
The top edge passes through water base glue bond.
The diameter phi of the air hole is 2cm.
The air hole is uniformly distributed on side.
Any group of opposite side of the accommodating chamber bends inwards to form bending line.
Compared with prior art, the beneficial effects of the utility model are：
The white brown paper that the utility model uses has moisture-absorption characteristics and the design on bag body structure（It opens up ventilative
Hole）, because having leaching membrane layer on the outside of sack, therefore its intensity is unaffected after paper bag moisture absorption, and because of its permeation functions, therefore greatly protects
The longan freshness in logistics transportation is demonstrate,proved.In fresh logistics transportation, using the longan of this paper bag packing, then with general
Corrugated case makees outer packing shipment, and the fresh-keeping effect of 50hrs can be also reached in hot weather.

Specific embodiment
Embodiment 1
As shown in Figs 1-4, the fresh-keeping special paper bag of the present embodiment longan logistics, the special paper bag include 1 He of internal layer water accepting layer
Waterproof outer layer 2,2 lamination of waterproof outer layer form paper bag ontology, the paper bag ontology on 1 lateral surface of internal layer water accepting layer
Including side and bottom surface, several air holes 3 are equipped on the side, the side and bottom surface form accommodating chamber 4, the receiving
The top edge bonding of chamber 4.
Internal layer water accepting layer 1 is white layers of kraft paper in the present embodiment, and white brown paper is 50g/m2；Waterproof outer layer 2 is LDPE
Monofilm, LDPE monofilms are 10g/m2。
Preferably, the thickness of outer layer waterproof layer is any between 14 μm, 15 μm, 16 μm or 14-16 μm in the present embodiment
Numerical value.
Preferably, top edge passes through water base glue bond in the present embodiment.
As further preferred, the diameter phi of air hole 3 is 2cm in the present embodiment, and air hole 3 uniformly divides on side
Cloth.
As still more preferably, any group of opposite side of accommodating chamber 4 bends inwards to form bending in the present embodiment
Line.
Embodiment 2
Outer layer waterproof layer 2 is PE monofilms in the present embodiment, remaining scheme is the same as embodiment 1.
Although above-described embodiment makes the utility model specific descriptions, for those of ordinary skill in the art
For, it is understood that in disclosed in the utility model can be based within the spirit and scope for not departing from the utility model
Appearance is modified or is improved, these modification and improvement are all within the spirit and scope of the utility model.
