Packing case with moisture-proof function
Technical field
The utility model belongs to the packing case field, particularly a kind of corrugated-paper packaging box with moisture-proof function.
Background technology
The material day of wooden-box package is becoming tight, and the utilization rate of timber is lower, cost is higher, and with the wooden case that timber is made, shockproof properties is poor, and the parasitosis of timber evil also has influence on the quality of timber, the packing case that plastics or foam are made is difficult for reclaiming, and can cause serious environmental pollution, and no matter be the packing case that wooden case or plastics or foam are made, the casing of packing case is subject to easily the impact of temperature and deforms.Carton is more and more applied on the packing by people, and it is convenient light and handy, and cost is low, body is light, is convenient to loading and unloading and transportation.But the easy moisture absorption of the packing case of paper structure, fearness wet, and deform easily under the environment of humidity.
Summary of the invention
The utility model has designed a kind of packing case with moisture-proof function for the deficiencies in the prior art, can be damp proof preferably, guarantee intensity and the shape of casing, and can support preferably and locate goods.
The utility model is achieved through the following technical solutions:
Packing case with moisture-proof function, it comprises pallet, symmetrically arranged positive coaming plate and gusset plate, described positive coaming plate is arranged on the up and down both sides of pallet, the gusset plate is arranged on the left and right sides of pallet, it is characterized in that: described positive coaming plate and gusset plate comprise two-layer table paper, be provided with core paper between the described two-layer table paper, described core paper is the structure of corrugated, and the outer surface of described two-layer table paper is pasted with the plastics waterproofing layer.
Fill by hygroscopic material between the two-layer table paper of described positive coaming plate and gusset plate and the core paper, when breaking appears in the plastics waterproofing layer on the table paper, the hygroscopic material that arranges between table paper and the core paper can absorb the moisture content that enters packing case, prevent that moisture content from further spreading, guarantee on the one hand the stability of packing box structure, also guaranteed on the other hand the security of Bale Cargo.
Adopt glue bonding between described two-layer table paper and the core paper.
In sum, the beneficial effects of the utility model are: packing case described in the utility model has preferably humidity resistance, can carry out one to goods preserves preferably and supports, avoid goods in transportation, to be damaged, packing case described in the utility model has long service life simultaneously, can recycle and reuse, reduce wananty costs.
Description of drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the generalized section of gusset plate and positive coaming plate;
1 is the gusset plate among the figure, and 2 is positive coaming plate, and 3 is pallet, and 4 is core paper, and 5 are table paper, and 6 are the plastics waterproofing layer, and 7 is hygroscopic material.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The packing case with moisture-proof function as depicted in figs. 1 and 2, it comprises pallet 3, symmetrically arranged positive coaming plate 2 and gusset plate 1, described positive coaming plate 2 is arranged on the up and down both sides of pallet 3, gusset plate 1 is arranged on the left and right sides of pallet 3, it is characterized in that: described positive coaming plate 2 and gusset plate 1 comprise two-layer table paper 5, be provided with core paper 4 between the described two-layer table paper 5, described core paper 4 is the structure of corrugated, and the outer surface of described two-layer table paper 5 is pasted with plastics waterproofing layer 6.
Fill by hygroscopic material 7 between the two-layer table paper 5 of described positive coaming plate 2 and gusset plate 1 and the core paper 4, when breaking appears in the plastics waterproofing layer on the table paper, the hygroscopic material that arranges between table paper and the core paper can absorb the moisture content that enters packing case, prevent that moisture content from further spreading, guarantee on the one hand the stability of packing box structure, also guaranteed on the other hand the security of Bale Cargo.
Adopt glue bonding between described two-layer table paper 5 and the core paper 4.
In sum, the beneficial effects of the utility model are: packing case described in the utility model has preferably humidity resistance, can carry out one to goods preserves preferably and supports, avoid goods in transportation, to be damaged, packing case described in the utility model has long service life simultaneously, can recycle and reuse, reduce wananty costs.
