Abstract
The utility model discloses a case piece, including first facial tissue layer, second facial tissue layer and the corrugated paper layer in first facial tissue layer and second facial tissue layer, first facial tissue layer and second facial tissue layer separately dorsad corrugated paper layer's one side cover and to have the oil paper, be provided with the layer that absorbs water between second facial tissue layer and the corrugated paper layer. An object of the utility model is to provide a case piece, its advantage lies in the utility model discloses be suitable for extensively, can play waterproof effect effectively.
Description
Technical field
The utility model relates to a kind of field of packaging material, and more particularly, it relates to case sheet.
Background technology
Case sheet is mostly for packaging, and be of wide application, demand is also increasing, make packing case case sheet used primarily of corrugated paper, facial tissue and in paper composition.The watertight composition of case sheet of the prior art only does surface treatment, outside on surface smear, is coated with one deck watertight composition.
At present, disclose the Chinese patent waterproof tensile packing board that the patent No. is CN201310529231.7 on the market, comprise corrugated paper board layer, corrugated paper board layer upper surface is coated with PVC waterproof film layer and facial tissue layer from the bottom up respectively, corrugated paper board layer lower surface is coated with nylon layer, paraffin paper water barrier, inner ply of paper from top to bottom respectively.
PVC waterproof film layer in this patent is equivalent to watertight composition, due to long-time and contacting external air, along with the growth of time can be slowly hardening, last until aging, sclerosis, when case sheet bend slightly, deformation just can dry and cracked, come off, so that water vapor permeable is to case sheet internal layer, i.e. corrugated layer, cause corrugated layer to make moist softening, so lost efficacy, do not reach waterproof effect.Under wet weather, moisture can be entered in each layer paper of cardboard by facial tissue, and the intensity of cardboard is reduced greatly, and relates to the number of plies and material is more, and production cost is high.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of case sheet, and its advantage is that the utility model can waterproof effectively.
For achieving the above object, the utility model provides following technical scheme:
A kind of case sheet, comprise first surface ply of paper, the second facial tissue layer and the corrugated layer in first surface ply of paper and the second facial tissue layer, described first surface ply of paper and the second facial tissue layer separately dorsad the one side of corrugated layer be coated with oilpaper, be provided with water accepting layer between described second facial tissue layer and corrugated layer.
By adopting technique scheme, oilpaper adopts more tough body paper, coat tung oil or other drying oil are made, there is folding and water resistance, pvc waterproof pad pasting and oilpaper serve the effect of a heavy waterproof and double waterproof respectively to the utility model, its water resistance of the utility model is strengthened greatly, and service life also extends to some extent, and oilpaper price is economical, and production cost is low.
The utility model is set to further: described water accepting layer adopts hard foam to make.
By adopting technique scheme, can make the utility model in the impaired situation of pvc waterproof pad pasting, water accepting layer also has certain water absorbing capacity, prevent water smoke, moisture from directly invading inside of the present utility model, as corrugated layer, and hard foam except Function and operation own can also to the structural strength of case sheet itself play more stable, firmly, reliably act on.
The utility model is set to further: described pvc waterproof pad pasting and be provided with printed layers between first surface ply of paper and the second facial tissue layer.
By adopting technique scheme, the utility model provides case sheet, and its advantage is the intrusion that can prevent steam, fog from most surface and case sheet internal layer, plays duplicate protection, to such an extent as to destroys physique structure and the support degree of corrugated paper.
Below in conjunction with Figure of description, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the sectional view of this practical trunk sheet embodiment.
Reference numeral: 1, first surface ply of paper; 2, the second facial tissue layer; 3, corrugated layer; 4, pvc waterproof pad pasting; 5, printed layers; 6, water accepting layer; 7, oilpaper.
Detailed description of the invention
With reference to Fig. 1, the utility model case sheet embodiment is described further.
A kind of case sheet, comprise first surface ply of paper 1, second facial tissue layer 2 and the corrugated layer 2 in first surface ply of paper 1 and the second facial tissue layer 2, the one side of described first surface ply of paper 1 and the respective corrugated layer 2 dorsad of the second facial tissue layer 2 is coated with oilpaper 7, is provided with water accepting layer 6 between described second facial tissue layer 2 and corrugated layer 2.
In a particular embodiment, oilpaper 7 adopts more tough body paper, coat tung oil or other drying oil are made, there is folding and water resistance, pvc waterproof pad pasting 4 and oilpaper 7 serve the effect of a heavy waterproof and double waterproof respectively to the utility model, its water resistance of the utility model is strengthened greatly, and service life also extends to some extent, and oilpaper 7 price is economical, and production cost is low.
Described water accepting layer 6 adopts hard foam to make.Such setting can make the utility model in the impaired situation of pvc waterproof pad pasting 4, water accepting layer 6 also has certain water absorbing capacity, prevent water smoke, moisture from directly invading inside of the present utility model, as corrugated layer 2, and hard foam except Function and operation own can also to the structural strength of case sheet itself play more stable, firmly, reliably act on.Described pvc waterproof pad pasting 4 and be provided with printed layers 5 between first surface ply of paper 1 and the second facial tissue layer 2.
In a particular embodiment, hard foam is processed into primarily of production colour polyurethane sponge, imitative polyester sponge, MR net silk floss, renewable sponge and random hole sponge etc., packs for instrument.
In sum; by adopting technical scheme, the utility model provides a kind of case sheet, and its advantage is the intrusion that can prevent steam, fog from most surface and case sheet internal layer; play duplicate protection, to such an extent as to destroy physique structure and the support degree of corrugated layer 3.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
