Abstract
The invention discloses a special raw paper for roof-shaped packing. The special raw paper comprises a surface layer, a core layer and a bottom layer which are arranged from top to bottom, wherein the surface layer and the bottom layer are made of bleached wood pulp, and the middle core layer is made of mechanical wood pulp, bleached wood pulp and papermaking broken paper. The surface layer, the core layer and the bottom layer are bonded in a neutral and acidic double-component glue applying mode. The special raw paper for roof-shaped packing accords with the environmental protection idea, realizes environmental protection requirements, contains no fluorescent brightening agents or any substances harmful to human bodies, and can be recovered after being used; and the surface layer, the core layer and the bottom layer are bonded in the neutral and acidic double-component glue applying mode, so the lactic acid resistance of paper is met.
Description
Technical field
The present invention relates to a kind of packaging for foodstuff paper using, particularly relating to a kind of roof bag dedicated raw paper for packing milk.
Background technology
Packaging for foodstuff paper using kind pattern gets more and more, even become the important symbol of environmental protection, in order to meet environmental protection concept, meet the requirement of environmental protection, the present invention proposes a kind of roof bag dedicated raw paper, pure wood pulp is adopted to manufacture paper with pulp, not containing fluorescent whitening agent and any harmful material, can also reclaim after a procedure, make them after completing the function of packaging, can " give up and not abandon ", thus fully demonstrate the feature of environmental protection.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of roof bag dedicated raw paper, not containing fluorescent whitening agent and any harmful material, can also reclaim after a procedure.
The present invention solves the problems of the technologies described above the technical scheme adopted to be to provide a kind of roof bag dedicated raw paper, wherein, be arranged as surface layer, sandwich layer and bottom from top to bottom, surface layer and bottom adopt bleached wood pulp to be made, and middle sandwich layer adopts groundwood pulp, bleached wood pulp and broken of manufacturing paper with pulp to be made.
Above-mentioned roof bag dedicated raw paper, wherein, described surface layer, between sandwich layer and bottom by neutral Plus acidic double base resin application methods bonding.
The present invention has following beneficial effect relative to prior art: roof provided by the invention bag dedicated raw paper, middle sandwich layer adopts groundwood pulp, bleached wood pulp and broken of manufacturing paper with pulp are made, broken of manufacturing paper with pulp is exactly the broken formed in this process of producing product, meet environmental protection concept, meet the requirement of environmental protection, not containing fluorescent whitening agent and any harmful material, can also reclaim after a procedure; Surface layer, between sandwich layer and bottom, adopt the bonding of neutral Plus acidic double base resin application methods, both met the anti-lactic acid effect of paper, and reach the object of technological break-through, and cost had been low, there are wide market prospects.
Accompanying drawing explanation
Fig. 1 is the structural representation of roof provided by the invention bag dedicated raw paper.
In figure:
1 surface layer 2 sandwich layer 3 bottom
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
In prior art, the domestic manufacturer also not having roof bag dedicated raw paper, market is monopolized by external competing product, and adopt the applying glue of rosin sizing agent unit at present in addition, especially yogurt packing box cannot reach antiacid effect, can not solve the problem that limit is oozed.
Roof provided by the invention bag dedicated raw paper, is arranged as surface layer 1, sandwich layer 2 and bottom 3 from top to bottom, and wherein, surface layer 1 and bottom 3 adopt bleached wood pulp to be made, and middle sandwich layer 2 adopts groundwood pulp, bleached wood pulp and broken of manufacturing paper with pulp to be made.Wherein, broken of manufacturing paper with pulp is exactly the broken formed in process of producing product.
In addition, described surface layer 1, between sandwich layer 2 and bottom 3 by neutral Plus acidic double base resin application methods bonding.
Roof provided by the invention bag dedicated raw paper, meets environmental protection concept, meet the requirement of environmental protection, not containing fluorescent whitening agent and any harmful material, can also reclaim after a procedure; Surface layer 1, between sandwich layer 2 and bottom 3, adopt the bonding of neutral Plus acidic double base resin application methods, both met the anti-lactic acid effect of paper, and reach the object of technological break-through, and cost had been low, there are wide market prospects.
Although the present invention discloses as above with preferred embodiment; so itself and be not used to limit the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when doing a little amendment and perfect, therefore protection scope of the present invention is when being as the criterion of defining with claims.
