A kind of environmental protection package corrugated board with isosceles trapezoid and semicircular structure
Technical field
The utility model relates to wrapping paper technology, is a kind of environmental protection package corrugated board with isosceles trapezoid and semicircular structure specifically.
Background technology
Corrugated board is a kind of important packaging material, is made into packing case, for packaging, storage and the transport of large-sized object.In prior art, corrugated board is generally made of brown paper and fluting medium, also claims papery corrugated board, need to consume a large amount of paper woods.
But traditional paper technology at least has the following disadvantages:
(1) primary raw material of papermaking is the wood pulp that trees are made, and has consumed the forest reserves of a large amount of preciousnesses, is a key factor that causes earth ecology unbalance;
(2) paper-making process need consume a large amount of water resources and the energy;
(3) paper-making process discharges a large amount of waste water,waste gas and industrial residue, contaminated environment and harm humans health.
At present, the corrugated board generally using generally forms three-decker by the outer facial tissue on upper and lower surface and middle corrugated paper, and intensity is low, and poor impact resistance has limited the packed and transported of some products.Normally increase the number of plies of corrugation in order to improve the resistance to impact of corrugated board, form five layers or seven-layer structure.But these class methods are limited to resistance to impact and the compression strength of raising corrugated board, not only waste resource but also reduced packaging space.
In addition, papery corrugated board low strength, easily breaks, yielding, and the shortcoming such as easily damage by worms, it is restricted in international trade, and the cardboard Costco Wholesale of sandwich construction is high, is unfavorable for reducing packing cost.
Utility model content
The purpose of this utility model is to overcome the deficiency that above prior art exists, and a kind of simple in structure, low cost of manufacture is provided, has high strength, impact resistance is good, folding resistance to tearing is good, waterproof insectproof moth, compression strength is high, shock-absorbing capacity the is good environmental protection package corrugated board with isosceles trapezoid and semicircular structure.
In order to achieve the above object, the utility model by the following technical solutions: a kind of environmental protection package corrugated board with isosceles trapezoid and semicircular structure, comprises outer facial tissue, isosceles trapezoid corrugating media, semicircle corrugating media and bottom facial tissue; Wherein, outer facial tissue lower surface arranges even some isosceles trapezoid corrugating medias, and isosceles trapezoid corrugating media lower surface correspondence arranges semicircle corrugating media, and semicircle corrugating media lower surface arranges bottom facial tissue.
Described outer facial tissue, isosceles trapezoid corrugating media, semicircle corrugating media and bottom facial tissue are foaming calcium carbonate synthetic paper.
The span of described isosceles trapezoid corrugating media and semicircle corrugating media equates.
Groove trend and the semicircle corrugating media Special composition parallel relation of described isosceles trapezoid corrugating media, the crest of isosceles trapezoid corrugating media trough and semicircle corrugating media is on same vertical plane.
The height of described isosceles trapezoid corrugating media and semicircle corrugating media is identical.
The hypotenuse of described isosceles trapezoid corrugating media and horizontal plane angle are 30 ~ 70 °.
Also comprise inner paper, inner paper is located between isosceles trapezoid corrugating media and semicircle corrugating media.
The utility model, with respect to prior art, has following advantage and effect:
1, the utility model has adopted and has comprised outer facial tissue, isosceles trapezoid corrugating media, semicircle corrugating media and bottom facial tissue; Wherein, outer facial tissue lower surface arranges even some isosceles trapezoid corrugating medias, isosceles trapezoid corrugating media lower surface correspondence arranges semicircle corrugating media, semicircle corrugating media lower surface arranges bottom facial tissue, has simple in structure, low cost of manufacture, has high strength, the feature such as impact resistance is good, folding resistance to tearing is good, waterproof insectproof moth, cost is low, compression strength is high, shock-absorbing capacity is good.
2, the good calcium carbonate synthetic paper of the utility model employing feature of environmental protection is raw material, is conducive to ecological, environmental protective, and the cost of material is low, is convenient to processing and fabricating, is beneficial to and reduces production costs and promote, and on the other hand, product degradable, is beneficial to recovery.
3, the utlity model has high barrier, waterproof and dampproof, the resistance to advantage such as damage by worms.
4, the utility model has adopted isosceles trapezoid corrugating media, semicircle corrugating media, has resistance to compression and buffer structure, and compression strength is high, and impact resistance is good.
5, the utility model applicability is strong, can be made into packaging, storage and the transport of packing case for large-sized object.

Detailed description of the invention
For ease of it will be appreciated by those skilled in the art that the utility model is described in further detail below in conjunction with drawings and Examples.
embodiment 1:
As shown in Figure 1: a kind of environmental protection package corrugated board with isosceles trapezoid and semicircular structure, comprises outer facial tissue 1, isosceles trapezoid corrugating media 2, semicircle corrugating media 4 and bottom facial tissue 5; Wherein, outer facial tissue 1 lower surface arranges even some isosceles trapezoid corrugating medias 2, and isosceles trapezoid corrugating media 2 lower surface correspondences arrange semicircle corrugating media 4, and semicircle corrugating media 4 lower surfaces arrange bottom facial tissue 5.
Outer facial tissue 1, isosceles trapezoid corrugating media 2, semicircle corrugating media 4 and bottom facial tissue 5 in the present embodiment is foaming calcium carbonate synthetic paper, and the present embodiment adopts 250~400g/m
2foaming calcium carbonate synthetic paper, foaming calcium carbonate synthetic paper by granulation, foam, extrude, flow calendering technology and make, each layer paperboard is composited under high temperature fused state.
Isosceles trapezoid corrugating media 2 in the present embodiment and the span of semicircle corrugating media 4 equate, groove trend and the semicircle corrugating media 4 Special composition parallel relation of isosceles trapezoid corrugating media 2, the crest of isosceles trapezoid corrugating media 2 troughs and semicircle corrugating media 4 is on same vertical plane, and isosceles trapezoid corrugating media 2 is identical with the height of semicircle corrugating media 4.
The hypotenuse of isosceles trapezoid corrugating media 2 and horizontal plane angle are 30 ~ 70 °, and the angle in the present embodiment is 45 °, stupefied to consistent to semicircle corrugating media 4 of isosceles trapezoid corrugating media 2 stupefied.
