A kind of high-elasticity impact-resistant corrugated cardboard
Technical field
The present invention relates to a kind of corrugated board, especially relate to a kind of high-elasticity impact-resistant corrugated cardboard.
Background technology
Corrugated board have shock resistance good, can print, in light weight, recyclable advantage such as use again, be widely used in fields such as the packing of product.
At present, generally the corrugated board of Shi Yonging generally constitutes the tri-wall corrugated paper plate structure by the outer facial tissue on upper and lower surface and the corrugated paper of centre, and intensity is low, poor impact resistance, and facial tissue easily comes off, and has limited the packed and transported of some specialities.Be to improve intensity and resistance to impact, normally increase the number of plies of corrugation, constitute paperboard structures such as five layers, seven layers or nine layers.Two watts of five layers of case of the present corrugated case of China account for the 75%-80% of sum, and single watt of three layers of case account for about 15%, and two watts of seven layers of case account for 5%.Corrugated board is in the great majority more than five layers, not only wastes resource, and the manufacturing cost height, has also increased the weight of environmental pollution, has reduced packaging space.
Summary of the invention
The object of the present invention is to provide the high high-elasticity impact-resistant corrugated cardboard of a kind of intensity.
The technical solution adopted for the present invention to solve the technical problems is: it comprises outer facial tissue, bottom facial tissue, is the regular pentagon corrugating media between outer layer surface paper and bottom facial tissue; Regular pentagon corrugating media and outer facial tissue lower surface and bottom facial tissue upper surface are bonding.
Described regular pentagon corrugating media, by independent one by one bonding composition of hollow regular pentagon paper web, each adjacent regular pentagon side is bonding mutually, and is that a upright regular pentagon and a handstand regular pentagon are staggered bonding.
Described outer facial tissue lower surface and regular pentagon corrugating media upper surface are bonding, and the crest of regular pentagon corrugating media is provided with and seamlessly transits.
Described bottom facial tissue upper surface and regular pentagon corrugating media lower surface are bonding, and the crest of regular pentagon corrugating media is provided with and seamlessly transits.
Described outer facial tissue and bottom facial tissue should be selected sand paper plate or brown paper for use, and the regular pentagon corrugating media is a fluting medium.
The present invention is owing to adopt the regular pentagon corrugating media, and the stressed back of regular pentagon is highly stable, makes this corrugated board have good resistance to impact; The formed void structure of regular pentagon corrugation paper mold makes this corrugated board have good shock resistance; Simultaneously, when regular pentagon corrugating media and corrugation facial tissue and base stock are bonding, one side, increased the peel strength of corrugated board, the facial tissue difficult drop-off because each is pentagonal all bonding with facial tissue.
Compared with prior art, the present invention has good resistance to impact and shock resistance; In the middle of transportation, when being subjected to external impacts, also be difficult for poking, can effectively protect commodity; Corrugated board peel strength height, the facial tissue difficult drop-off; Because single watt of three-decker and void structure can increase the corrugated board thickness of Unit Weight, realized helping economizing on resources the protection environment to light-weighted transformation; Simple in structure, in light weight, low cost of manufacture.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to Fig. 1, present embodiment comprises outer facial tissue 1, bottom facial tissue 3, is regular pentagon corrugating media 2 between outer layer surface paper 1 and bottom facial tissue 3; Regular pentagon corrugating media 2 is bonding with outer facial tissue 1 lower surface and bottom facial tissue 3 upper surfaces.
Outer facial tissue 1 and bottom facial tissue 3 are sand paper plate or brown paper, and regular pentagon corrugating media 2 is a fluting medium.
Regular pentagon corrugating media 2, by independent one by one bonding composition of hollow regular pentagon paper web, each adjacent regular pentagon side is bonding mutually, and is that a upright regular pentagon and a handstand regular pentagon are staggered bonding.
Outer facial tissue 1 lower surface and regular pentagon corrugating media 2 upper surfaces are bonding, bonding successively regular pentagon corrugating media crest 7, and top 6, crest 7 goes on successively Bottom facial tissue 1 upper surface and regular pentagon corrugating media 2 lower surfaces are bonding, and bonding order is the trough 4 of regular pentagon corrugating media, bottom 5, and trough 4 goes on successively ...
Among the present invention, regular pentagon corrugating media crest top 6 and outer facial tissue 1 are bonding, and regular pentagon corrugating media crest following 5 and bottom facial tissue 3 are bonding, have increased bond area, have improved the peel strength of corrugated board, the facial tissue difficult drop-off.
The present invention's high-elasticity impact-resistant corrugated cardboard is compared with traditional corrugated board; can increase the thickness of the corrugated board of Unit Weight, improve the shock resistance and the impact resistance of corrugated board, realize to light-weighted transformation; help economizing on resources the protection environment.
