A kind of modified V-shaped corrugated board for package
Technical field
The present invention relates to a kind of corrugated board, specifically, relate to a kind of modified V-arrangement corrugated board.
Background technology
The corrugated board packing container is compared with the packing container made from other materials, it is good to have shockproof properties, easily make, can print, in light weight, advantages such as intensity is high, recyclable regeneration, in packaging field, be widely used, as the packed and transported than breakables such as heavy articles and glass, porcelain, handicrafts such as refrigerator, air-conditioning, TV.
But the crest radius of existing V-arrangement corrugated board is little and sharp, and stupefied end face and facial tissue adhesive surface are narrow, cause bonding strength low, make behind the carton can the reduction carton intensity; And the V-arrangement corrugated board limit point that bears above cardboard that is under pressure is promptly destroyed later on; corrugation can not return to original state, does not have the effect of protection product, therefore; at present, the packing case that uses the V-arrangement corrugated board to make is mainly used in the product not high to packing instructions.Be the product in more effective protection sheet packing case, people often take the measure of filling expanded material in packing case, but this class expanded material mostly is plastic products, easily causes environmental pollution.U-shaped corrugation that shock-absorbing capacity is good and V-arrangement corrugation are combined into two stupefied corrugated boards, can improve the shock-absorbing capacity of cardboard, but like this, can make the casing volume become big, have reduced available space, have also increased cost simultaneously.
Summary of the invention
The objective of the invention is provides a kind of simple in structure, low cost of manufacture, the corrugated board that bonding strength, compression strength and shock-absorbing capacity are high in order to solve common V-arrangement corrugated board poor flexibility, shortcoming that bonding strength is low.
The objective of the invention is to be achieved through the following technical solutions: it comprises outer facial tissue, nexine facial tissue, and at least two little stupefied V-arrangement corrugating mediums that combine of (preferred three to four) little V-arrangement serve as reasons between outer facial tissue and the nexine facial tissue; Little stupefied side of each little V-arrangement and facial tissue are bonding, and opposite side is in vacant state.
Described corrugating medium can be V-arrangement fluting medium or brown paper, and facial tissue and lining paper can be boxboard.
The number of plies of described corrugating medium: can be individual layer, also can be more than two layers; Can also add sandwich paper between the two-layer corrugating medium.
Because the little V-arrangement that contains of each stupefied top is little stupefied all bonding with facial tissue (or in paper), the bonding point sum increases, and making the contact area increase of corrugating medium and facial tissue and lining paper has increased the bonding strength between each layer of cardboard body paper; Simultaneously the stupefied top of these little V-arrangements contacts with facial tissue, and when being subjected to the pressure in the external world, each is little stupefiedly can disperse a part of pressure, makes stupefied top can bear bigger pressure; In addition, these little V-arrangements can also absorb wherein the vibration that a part passes over, and vibratory response is postponed, it can be produced with the vibration that passes over once more offsets, thereby in and the partial vibration energy, increase the ability of corrugated board opposing foreign impacts.
Because described corrugating medium can be V-arrangement fluting medium or brown paper, facial tissue and lining paper can be boxboard, these all are the raw material of producing common fluting medium, so do not need to increase cost, can make the high corrugated board of bonding strength, compression strength and shock-absorbing capacity.
Compare with traditional V-arrangement corrugated board, the present invention have anti-seismic performance good, easily be automated advantages such as production, in light weight, low cost of manufacture.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of one embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, present embodiment comprises outer facial tissue 1, nexine facial tissue 3, is by three little stupefied V-arrangement corrugating mediums 2 that combine of little V-arrangement between outer facial tissue 1 and the nexine facial tissue 3.
Described corrugating medium is processed into by fluting medium or brown paper, and the facial tissue material is a boxboard.The number of plies of corrugating medium can be an individual layer, also can be more than two layers; Can also add sandwich paper between the two-layer corrugating medium.
The present invention's modified V-arrangement corrugated board can be used for making the carton of beer case, Beverage case, instant noodles case and packing precision instrument and high-grade electric equipment products.
In the process such as the high-grade electric equipment products of, packed and transported, when being subjected to external impacts, each is little stupefiedly can disperse a part of pressure, makes corrugated board can bear bigger pressure; In addition, these little V-arrangements can also absorb wherein a part of vibration that passes over, vibratory response is postponed, it can be produced with the vibration that passes over once more offsets, thereby in and the partial vibration energy, increase the ability of corrugated board opposing foreign impacts, make the unlikely packing case of electric equipment products be subjected to external impacts and damage.
Modified V-arrangement corrugated board of the present invention, only need change the shape of corrugation roller, just can need not to increase separately other equipment by existing corrugated paper board production line production.
