CN201530958U - V-shaped corrugated paperboard for high-elastic packaging - Google Patents

Abstract

A V-shaped corrugated paperboard for high-elastic packaging comprises outer layer face paper, V-shaped corrugated core paper and inner layer face paper, wherein the V-shaped corrugated core paper is formed by at least two small V-shaped micro flutes, one side of each small V-shaped flute is attached with the face paper, and the other side is in a suspending state. The V-shaped corrugated paperboard increases a wave-shaped micro-flute structure on the basis of an existing V-shaped flute, increases the adhering points among the structure, the outer layer face paper and the inner layer face paper, and meanwhile, the adhering points of a plurality of micro flutes can scatter acting force transmitted from the face paper, the acting force is absorbed by the micro flutes, and the elasticity and the buffer performance of the paperboard are improved.

Description

A kind of high elasticity V-shaped corrugated board for package

Technical field

The utility model relates to a kind of corrugated board, specifically, relates to a kind of V-shaped corrugated board for package.

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.

The utility model content

The purpose of this utility model is in order to solve common V-arrangement corrugated board poor flexibility, shortcoming that bonding strength is low, to provide a kind of simple in structure, low cost of manufacture, the high elasticity V-shaped corrugated board for package that bonding strength, compression strength and shock-absorbing capacity are high.

The purpose of this utility model is achieved through the following technical solutions: it comprises outer facial tissue, nexine facial tissue, accompanies between described outer facial tissue and the nexine facial tissue by three to five little stupefied V-arrangement corrugating mediums that combine of little V-arrangement; 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 or three 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 utlity model has 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 the utility model embodiment.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, present embodiment comprises outer facial tissue 1, nexine facial tissue 3, accompanies between outer facial tissue 1 and the nexine facial tissue 3 by three little stupefied V-arrangement corrugating mediums 2 that combine of little V-arrangement.

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 each layer corrugating medium.

The utility model 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.

The utility model 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.

Claims (3)

1. a high elasticity V-shaped corrugated board for package comprises outer facial tissue, nexine facial tissue, it is characterized in that, accompanies between described outer facial tissue and the nexine facial tissue by three to five little stupefied V-arrangement corrugating mediums that combine of little V-arrangement; Little stupefied side of each little V-arrangement and facial tissue are bonding, and opposite side is in vacant state.

2. high elasticity V-shaped corrugated board for package according to claim 1 is characterized in that, described corrugating medium is two layers or three layers.
