Abstract

The utility model relates to a corrugated board for a packing carton, comprising boxboard paper and corrugated paper. The utility model is characterized in that the corrugated board for a packing carton is composed of upper and lower two pieces of boxboard paper. A piece of corrugated paper with vertical corrugation, a piece of corrugated paper with left inclined corrugation and a piece of corrugated paper with right inclined corrugation are arranged between the upper and the lower boxboard paper. The five pieces of paper are bonded into a five-layer corrugated board. The corrugated structure is bonded in '*' shape. The packing carton made of the corrugated board has the advantages of compression resistance, impact resistance, increased stiffness, large thickness, large elastic force, large supporting force of each corner of the packing carton, uniform stiffness and no folded ditch. The damage of merchandise can be reduced, and the cost is decreased as imported paper is replaced by home-made paper. The corrugated structure is a network shape through bonding, so the dry time of corn starch adhesive is shortened, and the technological process is easy.

Description

Corrugated paperboard for packing carton

The utility model relates to a kind of Packaging Box corrugated board.

Now, the five layer paperboard Packaging Box that each carton factory of China is produced are two perpendicular stupefied structures, and the export packing carton mostly uses foreign paper to make.The carton made from two corrugated paper boards exists the compressive resistance inequality, and particularly laterally compressive resistance is poor, along the stupefied cardboard folding ditch that makes easily, influences cardboard and endures power.Because the thickness of cardboard, intensity, very power, elastic force, anti-impact force are poor, frangible commodity export is increased damaged, the outlet pottery carton that especially uses native paper to make, breakage rate is more outstanding.The carton that unit is produced is bonding with corn starch adhesive agent, exists the problem of not doing, and the employing drying chamber that has oven dry or artificial airing strengthen cost, prolong the carton production cycle.

The purpose of this utility model is to overcome above-mentioned weak point; a kind of cardboard that can improve the inherent quality of Packaging Box is provided; can make the Packaging Box of various different models; play the effect of protection commodity; and with native paper substituting import one paper; reduce the cost of Packaging Box, its structure is five layer of three corrugation, stupefied a kind of packing corrugated board to six sides.

The utility model is achieved in that a kind of Packaging Box is made up of boxboard and corrugated paper with corrugated board, it is characterized in that, the utility model is by last, following two boxboards, the centre is a perpendicular stupefied paper, the stupefied paper of left slanting, the stupefied paper of right slanting, be bonded into five-layers corrugated fiberboard, stupefied structure is " * " type, and is stupefied to being six direction, five layer paperboards that are bonded, very power is even for cardboard itself, do not roll over ditch, thickness increases and has elastic force, the Packaging Box of the various models of making can increase compressive resistance, because the increase of elastic force, externally impact can play cushioning effect, left slanting, right slanting stupefied to towards the case angle increased the very power and the support force at each case angle of carton again.

According to the packing needs of different commodity, can form the cardboard of different stupefied types, promptly the A type is stupefied, the C type is stupefied, Type B is stupefied, and its stupefied type combination is as follows:

A left side slanting: A, C, B, B, C

Perpendicular stupefied: B, B, B, B, B

Right slanting: A, A, A, C, C

For its stupefied type of supporting making carton makes up as follows:

Left tilted surface is stupefied: B, B, B, C

Right tilted surface is stupefied: A, C, B, C

Embodiment is described in further detail below in conjunction with (accompanying drawing):

Accompanying drawing 1 is a paperboard structure schematic diagram of the present utility model.

Accompanying drawing 2 is stupefied structural representations of the present utility model.

It is shown in Figure 2 to press Fig. 1, the Packaging Box corrugated board, be by a facial tissue, paper in one, five layer three of being bonded into of three stupefied paper is stupefied, stupefied cardboard to six sides, its structure is by facial tissue (1), the a left side stupefied paper of slanting (2), perpendicular stupefied paper (3), the right stupefied paper of slanting (4), in paper (5), with the cardboard that corn starch adhesive agent is bonded, make carton after, slanting is stupefied to towards the case angle, therefore the very power and the support force at each angle of carton have been increased, because the stupefied structure of cardboard is " * " type, very power is even for cardboard itself, does not roll over ditch, cal(l)iper increases and elastic force is arranged, the Packaging Box of the various different size models of making can increase compressive resistance, and the increase of elastic force can be alleviated outer impulsive force, stupefied bonding formation network bonding, so performance of ventilating is good, and shortens drying time, help technological process and production cycle.

Because the difference of stupefied type; role is also different, for reaching the purpose of protection commodity, stupefied group of can use different stupefied types; stupefied as the A type for stupefied greatly; can increase cal(l)iper and elastic force, and can alleviate outer impulsive force, Type B is stupefied to be little stupefied; can increase cardboard and endure power; play the resistance to compression effect, the C type is stupefied to be deck, regulates cal(l)iper.Be the needs of different commodity packagings, erecting stupefied is that Type B is stupefied, and left slanting is that A, C, Type B are stupefied, right tool is stupefied to be that A, C type are stupefied, and the stupefied structure of cardboard can be made into A, B, A type, C, B, A type, B, B, A type, B, B, C type, the cardboard of multiple stupefied type structures such as C, B, C type.

For supporting making carton also can adopt different stupefied types, be made into B, A type, B, C type, B, Type B, the cardboard of C, C type structure.

Because the change of stupefied type, stupefied structure makes corrugated board improve inherent quality, can use native paper import substitution paper fully, and play the effect of protection commodity.

The utility model has the advantages that:

1, rational in infrastructure, utilize the science of power to improve on the whole the inherent quality of corrugated board, the Packaging Box of the various different models made from this cardboard has resistance to compression, shock resistance, very power is big, good springiness is alleviated outer impulsive force, increases very power and the support force at each angle of Packaging Box, and very power is even for cardboard itself, does not roll over the characteristics such as ditch. Can reduce the commodity breakage rate.

2, replacing foreign paper with domestic paper, is that country saves foreign exchange, has reduced the cost of Packaging Box, and has created advantage for the development of domestic paper industry.

3, replace the yellow plate paper SMIS namely to reduce cost with the corrugation SMIS, alleviated again box weight.

4, since three differences stupefied to stupefied paper bonding after, stupefied structure is " * " type, so performance of ventilating is good, the middle stupefied moisture absorption effect that plays can be shortened drying time of corn starch adhesive agent, is conducive to technological process.
