Abstract

A kind of bag with square bottom of disclosure, including bag, the bag upper end open, it is characterised in that the bag includes side and bottom surface, the side is four vertical planes, the side of the vertical plane is bonded two-by-two successively, and the bonding place forms seam side, and the seam side is convex to set outside bag, the vertical plane lower end folds and hotly joins to form the bottom surface, and the place's of hotly joining formation hotly joins line.It is the bag with square bottom load-bearing, wear-resisting good with moisture effect.

Description

A kind of bag with square bottom

Technical field

The application is related to industrial packaging field, and in particular to plant bag with square bottom.

Background technology

Bag with square bottom as packing container, due to its contain taken before article small volume, light weight, storage convenient transport and by It is widely applied to every field.The bag with square bottom sealing used at present is poor, easily occurs breaking off the base and Seepage, wearability and holds Principal characteristic is poor, when bag with square bottom is stood up, and bag bottom contacts moisture-sensitive influence with desktop, ground and takes up amount of substance.

Utility model content

In view of this, a kind of bag with square bottom of the application is the bag with square bottom load-bearing, wear-resisting good with moisture effect.

In order to achieve the above object, the application provides following technical scheme：

A kind of bag with square bottom, it includes bag, and the bag upper end open, the bag includes side and bottom surface, the side Face is four vertical planes, and the side of the vertical plane is bonded two-by-two successively, and the bonding place forms seam side, the seam While being convex to set outside bag, the vertical plane lower end folds and hotly joins to form the bottom surface, and the place's of hotly joining formation hotly joins line.

It is preferred that, the side and the bottom surface include successively from inside to outside：PE protection film layers, layers of kraft paper, PE are protected Cuticular layer and ink layer；Pass through between the PE protection film layers, the layers of kraft paper, the PE protection film layers and the ink layer Adhesive is bonded.

It is preferred that, the line that hotly joins is that double eight words for hotly joining line connection by a word hotly join cable architecture.

It is preferred that, the bottom surface is plane quadrilateral.

It is preferred that, the bottom surface is rectangle.

It is preferred that, the profile height is 180~750mm.

It is preferred that, the junction low side of two sides of arbitrary neighborhood is respectively provided with square corner protector.

It is preferred that, the bag also includes inner liner, and the inner liner is bonded on the bottom surface.

It is preferred that, the inner liner and the bottom shape are in the same size.

It is preferred that, damp-proof layer is provided between the inner liner and the bottom surface.

Herein described vertical plane lower end folds and hotly joins to form the bottom surface, it is to avoid the side and bottom surface connection Place's leakage takes up thing, lift-off seal, while double eight words that a word hotly joins line connection hotly join setting on the bottom surface of cable architecture The inner liner, load-bearing stress point is uniformly distributed, and adds the intensity of bag with square bottom load-carrying.

The layers of kraft paper upper and lower surface of herein described side and the bottom surface is provided with the PE protection film layers, described The damp-proof layer is provided between inner liner and the bottom surface, can be effectively moistureproof；Set the PE protection film layers, the inner liner with The square corner protector is combined, and effectively improves bag with square bottom wearability.

Compared with prior art, its detailed description is as follows by the application：

Structure is novel, and load-bearing, abrasion resistant effect are good；

The application layers of kraft paper upper and lower surface is provided with PE protection film layers, and damp-proof layer is combined, and effectively protection takes up thing and do not made moist；

It is that double eight words for hotly joining line connection by a word hotly join cable architecture that bottom surface, which hotly joins line, it is to avoid bottom surface material is repetitively folded, It is cost-effective.

Fig. 2 is bag with square bottom bottom sectional view described in the utility model.

Embodiment

In order that those skilled in the art more fully understands the technical scheme of the application, with reference to specific embodiment pair The application is described in further detail.

A kind of bag with square bottom, it includes bag, the bag upper end open, and the bag includes side 1 and bottom surface 2, described 1 is four vertical planes sideways, and the side of the vertical plane is bonded two-by-two successively, and the bonding place forms seam side 3, described Seam side 3 is convex to set outside bag, and the vertical plane lower end folds and hotly joins to form the bottom surface 2, and the place of hotly joining, which is formed, scalds Zygonema 4.The side 1 and the bottom surface 2 include successively from inside to outside：PE protection film layers 5, layers of kraft paper 6, PE protection film layers 5 and ink layer 7；Pass through between the PE protection film layers 5, the layers of kraft paper 6, the PE protection film layers 5 and the ink layer 7 Adhesive is bonded.The line 4 that hotly joins is that double eight words for hotly joining line connection by a word hotly join cable architecture.The bottom surface 2 is plane four Side shape, the plane quadrilateral is rectangle, and the height of side 1 is 180~750mm, the company of the side 1 of arbitrary neighborhood two The place's of connecing low side is respectively provided with square corner protector 8, and the bag also includes inner liner 9, and the inner liner 9 is located on the bottom surface 2, The inner liner 9 is consistent with the shape size of bottom surface 2, and damp-proof layer 10 is provided between the inner liner 9 and the bottom surface 2.

It the above is only the preferred embodiment of the application, it is noted that above-mentioned preferred embodiment is not construed as pair The limitation of the application, the protection domain of the application should be defined by claim limited range.For the art For those of ordinary skill, do not departing from spirit and scope, some improvements and modifications can also be made, these change Enter and retouch the protection domain that also should be regarded as the application.
