Abstract

The utility model discloses a paper bag which comprises a body formed by enclosing a bottom surface and a lateral surface, wherein the lateral surface comprises at least two paper layers and an inner film layer from outside to inside in sequence, and the paper layers and the inner film layer are sequentially and partially adhered. The bottom surface covers the lower end of the lateral surface and is connected with the lateral surface in sewing mode through an easy-pull line. Compared with the prior art, the paper bag has the advantages that the bottom of the paper bag can be filled with heavy diamond materials with irregular shapes, can ensure that the bag body and the bottom of the paper bag cannot be damaged when the materials are filled in the paper bag, and is moisture-proof when being used for storing the materials after material filling is completed.

Description

Paper bag

Technical field

The utility model relates to a kind of paper bag.

Background technology

At present, in the development along with paper bag packing field, market, requirement to coated paper envelope is also more and more higher, structure to paper bag is also of all kinds, when the quality of material of paper bag can very heavy, the profile of its material is the rhombus of very irregular, prevents again the material moisture regain that can is good, so just to the bag body of paper bag and tensile strength and the comprehensive raising of anti-soak properties of bottom.Paper bag structure in the past is just for granular material and granule materials design, and its speed of only requiring can is fast, and the profile of filled paper bag is needed square-folded, and the profile of its paper bag Founder is moved conveniently during overlapping very steady, transportation when pile.For applicable paper bag can filling quality heavier and profile very irregular band rhombus material, guarantee that again the bag body of paper bag and bottom are can bale broken at this material of can, and can be well moistureproof when storing material after filled material.

The utility model content

The technical problems to be solved in the utility model is inadequate in order to overcome prior art paper bag tensile strength, stores the easy bale broken of profile fitfull material, and the material defective of easily making moist, and a kind of paper bag is provided.

The utility model is to solve above-mentioned technical matters by following technical proposals: a kind of paper bag, it comprises a body, described body is enclosed by a bottom surface and a side and forms, its characteristics are, described side comprises two-layer at least paper and one deck inner membrance from outside to inside successively, the local adhesion successively of described paper and described inner membrance; Described bottom surface covers the lower end of described side, and makes with described side by an easy bracing wire and be connected.

Preferably, the material of described inner membrance is polyethylene.The PE(polyethylene); full Polyethylene by name; it is the simplest macromolecular organic compound of structure; the most widely used High molecular material in the world today; the PE protective film is take Special polyethylene (PE) plastic sheeting as base material, is divided into high density polyethylene (HDPE) protective film, medium density polyethylene and Low Density Polyethylene according to the difference of density.

The PE(polyethylene) advantage of protective film maximum is that protected product is not contaminated in production and processing, transportation, storage and use procedure, burn into scratches, and protects original bright and clean glossy surface, thereby improves quality and the market competitiveness of product.

Preferably, described paper comprises one first paper and one second paper.Can further increase the intensity of described paper bag side by two layers of paper, make described paper bag be difficult for broken.

Preferably, described paper and described inner membrance enclose respectively and close up and adhesion, and described paper and described the inner membrance position of adhesion respectively stagger mutually.

Preferably, described paper and described inner membrance respectively the position of adhesion be notch cuttype.Such setting can so that described paper bag is produced conveniently, when having avoided the alignment of adhesion section, need the staggered folded complex operations of establishing of bonding end of the described paper that will close up.

Preferably, described bottom surface is straight shape.

Positive progressive effect of the present utility model is: by utilization of the present utility model, overcome in prior art the paper bag bottom can filling quality heavier and profile very irregular band rhombus material, bag body and the bottom that guarantees again paper bag can bale broken when this material of can, and can be well moistureproof when storing material after filled material.

Description of drawings

Fig. 1 is the paper bag block diagram of the utility model preferred embodiment.

Fig. 2 is that the paper bag side of the utility model preferred embodiment forms schematic diagram.

Fig. 3 is the paper of paper bag of the utility model preferred embodiment and the adhesion schematic diagram of inner membrance.

The specific embodiment

The below enumerates preferred embodiment, and comes by reference to the accompanying drawings the clearer the utility model that intactly illustrates.

As Fig. 1 and a paper bag shown in Figure 2, it comprises a body, described body is enclosed by a bottom surface 26 and a side 1 and forms, side 1 comprises layer of polyethylene film 11, one first paper 12 and one second paper 13 from the inside to the outside successively, the upper end of described body is an opening, be used for holding material, the lower end of described body is enclosed with bottom surface 26.Bottom surface 26 is stitched together by easy bracing wire 25 and side 1.The structure that the bottom is sewed up has increased the intensity of paper bag bottom load-carrying, and the bottom can bale broken during heavier and profile fitfull rhombus material in filling quality.In the present embodiment, easily the method for sewing of bracing wire 25 is those skilled in the art's common technology means, and and therefore not to repeat here.

As shown in Figure 3, polyethylene film 11, the first paper 12 and the second paper 13 enclose respectively and close up and adhesion, and the position of adhesion is respectively in interior film coalescence section 21, the first paper adhesion section 22 and the second paper adhesion 23(figure of section and can not find).Interior film coalescence section 21, the first paper adhesion section 22 and the second paper adhesion section 23 are arranged in respectively stepped that as shown in Figure 3 head and the tail stagger after adhesion, again with described stepped adhesion, be after polyethylene film 11, the first paper 12 and the second paper 13 are distinguished adhesions, apply glue on its position of adhesion forms respectively stepped, with polyethylene film 11, the first paper 12 and the second paper 13 adhesion successively.Such setting can so that described paper bag is produced conveniently, when having avoided the alignment of adhesion section, need the staggered folded complex operations of establishing of bonding end of the described paper that will close up.

In addition, polyethylene film 11 passes through it in the outside in a week of described opening part and all adhesions in inboard one of the first paper 12, the inboard adhesion in bottom surface that the outside, bottom surface and the first paper 12 that polyethylene film 11 is folded into is folded into, such compound paper bag has just had good anti-soak properties when storing material.

Although more than described the specific embodiment of the present utility model, it will be understood by those of skill in the art that these are only casehistorys, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make various changes or modifications to these embodiments under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
