Abstract
The utility model discloses a composite paper bag, which comprises an intermediate layer, an inner surface layer and an outer surface layer. The intermediate layer is formed by adhering two kraft paper layers via interval coating glue, the inner surface layer is adhered to one face of the intermediate layer via interval coating glue, and the outer surface is adhered to the other face of the intermediate layer via interval coating glue. The composite paper bag has the advantages of environment protection and difficult cracking.
Description
Technical field
The utility model relates to a kind of compound paper bag and production method thereof, is applicable to the packaging for foodstuff field.
Background technology
Existing compound paper bag, as shown in Figure 1, its combination board comprises interlayer 2 and inner and outer surface layers 1,3, interlayer 2 is bonded by evenly being coated with full glue 5 therebetween for two- layer craft paper 21,22, inner and outer surface layers 1,3 is degradable polyethylene PE, uppermost layer 3 can be done printing treatment as required, and uppermost layer 3 is by evenly being coated with the wherein one side that full glue 5 fits in interlayer 2, and endosexine 1 is also by evenly being coated with the another side that full glue 5 fits in interlayer 2.
Though this kind compound paper bag good waterproof performance is widely used in various packagings for foodstuff, because of its combination board glue consumption is many, fragility is arranged, make manufactured product environmental protection easy to crack and not enough.
In view of the shortcomings and deficiencies that above-mentioned compound paper bag exists, the inventor develops a kind of colory compound paper bag.
The utility model content
The purpose of this utility model is to provide a kind of compound paper bag, and it has environmental protection and fine quality not easy to crack.
To achieve these goals, the technical solution of the utility model is:
A kind of compound paper bag, its combination board comprises interlayer and inner and outer surface layers, wherein, interlayer is that two-layer craft paper is bonded by the glue that is coated with at interval, the glue that the endosexine is coated with by the interval fits in the wherein one side of interlayer, and uppermost layer fits in the another side of interlayer by the glue of even coating.
Keeping parallelism between the glue of described interval coating, and the ratio of the glue width of coating at interval and gap width is 1: 2.
Adopt said structure, combination board of the present utility model is by between craft paper, and the interval is coated with glue between craft paper and the endosexine, and its glue consumption is few, and has shock-resistance features, environmental protection and not easy to crack when its manufactured product compound paper bag is applied to packaging for foodstuff.
Description of drawings
Fig. 1 is the combination board structural representation of existing compound paper bag;
Fig. 2 is a combination board structural representation of the present utility model.
Label declaration:
Interlayer 2 craft papers 21,22
Uppermost layer 3
The specific embodiment
Figure 2 shows that combination board structural representation of the present utility model, a kind of compound paper bag, its combination board comprises interlayer 2 and inner and outer surface layers 1,3, wherein, interlayer 2 is bonded for the glue 4 of two- layer craft paper 21,22 by coating at interval, inner and outer surface layers 1,3 is degradable polyethylene PE, and the glue 4 that endosexine 1 is coated with by the interval fits in the wherein one side of interlayer 2, and uppermost layer 3 fits in the another side of interlayer 2 by the glue 5 of even coating.
In the present embodiment, keeping parallelism between the glue 4 of coating, and the glue 4 width a of coating at interval at interval and the ratio of gap width b are 1: 2, and certainly, glue 4 also can be the interval coating of other form, and the ratio of a and b is not limit by this yet.
Combination board of the present utility model is because of being coated with glue 4 at interval between the two- layer craft paper 21,22 and between craft paper 22 and the endosexine 1, and glue 4 consumptions are few, the compound paper bag environmental protection that makes, not easy to crack.
Above-mentioned only is preferred embodiment of the present utility model, and glue 4 distributional patterns of coating and the ratio of width a and gap width b thereof are not limit by this all at interval, and all modification conversion of doing according to key points in design of the present utility model all fall into protection domain of the present utility model.
Claims (2)
1. compound paper bag, its combination board comprises interlayer and inner and outer surface layers, it is characterized in that: described interlayer is that two-layer craft paper is bonded by the glue that is coated with at interval, the glue that the endosexine is coated with by the interval fits in the wherein one side of interlayer, and uppermost layer fits in the another side of interlayer by the glue of even coating.
2. a kind of compound paper bag as claimed in claim 1 is characterized in that: keeping parallelism between the glue of described interval coating, and the ratio of the glue width of coating at interval and gap width is 1: 2.
