Description
Technical Field
The present application relates to a paper bag, and more particularly, to a paper bag which is firm in use.
Background
The paper bag plays a role in packaging and decoration, and can be called as a paper bag as long as the paper bag contains a part of paper products; however, most of the existing paper bags are not tear-resistant, are easy to damage after being wetted, and cannot play a packaging role.
Disclosure of Invention
Aiming at the defects existing in the prior art, the application aims to provide the paper bag which is firm in use and has the beneficial effects of firm use, water resistance and tear resistance.
In order to achieve the above purpose, the present application provides the following technical solutions: the utility model provides a use firm container bag, includes the bag body that comprises bag body paper, its characterized in that: the bag body paper comprises a basal layer; one side of the basal layer is provided with a first paper layer, and the other side of the basal layer is provided with a second paper layer; the side surface of the first paper layer, which is away from the basal layer, is provided with a first waterproof coating; the side surface of the second paper layer, which is away from the basal layer, is provided with a second waterproof coating; a light-proof coating is arranged outside the second waterproof coating; the first waterproof coating is arranged in the bag body.
Through above-mentioned structure setting, the stratum basale is the bio-cotton layer, for cotton fiber's layer structure, has the effect of tearing resistant, and bio-cotton layer and paper layer can conveniently degrade, have environmental protection effect, the setting of waterproof layer can play the waterproof effect, avoids after the wet water, the condition emergence of damaging easily.
The application is further provided with: the basal layer is a biological cotton layer; the thickness of the second paper layer is larger than that of the first paper layer; the first waterproof coating and the second waterproof coating are of a film structure formed by coating waterproof coating.
The application is further provided with: the light-proof coating is a film structure formed by coating black paint or reflective paint.
Through the arrangement of the structure, the light-proof coating can play a role in preventing light aging.
The application is further provided with: the thickness of the basal layer is 0.3-0.4mm; the thickness of the first paper layer is 0.1-0.3mm; the thickness of the second paper layer is 0.2-0.4mm.
Drawings
FIG. 1 is a schematic view of the structure of a bag according to the present embodiment;
fig. 2 is a schematic diagram of the paper layer structure of the bag body in this embodiment.
Reference numerals: 1. a bag body; 2. a base layer; 3. a first paper layer; 4. a second paper layer; 5. a first water-resistant coating; 6. a second waterproof coating; 7. a light-proof coating.
Detailed Description
The present application will be described in further detail with reference to the accompanying drawings.
The embodiment discloses a paper bag which is firm in use, as shown in fig. 1-2, and has the beneficial effects of firm use, water resistance and tear resistance. Comprises a bag body 1 formed by bag body paper, wherein the bag body paper comprises a basal layer 2; a first paper layer 3 is arranged on one side of the substrate layer 2, and a second paper layer 4 is arranged on the other side of the substrate layer; the side of the first paper layer 3 facing away from the substrate layer 2 is provided with a first waterproof coating 5; the side of the second paper layer 4 facing away from the substrate layer 2 is provided with a second waterproof coating 6; a light-proof coating 7 is arranged outside the second waterproof coating 6; the first waterproof coating 5 is arranged in the bag body 1.
Through the above-mentioned structure setting, stratum basale 2 is the bio-cotton layer, for cotton fiber's layer structure, has the effect of tearing resistant, and bio-cotton layer and paper layer can conveniently degrade, have environmental protection effect, the setting of waterproof layer can play the waterproof effect, avoids after the wet water, the condition emergence of damaging easily.
The basal layer 2 is a biological cotton layer; the thickness of the second paper layer 4 is larger than that of the first paper layer 3; the first waterproof coating 5 and the second waterproof coating 6 are film structures formed by waterproof coating.
The light-proof coating 7 is a film structure formed by coating black paint or reflective paint.
By the above arrangement, the light-proof coating 7 can be provided to prevent photoaging.
The thickness of the basal layer 2 is 0.3-0.4mm; the thickness of the first paper layer 3 is 0.1-0.3mm; the thickness of the second paper layer 4 is 0.2-0.4mm.
The above embodiments are only preferred embodiments of the present application, and are not intended to limit the present application, and any modifications, equivalent substitutions, improvements, etc. within the design concept of the present application should be included in the scope of the present application.
