Description

Double-layer waterproof kraft paper for packaging bag

Technical Field

The utility model belongs to the technical field of the kraft paper for the wrapping bag, especially, relate to a double-deck waterproof kraft paper for wrapping bag.

Background

Kraft paper, which is mainly used for packaging materials, has a high strength of its own and is generally yellowish brown. Half-bleached or full-bleached kraft pulp is light brown, cream-colored or white, and kraft paper has higher tear strength, rupture strength and dynamic strength than other materials made of wrapping paper, and is generally used as a packaging material. The kraft paper in the market has some problems in use, for example, when the kraft paper is used in the field of medical packaging, the requirements on the waterproofness and the bacteriostatic property of the kraft paper are often higher, and the kraft paper has poor waterproof and bacteriostatic effects and cannot be directly used as a medical packaging bag material. Therefore, design a waterproof effectual double-deck waterproof kraft paper for medical wrapping bag of antibacterial, satisfy medical field's waterproof, antibacterial user demand, it is very important.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model provides a double-layer waterproof kraft paper for packaging bags.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a wrapping bag is with double-deck waterproof kraft paper, includes first kraft paper layer, second kraft paper layer, link together through the adhesive linkage between first kraft paper layer and the second kraft paper layer, first kraft paper layer's upper surface is equipped with first antibacterial layer, the upper surface on first antibacterial layer is equipped with the waterproof layer, second kraft paper layer's lower surface is equipped with the second antibacterial layer.

Further, the bonding layer is inorganic glue or water-based composite glue.

Furthermore, the first antibacterial layer and the second antibacterial layer are both nano antibacterial films.

Further, the thickness of the first antibacterial layer and the second antibacterial layer is 10-30 μm.

Further, the waterproof layer is a film prepared from any one of a PE material, a PP material, a PVC material, a PC material, a PET material or a thermoplastic elastomer.

Compared with the prior art, the beneficial effects of the utility model are that: the double-layer kraft paper has high toughness, so that the integral tear strength can be effectively improved; by arranging the first antibacterial layer and the second antibacterial layer, the internal and external double-layer antibacterial and bacteriostatic effects are achieved, the probability of bacterial breeding at the bottom and on the surface of the kraft paper is effectively reduced, and the antibacterial and bacteriostatic performance of the kraft paper is further improved; the surface waterproof layer is arranged, so that the outer surface of the kraft paper has waterproof and waterproof performances under the conditions of moisture or water, and is firm and durable. The kraft paper has the advantages of simple structure, low processing cost and strong practicability.

Drawings

Fig. 1 is a schematic view of the internal structure of the present invention.

In the figure: 1 a first kraft layer, 2 a second kraft layer, 3 an adhesive layer, 4 a first antibacterial layer, 5 a waterproof layer, 6 a second antibacterial layer.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.
