Technical Field

[0001] This utility model relates to the field of kraft paper bags, and in particular to a portable and environmentally friendly kraft paper bag. Background Technology

[0002] Kraft paper bags are durable paper bags made of kraft paper, widely used in packaging, shopping, and various logistics applications. Kraft paper, also known as kraft pulp paper, is named for its strong properties and natural brown appearance.

[0003] Existing kraft paper bags lack proper bottle containment design, causing water bottles to easily move around inside and leak, contaminating other items such as electronics and clothing. Furthermore, the bottom of the bags is prone to damage with prolonged use. These issues not only negatively impact user experience but also negatively affect environmental performance. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a portable and environmentally friendly kraft paper bag. By setting a bottle limiting bag and using an elastic shrink band, the water bottle is limited inside the kraft paper bag. The life of the kraft paper bag is enhanced by setting a plastic gasket.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A portable, environmentally friendly kraft paper bag, comprising a kraft paper bag body;

[0007] The upper surface of the kraft paper bag body is integrally provided with paper bag handles on both sides;

[0008] Side reinforcing strips are attached to both sides of the exterior of the kraft paper bag body;

[0009] The kraft paper bag body has an internal cavity, and a bottle limiting bag is installed on one inner wall of the kraft paper bag body. The bottle limiting bag is semi-circular and has an accommodating cavity.

[0010] Two connecting buckles are provided on one inner wall of the kraft paper bag body, and an elastic shrink band is connected between the two connecting buckles. The elastic shrink band is made of elastic fabric sewn together.

[0011] The bottom of the kraft paper bag body is provided with a waterproof plastic sheet, and two adhesive tapes are attached to the bottom of the waterproof plastic sheet. A plastic reinforcing pad is attached to the bottom of the two adhesive tapes together.

[0012] The inner wall of the kraft paper bag is coated with a waterproof layer.

[0013] The outer wall of the kraft paper bag is coated with a wear-resistant layer.

[0014] Furthermore, the plastic reinforcing pad is rectangular and completely covers the bottom area of ​​the kraft paper bag body.

[0015] Furthermore, the waterproof layer is a chlorinated polyethylene waterproof coating.

[0016] Furthermore, the wear-resistant layer is made of polytetrafluoroethylene film.

[0017] Furthermore, the water bottle body is movably placed inside the bottle body limiting bag, and the elastic contraction band is semi-circular and surrounds the water bottle body.

[0018] Furthermore, the side reinforcing sheet has several ventilation holes on its side, and the ventilation holes penetrate the side reinforcing sheet and the kraft paper bag body. The diameter of the ventilation holes is less than 0.5 mm and the distance between adjacent ventilation holes is less than 5 mm.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By setting a waterproof plastic sheet at the bottom of the kraft paper bag body and setting adhesive tape at the bottom of the waterproof plastic sheet, the adhesive tape can be used to attach the plastic reinforcing pad to the bottom surface of the kraft paper bag body, thereby improving the stability and durability of the kraft paper bag body on wet or uneven surfaces, and enhancing the structural strength and waterproof performance of the bottom of the kraft paper bag body.

[0021] 2. By setting a bottle-limiting bag and a connecting buckle on the inner wall of the kraft paper bag, and by installing an elastic shrink band through the connecting buckle, the bottle-limiting bag can work with the elastic shrink band to limit and fix the water bottle placed inside the bottle-limiting bag, thereby effectively preventing the water bottle from shaking or tipping over inside the bag, and improving the portability and stability of the kraft paper bag.

[0022] 3. By applying a waterproof layer to the inner wall of the kraft paper bag and a wear-resistant layer to the outer wall, the waterproof and wear-resistant layers can significantly improve the waterproof and wear-resistant performance of the kraft paper bag, enhance its stability and durability, prevent the contents from getting damp and damaged, extend the service life of the kraft paper bag, and improve the environmentally friendly reusability of the kraft paper bag.
