[0002] Packaging is the general name for containers, materials, auxiliaries, etc. used in a certain technical method to protect products during the circulation process, facilitate storage and transportation, and promote sales. A packaging bag refers to a bag used for packaging various articles, making it convenient to transport and store goods during the production and circulation process. Packaging bags are divided into plastic woven bags, plastic film bags, and composite packaging bags. Takeaway bags are an indispensable type of packaging bag in daily life;

[0003] Most of the takeaway bags used by existing merchants are plastic bags made of plastic. Plastic generates a large amount of waste gas and wastewater during production, is highly toxic to organisms, and has a very slow degradation rate of decades or even hundreds of years after becoming garbage, which is not conducive to degradation and environmental protection. In order to practice the concept of environmental protection, some merchants have started to use paper takeaway bags. However, many paper takeaway bags often open by themselves during transportation due to loose packaging, and traditional paper packaging bags cannot maintain the temperature of food within about 30 minutes of delivery time, which will affect the taste of the food. Content of the Utility Model

[0004] In view of the technical defects in the background art, the utility model provides a plastic-free paper-made environmental protection takeaway bag, which solves the above technical problems and meets the actual needs. The specific technical solutions are as follows:

[0005] A plastic-free paper-made environmental protection takeaway bag includes a bag body. The bag body is surrounded by plastic-free cardboard and has one end closed to form a cavity with an upward opening. An inner bag mouth and an outer bag mouth are provided at the opening position of the bag body near the cavity. A handle part is provided at the upper edge of the outer bag mouth, and a winding and sealing structure is provided at the upper edge of the inner bag mouth. The cavity is divided into a first cavity and a second cavity up and down along the intersection position of the inner bag mouth and the outer bag mouth. A heat-insulating layer is provided at the position of the bag body corresponding to the second cavity.

[0006] As an improvement of the above solution, the plastic-free cardboard includes an inner layer cardboard and an outer layer cardboard arranged from the inner side to the outer side of the bag body. A sandwich cardboard is clamped between the inner layer cardboard and the outer layer cardboard corresponding to the opening position of the bag body.

[0007] As an improvement of the above solution, the sandwich cardboard is clamped in a V shape between the inner layer cardboard and the outer layer cardboard, thereby separating the inner layer cardboard and the outer layer cardboard. The inner layer cardboard and the sandwich cardboard are compounded to form the inner bag mouth, and the outer layer cardboard and the sandwich cardboard are compounded to form the outer bag mouth.

[0008] As an improvement on the above scheme, an insulation layer is sandwiched between the inner cardboard and the outer cardboard at positions corresponding to the second cavity, and the insulation layer is formed by bending a single cardboard into a wave shape, wherein the insulation layer and the inner and outer cardboards are fixed by a degradable adhesive.

[0009] As an improvement of the above-mentioned scheme, the winding sealing structure includes a winding cardboard arranged along the width direction of the inner bag opening and an annular iron wire passing through the middle of the winding cardboard, the length dimension of the winding cardboard is the same as the width dimension of the inner bag opening, and the end of the annular iron wire extends outward along the end of the winding cardboard.

[0010] As an improvement of the above solution, the winding sealing structure includes an adhesive area arranged on the inner side of the inner bag opening and extending along the width direction of the inner bag opening, and a release layer compounded on the surface of the adhesive area.

[0011] As an improvement of the above-mentioned scheme, the cross-section of the plastic-substitute cardboard is Y-shaped, the inner cardboard and the outer cardboard are an integrated structure, the vertical extension height of the inner cardboard is lower than the vertical extension height of the outer cardboard, and the bottom end of the inner cardboard and the bottom end of the outer cardboard meet at the middle position of the height direction of the bag body.

[0012] The utility model has the beneficial effects that: the bag body has a higher proportion of degradable materials. Compared with plastic bags, paper bags are easy to degrade naturally after use and discarded, and the degradation time is also faster. The lower half of the bag body is sandwiched with a heat preservation layer, so that the bag body has a higher structural strength and a heat preservation function. The inner bag mouth seals the second cavity through a winding sealing structure to reduce heat loss during transportation, and at the same time divides the cavity into a first cavity and a second cavity distributed up and down. Other foods or drinks that are not suitable for hot food to be placed in the same cavity can be placed in the first cavity to avoid affecting the taste of the food. After the bag body is divided, it can achieve a better preservation effect. BRIEF DESCRIPTION OF THE DRAWINGS
