[0002] Food paper bags are a kind of container made of paper or paper composite materials. There are many kinds of paper bags, which can be divided into paper bags, coated paper bags, and waxed paper bags according to the materials. In order to facilitate the taking of food, convenience stores, snack stalls, etc. will directly place the heated food in food packaging paper bags (referred to as food paper bags). Since the temperature of the food is high and the heat insulation of the food packaging paper bags is poor, consumers are prone to burn their hands when they take the food directly; at the same time, when the food placed is some fried food, when consumers hold the paper bags containing fried food, oil stains are easy to penetrate the paper bags, so that a layer of oil stains will adhere to the hands of consumers. Therefore, the existing technology has the problem of poor heat insulation and oil resistance. Utility Model Content

[0005] In the aforementioned oil-proof and heat-insulating food packaging paper bag, the connecting piece includes a first buckle strap and a female buckle located at the bottom of one of the flexible insulation pads, and also includes a second buckle strap and a male buckle located at the bottom of the other flexible insulation pad.

[0006] In the aforementioned oil-proof and heat-insulating food packaging paper bag, the outer wall surface of the flexible heat-insulating pad is also provided with one or more paper finger ring buckles.

[0007] In the aforementioned oil-proof and heat-insulating food packaging paper bag, the flexible heat-insulating pad comprises two layers of reinforcing paper distributed inside and outside, and heat-insulating cotton is arranged between the two layers of reinforcing paper.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] 1. The paper bag of the present application is composed of an inner layer of a food paper bag, an outer layer of a food paper bag, an oil-proof coating and a polytetrafluoroethylene microporous film arranged between the inner and outer layers, and an oil-proof edible wax layer arranged on the inner side of the inner layer of the food paper bag, thereby effectively improving the overall anti-oil seepage performance; moreover, the overall thickness of the paper bag is increased, and the heat insulation performance can also be improved to a certain extent;

[0010] 2. The utility model can greatly improve the thermal insulation performance of the food paper bag by arranging flexible thermal insulation pads at the two long sides of the outer layer of the food paper bag, making it easier for consumers to take the food paper bag. At the same time, the top of the flexible thermal insulation pad is fixedly connected to the outer layer of the food paper bag, and the lower ends of the two flexible thermal insulation pads are detachably connected by a connecting piece, so that it can be used as an thermal insulation pad and also as a hand rope, making the taking method flexible and changeable.

[0011] In summary, the utility model has the characteristics of being able to effectively improve the heat insulation performance and oil resistance performance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0018] Embodiment. An oil-proof and heat-insulating food packaging paper bag, comprising: Figure 1-4As shown, it includes an inner layer 1 of a food paper bag and an outer layer 2 of a food paper bag, between which an oil-proof coating 3 and a polytetrafluoroethylene microporous film layer 4 are provided; the inner side of the inner layer 1 of the food paper bag is provided with an oil-proof edible wax layer 5; and it also includes two flexible thermal insulation pads 6 located outside the two long side ends of the outer layer 2 of the food paper bag, the upper end of the flexible thermal insulation pad 6 is fixed to the top of the outer layer 2 of the food paper bag, and the bottom ends of the two flexible thermal insulation pads 6 are detachably connected via a connecting piece 7.
