The convenient food packaging bag provided by the utility model is convenient for eating and storing food, avoids waste and protects the environmental sanitation. This technical scheme has designed 3 seals and 3 lugs to the sealing part to solve the sealed problem of wrapping bag.

In fact, to solve the technical problem of food packaging for different technical problems, the actual working purpose, working environment and the conditions to be met for the purpose need to be specifically considered.

Aiming at the technical field of food packaging, the method is an objective requirement in consideration of meeting the packaging requirement and solving the environmental protection problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a structure of a full-biodegradable food packaging bag, and the food packaging bag can be quickly biodegraded through composting treatment after being used by adopting a biodegradable film to replace the traditional polyethylene and polypropylene films, so that the emission of carbon dioxide is effectively reduced, and the development requirement of green and low carbon is met.

The purpose is achieved, and the experiment is novel in that the following technical scheme is adopted:

the utility model provides a structure of full biodegradable food package bag, food package bag includes folded cascade upper end opening, the closed cuboid in bottom, and the wrapping bag openly is provided with visual window.

Further, according to the technical requirements in the art, the specific dimensions of the rectangular parallelepiped-shaped packaging bag of the present invention are as follows: the length was 115mm, the width was 70mm and the height was 245 mm. The size design takes food packaging requirements and physical characteristics of the materials used into consideration, and is more beneficial to processing and use.

Further, the specific size of the visual window on the front side of the packaging bag is as follows: the length is 80mm and the height is 100 mm.

Furthermore, the main body of the packaging bag is formed by compounding kraft paper and a biodegradable transparent film, the kraft paper is arranged on the outer side of the packaging bag, and the biodegradable film is arranged on the inner side of the packaging bag.
