[0025] As shown in Figures 1-4 The utility model provides a kind of environment-friendly food sealing packaging bag, comprising: bag body 1, the outer surface of bag body 1 upper end one side is fixedly installed with multiple recessed strip 101, bag body 1 upper end other side is fixedly installed with multiple tab band 104, multiple recessed strip 101 and tab band 104 are symmetrical, further comprising: multiple reinforcing sheets 105, are fixedly installed in the bottom of bag body 1;Bag body 1 upper end center is provided with handle slot 102;Bag body 1 is close to the upper end of both sides and is provided with easy-to-pull mouth 103.

[0026] In the embodiment, the food in the bag body 1 can be taken by tearing the easy-to-pull mouth 103 opened on the two sides of the upper end of the bag body 1. When the bag body 1 needs to be sealed, first, the bag mouth of the bag body 1 is relatively attached after being torn, then the bag mouth is rolled up, the recessed strip 101 on one side of the bag body 1 is attached to the tab band 104 on the other side, and the recessed strip 101 and the tab band 104 are tightly attached together by pressing to form a seal. The number of recessed strips 101 and tab bands 104 can be adjusted according to the amount of food in the bag body 1, which can reduce the air and volume in the bag body 1, and more conveniently store the bag body 1. The bag body 1 is internally fixedly installed with multiple reinforcing sheets 105, which can improve the load-bearing capacity of the bottom of the bag body 1. The upper end of the bag body 1 is provided with a handle slot 102 to facilitate the purchase and taking of the bag body 1.

[0027] As shown in Figures 1-4 The utility model provides a kind of environment-friendly food sealing packaging bag, comprising: bag body 1, the outer surface of bag body 1 upper end one side is fixedly installed with multiple recessed strip 101, bag body 1 upper end other side is fixedly installed with multiple tab band 104, multiple recessed strip 101 and tab band 104 are symmetrical, further comprising: multiple reinforcing sheets 105, are fixedly installed in the bottom of bag body 1;Bag body 1 upper end center is provided with handle slot 102;Bag body 1 is close to the upper end of both sides and is provided with easy-to-pull mouth 103.

[0028] The inside of the bag body 1 is fixedly installed with a U-shaped isolation inner bag 108. The dry sheet or dry bag is put in, so that the dry sheet is separated from the food, preventing accidental ingestion and improving safety. The outer surface of the U-shaped isolation inner bag 108 is provided with a plurality of through holes 109. The through holes 109 can make the dry sheet effectively absorb the moisture in the air in the bag body 1, thereby reducing the humidity and preventing mold growth caused by dampness and other problems. The inside of the bag body 1 is provided with a moisture-proof layer 107. The moisture-proof layer 107 can improve the waterproof and moisture-proof performance of the bag body 1, and better improve the eating taste of the food in the bag body 1.

The outer surface of the moisture-proof layer 107 is provided with an oxygen permeation prevention layer 106. The oxygen permeation prevention layer 106 is made of polylactic acid, which has oxygen barrier performance and can reduce the oxygen permeability of the bag body 1, thereby better improving the shelf life of the food. The bio-based plastic and polylactic acid are both degradable, thereby improving environmental protection.

[0029] Working principle: In use, the food in the bag body 1 can be taken out by tearing the easy-to-pull opening 103 formed on the upper end of the bag body 1. When the bag body 1 needs to be sealed, first, the bag opening of the bag body 1 is relatively attached after being torn, and then the bag opening is rolled up, so that the concave strip belt 101 on one side of the bag body 1 is attached to the convex strip belt 104 on the other side. Pressing makes the concave strip belt 101 and the convex strip belt 104 tightly attached together to form a seal. The plurality of concave strip belts 101 and convex strip belts 104 can be adjusted according to the amount of food in the bag body 1, which can reduce the air and volume in the bag body 1, and more conveniently store the bag body 1. A plurality of reinforcing sheets 105 are fixedly installed in the bag body 1, which can improve the load-bearing capacity of the bottom of the bag body 1. A handle groove 102 is formed on the upper end of the bag body 1, which is convenient for taking the bag body 1 when purchasing. A U-shaped isolation inner bag 108 is fixedly installed on one side of the inside of the bag body 1. The dry sheet or dry bag is put in, so that the dry sheet is separated from the food, preventing accidental ingestion and improving safety. The outer surface of the U-shaped isolation inner bag 108 is provided with a plurality of through holes 109. The through holes 109 can make the dry sheet effectively absorb the moisture in the air in the bag body 1, thereby reducing the humidity and preventing mold growth caused by dampness and other problems. The inside of the bag body 1 is provided with a moisture-proof layer 107. The moisture-proof layer 107 can improve the waterproof and moisture-proof performance of the bag body 1, and better improve the eating taste of the food in the bag body 1. The moisture-proof layer 107 is made of bio-based plastic, which has good barrier performance. The bio-based plastic is made of renewable resources such as corn starch and sugarcane, and has high safety. The outer surface of the moisture-proof layer 107 is provided with an oxygen permeation prevention layer 106. The oxygen permeation prevention layer 106 is made of polylactic acid, which has oxygen barrier performance and can reduce the oxygen permeability of the bag body 1, thereby better improving the shelf life of the food. The bio-based plastic and polylactic acid are both degradable, thereby improving environmental protection.

[0030] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
