DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with Figures 1-5 and embodiments.

[0027] Embodiment 1: As shown in FIGS. 1-5 , a portable flame retardant and moisture-proof food packaging bag comprises a bag body 1, a moisture-proof bag 2, a portable board 3 and a support board 4. The bag body 1 has a storage cavity 5 inside. The bag body 1 comprises an easy-tear portion and a moisture-proof and flame retardant portion at the upper part of the bag body 1. The moisture-proof and flame retardant portion of the bag body 1 comprises an outer bag surface layer 6, a waterproof layer 7, a flame retardant layer 8 and an inner bag surface layer 9 which are sequentially glued together from the outside to the inside, as shown in FIG. Figure 4 As shown, the outer bag surface layer 6 is made of kraft paper, and the inner bag surface layer 9 is made of PP plastic film. The high tearing strength of kraft paper can improve the strength of the bag body 1. PP plastic is safe and non-toxic and is suitable for use as the inner bag surface and food contact. The waterproof layer 7 is made of PE waterproof film, and the flame retardant layer 8 is made of soft porcelain material. The PE waterproof film and the soft porcelain material are used to improve the moisture-proof and flame-retardant properties of the bag body 1. The bag body 1 is provided with the waterproof layer 7 and the flame retardant layer 8, which improves the moisture-proof and flame-retardant properties of the bag body 1. The easy-to-tear portion does not include the waterproof layer 7 and the flame retardant layer 8, so it will not affect the tearing of the easy-to-tear portion.

[0028] As shown in FIG1 , the tearable portion of the bag body 1 includes an outer bag surface layer 6 and an inner bag surface layer 9 which are adhesively connected to each other. The upper two side surfaces of the bag body 1 are adhered to each other to form a seal for the storage cavity 5. Tearable notches 20 are provided on both sides of the tearable portion. The tearable notches 20 are used to tear open the upper portion of the bag body 1. The tearable notches 20 make it easier and more convenient to tear open the upper portion of the bag body 1. When the upper portion of the bag body 1 is torn open, as shown in FIG2 , an access port 10 is formed at the upper end of the remaining portion of the bag body 1, so that the storage cavity 5 is exposed to the outside. A sealing strip 11 is provided on the upper portion of the moisture-proof and flame-retardant portion of the bag body 1. The sealing strip 11 has two inner side surfaces respectively fixedly connected to the opposite sides of the bag body 1. The sealing strip 11 is used to reseal the storage cavity 5 after the bag body 1 is opened. The sealing strip 11 allows the packaging bag to be resealed after it is opened, thereby avoiding waste and increasing the shelf life of the food, and allowing the food packaging bag to be reused.

[0029] As shown in FIG3 , the moisture-proof bag 2 is fixedly connected to the inner side surface of the upper part of the storage cavity 5, one side of the moisture-proof bag 2 is shared with the inner bag surface layer 9, the moisture-proof bag 2 is opened upward for placing the desiccant, the moisture-proof bag 2 includes a breathable surface 13 away from the side of the connected bag body 1, the breathable surface 13 is provided with evenly arranged breathable holes 14, and the upper part of the breathable surface 13 is provided with an easy-to-take notch 15, and the easy-to-take notch 15 is used to take the desiccant in the moisture-proof bag 2. The breathable holes 14 can increase the contact area between the desiccant and the air, thereby improving the absorption efficiency of the desiccant, and the desiccant can be taken out more easily through the easy-to-take notch 15. This food packaging bag is also provided with a moisture-proof bag 2 for placing a moisture-proof agent, which can place the moisture-proof agent separately, so that the food and the moisture-proof agent are effectively distinguished, and it is also more convenient to take and replace the moisture-proof agent.

[0030] like Figure 1As shown, the hand plate 3 has two outer sides fixedly connected to the upper part of the bag body 1, and the two hand plates 3 are provided with a pull-out opening 12, which corresponds to each other and is higher than the upper end of the bag body 1. The bag body 1 can be carried by hand through the pull-out opening 12. The upper ends of the two pull-out openings 12 are provided with a wavy extraction notch 16, which can increase the contact area between the finger and the hand plate 3, thereby reducing the pressure and making it more comfortable to extract. The tearable part on the upper part of the bag body 1 and the two hand plates 3 are provided with corresponding "convex"-shaped hanging openings 17, which can be hung on the shelf when sold through the hanging openings 17. This food packaging bag is provided with a hand plate 3, and the pull-out opening 12 provided on the hand plate 3 makes it more convenient for users to carry this food packaging bag.

[0031] As shown in Figures 1 and 5, the support plate 4 is fixedly connected to the lower end surface of the bag body 1, and the size of the support plate 4 corresponds to the size of the lower end surface of the bag body 1. The bag body 1 also includes two side walls, and the two side walls are perpendicular to the sealing strip 11. The two side walls are provided with a first easy folding line 18, and the first easy folding line 18 is used to fold the bag body 1 to reduce the volume for easy transportation. A second easy folding line 19 is provided in the middle of the support plate 4, and the second easy folding line 19 is parallel to the length direction of the sealing strip 11. When the bag body 1 is folded through the first easy folding line 18, the support plate 4 can be flipped inward and folded through the second easy folding line 19. The material of the support plate 4 is cardboard. When the packaging bag is transported, the bag body 1 can be folded by the first easy folding line 18 and the second easy folding line 19 to reduce the required space and increase the transportation quantity. When food is put into the bag body 1, the bag body 1 will be pressed down to make the support plate 4 flip outward and flatten. The support plate 4 makes it difficult for the bag body 1 to tilt when placed and the bottom is not easy to be scratched to adapt to more different usage scenarios. The support plate 4 makes this food packaging bag adapt to more different usage scenarios, and improves the strength of the bottom of the packaging bag so that it is not easy to be damaged, and is more convenient to place.

[0032] It is worth noting that the sealing strip features involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated.

[0033] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made by technicians in the relevant technical field based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
