A double-layer functional food packaging bag

Abstract

The invention discloses a double-layer functional form food packaging bag and belongs to the field of food packaging. The double-layer functional form food packaging bag comprises a packaging bag bodyof which the upper end is fixedly connected with a packaging bag head through a sealing strip; the packaging bag body comprises an outer packaging bag layer and an inner packaging bag layer; the sealing strip comprises a sealing concave strip and a sealing convex strip; a closed auxiliary drying mechanism is arranged in the position of the sealing concave strip; the lower end of the closed auxiliary drying mechanism is connected with a double-layer drying structure; a plurality of cavities are arranged inside the sealing concave strip; an auxiliary drying combined ball is placed inside the cavity; another closed auxiliary drying mechanism is arranged at the sealing part of the packaging bag body, a double layer drying structure is also arranged in the position of the closed auxiliary drying mechanism, the closing state of the closed auxiliary drying mechanism can be kept under a state that the bag body is opened, so as to keep the stable drying performance of the auxiliary drying combined ball inside the cavity. Therefore, during the food packaging bag re-sealing process, a complete drying effect is played, and the drying effect lasts for long.

Description

Technical field[0001]The invention relates to the field of food packaging bags, and more specifically, to a double-layer functional food packaging bag.Background technique[0002]Most of the existing food packaging bags are open. After opening, if the food is not eaten, external dust and bacteria will easily enter the food in the pocket, and the existing food packaging bags cannot be reused once they are sealed. , Not only a waste of resources, but also not conducive to environmental protection. Most of the existing food packaging bags are plastic bags, and the plastic is in direct contact with the food. When the food is eaten by the consumer, it will have an adverse effect on human health.[0003]At present, vacuum packaging bags have been widely used for packaging various foods that need to be kept fresh, and their main purpose is to reduce food spoilage and oxidative deterioration. Place the food in a vacuum packaging bag, and then evacuate and seal the vacuum packaging bag to preven...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned vacuum packaging bags and most food packaging bags in the prior art can effectively seal food, and the outer bag body can be inflated to protect the inner bag body, once the packaging bag is opened, the effect of resealing is difficult to obtain. Guarantee, after opening, a large amount of oxygen and moisture will enter the packaging bag. Although the general food packaging bag is equipped with a drying bag, when the packaging bag is left open for a long time or frequently, the drying bag will be consumed quickly and its drying effect will be reduced. Reduced, it is difficult to play an effective drying role when the bag is resealed
