Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, and in particular relates to a double-sealed food packaging bag. Background Technology

[0002] Food packaging is the process of sealing food using packaging bags or boxes. Packaging bags can be classified into plastic packaging bags, paper packaging bags, and aluminum foil packaging bags according to their materials. Food packaging bags mainly consist of two parts: the packaging bag body and the sealing component. The sealing component can be further divided into two categories: sealing strip structure and heat sealing structure.

[0003] Chinese patent application CN223149168U discloses a highly airtight food packaging bag with a double-sealing structure, including a bag body. A bottom plate is fixedly connected to the bottom of the bag body. Two limiting grooves are formed inside the bottom plate, extending to the outside. Each limiting groove has a slidably connected limiting frame inside. A pressure plate is fixedly connected between the two limiting frames. A power groove with a U-shaped cross-section is formed inside the bottom plate. A fixed frame with an L-shape is slidably connected inside the power groove. This highly airtight food packaging bag with a double-sealing structure uses the force of a spring to cause the fixed frame to slide into the fixed groove, thus fixing the positions of the limiting frame and the pressure plate, thereby fixing the position of the bag body and enabling folding of the bag body for easier storage.

[0004] The aforementioned high-sealing food packaging bag with a double-sealing structure has components such as the bag bottom plate, pressure plate, drawstring, and rotating shaft. The cost of these components far exceeds the price of the bag itself, leading to excessively high production costs. Furthermore, the bag body comprises a corrosion-resistant layer, PET film, a base layer, and BOPP film. This multi-layered film structure increases the bag's wall thickness, reducing the amount of food that can be stored. Therefore, we provide a double-sealing food packaging bag to address these problems. Utility Model Content

[0005] The purpose of this invention is to provide a double-sealed food packaging bag. The inner bag can be used to package food, and the outer bag can be used to store the inner bag. The inner bag is fixed to a designated position on the outer bag by an adhesive component. The outer bag is made of polyethylene, and the inner bag is made of paper base and polyester functional film material. This improves the safety of the packaged food and reduces the thickness of the packaging bag, thus solving the problems of the aforementioned high-sealing food packaging bag with a double-sealing structure.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a double-sealed food packaging bag, including an outer bag body; an inner bag body is provided inside the outer bag body, a sealing strip is provided on the upper open end of the outer bag body, a sealing strip is provided on the upper open end of the inner bag body, and an adhesive component is provided on the upper side wall of the inner bag body. The adhesive component includes an adhesive strip first attached to the outer wall of the inner bag body and an adhesive strip second attached to the inner wall of the outer bag body. The outer bag has a packaging groove inside, and storage grooves are provided in the front and rear side walls of the packaging groove. An adhesive groove is provided at the upper end of the storage groove. The storage grooves are provided one-to-one with the inner bag. The second adhesive strip is adhered to the adhesive groove and is adhered to the first adhesive strip. The inner bag consists of a paper base and a polyester functional film, while the outer bag is made of polyethylene material.

[0007] The present invention is further configured such that the polyester functional film covers one side of the paper base layer, the polyester functional film side of the inner bag body is used to contact the food, and the paper base layer side is used to contact the inner wall of the outer bag.

[0008] The present invention is further configured such that the storage slots are provided in two sets, and each set of the storage slots is provided with three slots, and the three storage slots are equally spaced.

[0009] This utility model has the following beneficial effects: 1. This utility model, by setting an outer bag body, an inner bag body, and an adhesive component, includes an inner bag body inside the outer bag body. An adhesive component is set on the side wall of the end of the inner bag body. The adhesive component includes an adhesive strip two that is pasted on the inner wall of the outer bag body and an adhesive strip one that is pasted on the outer wall of the inner bag body. The adhesive strip one and adhesive strip two are also bonded to each other. Multiple inner bags are set, and the multiple inner bags are divided into two groups. The two groups of inner bags are respectively set opposite to each other on the front and back sides of the outer bag body. This not only achieves independent packaging, but also provides sealing strip one and sealing strip two on the opening ends of the outer bag body and the inner bag body, respectively, to achieve the effect of quick sealing of the outer bag body and the inner bag body. The double sealing packaging maximizes the safety of food. At the same time, the independent packaging structure makes it more convenient to eat. If the food is not finished after packaging, it can still be resealed. The adhesive component also ensures that the inner bag body can be placed back on the designated position on the outer bag body, avoiding mutual collision between the inner bags and reducing the degree of damage to the food inside the inner bag.

[0010] 2. This utility model uses a paper base layer and a polyester functional film. The outer bag is made of polyethylene material, while the inner bag is made of a paper base layer and a polyester functional film. The polyester functional film is located on the outside of the paper base layer, and one side of the polyester functional film is used to directly contact the food, while the paper base layer is used to contact the outer bag. This maximizes the safety of the food in the inner bag and also reduces the thickness of the packaging bag. Attached Figure Description
