Description

Technical Field

[0001] This utility model relates to the field of aluminum foil bag technology, specifically a high-barrier food-grade aluminum foil bag. Background Art

[0002] Aluminum foil bags are packaging bags made of aluminum foil and other plastic films. They combine the excellent properties of aluminum foil with the functions of plastic film, and have advantages such as excellent barrier properties, moisture resistance, airtightness, light protection, and non-toxicity and odorlessness. They are widely used in packaging for food, pharmaceuticals, electronic products, chemical raw materials and many other fields.

[0003] During the production of food-grade aluminum foil bags, a sealing strip is usually added inside to keep the food inside sealed even after opening. However, when tearing open the aluminum foil bag, it may be torn crookedly for various reasons. In addition, the tear and sealing strip of most aluminum foil bags are close to each other, which can easily result in the aluminum foil bag above the sealing strip being missing, making it difficult to open the sealing strip. Therefore, there is a need to provide a high-barrier food-grade aluminum foil bag. Utility Model Content

[0004] The purpose of this utility model is to provide a high-barrier food-grade aluminum foil bag to solve the problems mentioned in the background art, such as the possibility of tearing the aluminum foil bag crookedly due to various reasons, and the fact that the tear of most aluminum foil bags is close to the sealing strip, which easily leads to the lack of aluminum foil bag above the sealing strip, thus making it difficult to open the sealing strip. To achieve the above objectives, this utility model provides the following technical solution: a high-barrier food-grade aluminum foil bag, comprising an aluminum foil bag body, a sealing component on the top of the aluminum foil bag body, the sealing component comprising a sealing strip, the sealing strip being fixedly connected to the top of the aluminum foil bag body, the sealing strip having an arc-shaped tear opening on its front side, a flat dotted line on its front side, and a convenient tear opening on its front side. By installing the sealing component, when it is necessary to open the aluminum foil bag body, the aluminum foil bag body can be squeezed first, and then the flat dotted line on the sealing strip can be used to make the cut of the torn sealing strip smoother. The convenient tear opening makes it easier to tear the aluminum foil bag body. At this time, by pulling the arc-shaped tear opening, half of the sealing strip can be torn off, and by pulling the other half of the sealing strip, the aluminum foil bag body can be easily opened, avoiding the situation where the sealing strip is completely torn off, which would make it inconvenient to open the aluminum foil bag body, thus improving the practicality of the device.

[0005] More preferably, a sealing strip is fixedly connected inside the aluminum foil bag body, a sealing groove is provided on one side of the sealing strip, and a sealing block is fixedly connected to the other side of the sealing strip.

[0006] More preferably, the aluminum foil bag body has an internal barrier component, which includes a PE inner layer fixedly connected to the inside of the aluminum foil bag body. A barrier aluminum foil layer is fixedly connected to one side of the PE inner layer. By installing the barrier component, the PE inner layer inside the aluminum foil bag body can play a role in waterproofing and moisture prevention, preventing the food inside from getting damp. At the same time, the barrier aluminum foil layer can improve the barrier performance and protect the freshness and quality of the product. The nylon outer layer of the aluminum foil bag body can effectively enhance the structural strength and sealing performance of the packaging bag, while also having good moisture-proof performance, thus improving the practicality of the device.

[0007] More preferably, a polyethylene middle layer is fixedly connected to one side of the barrier aluminum foil layer, and a nylon outer layer is fixedly connected to one side of the polyethylene middle layer.

[0008] More preferably, an observation film is fixedly connected to the front of the aluminum foil bag body, and a support base is fixedly connected to the bottom of the aluminum foil bag body, with a support opening at the bottom of the support base.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] In this invention, by installing a sealing component, when it is necessary to open the aluminum foil bag body, the aluminum foil bag body can be pinched tightly first, and then the flat dotted line on the sealing strip can be used to make the cut of the sealing strip more even. The convenient tear hole makes it easier to tear the aluminum foil bag body. At this time, by pulling the arc-shaped tear hole, half of the sealing strip can be torn off, and by pulling the other half of the sealing strip, the aluminum foil bag body can be easily opened. This avoids the situation where the sealing strip is completely torn off, which would make it difficult to open the aluminum foil bag body, thus improving the practicality of the device.

[0011] In this invention, by installing a barrier component, the inner PE layer of the aluminum foil bag acts as a waterproof and moisture-proof layer, preventing the food inside from getting damp. Simultaneously, the barrier aluminum foil layer enhances the barrier performance, protecting the product's freshness and quality. Furthermore, the outer nylon layer of the aluminum foil bag effectively strengthens the packaging's structural strength and sealing performance, while also providing excellent moisture resistance, thus improving the device's practicality.
