Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil packaging, in particular to a medicinal aluminum foil packaging bag. Background Art

[0002] Aluminum foil packaging bags are made by laminating multiple plastic films and then using a bag-making machine to form bags. They are used to package food, pharmaceuticals, industrial products, daily necessities, and more. Aluminum foil is a common packaging material used in the food industry, and is most common in the packaging of traditional Chinese medicines. Traditional Chinese medicines are typically measured in quantities sufficient for multiple courses of treatment, so large quantities cannot be consumed in a short period of time. Therefore, the preservation of these herbs requires light-shielding and moisture-proofing to ensure optimal quality. Aluminum foil is lightweight, moisture-proof, highly airtight, light-shielding, and wear-resistant, effectively shielding against moisture, ultraviolet rays, and bacteria in the air. Furthermore, it is easy to process and shape, making it a popular material for pharmaceutical packaging. Traditional pharmaceutical aluminum foil packaging has a simple structure, and once opened, the packaging cannot be easily sealed for storage. It usually requires additional clamps or other items to secure it. This significantly reduces the packaging's moisture resistance, making the medicine inside the bag susceptible to moisture and unusable. To address this issue, we have proposed a pharmaceutical aluminum foil packaging bag. Utility Model Content

[0003] To address the above-mentioned issues, the present invention provides a pharmaceutical aluminum foil packaging bag. This solves the problem that conventional pharmaceutical aluminum foil packaging has a simple structure, cannot be easily sealed and stored after being torn, and usually requires additional clamps or other items to clamp it, which greatly reduces the moisture resistance of the packaging and easily causes the medicine in the packaging bag to become damp and unusable.

[0004] The utility model provides a medicinal aluminum foil packaging bag, comprising a packaging bag body, wherein the packaging bag body comprises a bottom edge, side edges are provided on both sides above the bottom edge, both sides of the two side edges are fixedly connected by connecting edges, a fixing strip is provided on the side where the upper ends of the two side edges are close to each other, one of the fixing strips is provided with a connecting plate on the side away from the side edge, a positioning strip is provided on the side of the connecting plate away from the fixing strip, and a positioning groove matching the positioning strip is provided on the other fixing strip, the bottom edge, side edges and connecting edges have the same structure, the bottom edge comprises an aluminum foil layer, a waterproof layer is provided on one side of the aluminum foil layer, and a heat insulation layer is provided on the side of the aluminum foil layer away from the waterproof layer.

[0005] In the above solution, a composite adhesive layer is provided between the heat insulation layer and the aluminum foil layer.

[0006] In the above solution, the waterproof layer is a polyurethane film layer.

[0007] In the above solution, a fold is provided on the connecting edge.

[0008] In the above solution, the side of the positioning strip away from the connecting plate is configured as an arc surface.

[0009] In the above solution, a label frame is provided on the outer side of one of the side edges.

[0010] In the above solution, the upper ends of the two side edges are fixedly connected, and open grooves are provided on both sides of the upper ends of the side edges.

[0011] The advantages and beneficial effects of the present invention are as follows: the present invention provides a medicinal aluminum foil packaging bag, wherein the positioning strip is inserted into the positioning groove. The positioning strip and the positioning groove cooperate with each other to allow the upper end of the packaging bag body to be resealed after opening. The waterproof layer effectively enhances the waterproof performance of the packaging bag body, and the heat insulation layer effectively enhances the heat insulation performance of the packaging bag body. The aluminum foil packaging bag has a simple structure and good waterproof and heat insulation effects. The packaging bag can be resealed after opening, preventing the phenomenon of the medicine becoming unusable due to moisture. BRIEF DESCRIPTION OF THE DRAWINGS
