Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to an aluminized film high-barrier packaging bag. Background Art

[0002] Packaging bags refer to bags used to package various items, making it convenient to transport and store goods during the production and circulation process. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags are eventually transported to garbage dumps for treatment like general garbage, and only 7% of plastics are recycled. Packaging bags are often divided into plastic packaging bags and composite packaging bags. Among composite packaging bags, aluminized film high barrier packaging bags are more widely used.

[0003] When using existing aluminized film high-barrier packaging bags, in order to facilitate pouring out the items in the packaging bag, it is necessary to cut an opening in the packaging bag with scissors to facilitate pouring out the items in the packaging bag. However, if the opening is too large, its sealing performance will be affected, and the items in the packaging bag will easily get damp. Therefore, it is necessary to design an aluminized film high-barrier packaging bag. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an aluminized film high-barrier packaging bag.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: an aluminum-coated high-barrier packaging bag, comprising a bag body, a discharge assembly is provided at the front end of the bag body, a sealing assembly is provided at the upper end of the bag body, the sealing assembly is used to seal the upper end of the bag body, and the lower end of the bag body is fixedly connected to a reinforced base.

[0006] As a further description of the above technical solution:

[0007] The bag body consists of an aluminized film layer, a buffer layer and a high-barrier film layer, which are distributed in sequence from the inside to the outside. The buffer layer is arranged on the outside of the aluminized film layer, and the high-barrier film layer is arranged on the outside of the buffer layer.

[0008] As a further description of the above technical solution:

[0009] The discharge assembly includes a discharge pipe and a sealing cover. The front end of the bag body is fixedly connected to the discharge pipe. The discharge pipe is arranged to be inclined upward. The circumferential surface of the discharge pipe away from one end of the bag body is threadedly connected to the sealing cover.

[0010] As a further description of the above technical solution:

[0011] The sealing assembly includes a zipper and a zipper head. The upper end of the bag body is fixedly connected to the zipper, and the zipper head is installed on the zipper.

[0012] As a further description of the above technical solution:

[0013] The front and rear sides of the bag body are both fixedly connected with support blocks, and the upper ends of the support blocks are fixedly connected to the zipper.

[0014] As a further description of the above technical solution:

[0015] A lifting handle is fixedly connected to the side end surface of the bag body, and two lifting handles are provided and symmetrically distributed on the left and right sides of the bag body.

[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, this aluminized film high-barrier packaging bag is provided with a discharge assembly. When the items inside the packaging bag need to be poured out, the sealing cover of the discharge assembly is unscrewed, so that the items inside the bag are conveniently poured out from the discharge pipe. When the items inside the packaging bag are poured out, there is no need to cut an opening on the packaging bag with scissors, thereby reducing damage to the packaging bag and facilitating the recycling of the packaging bag. When the items are not being poured out, the sealing cover is screwed on to achieve the purpose of sealing, thereby effectively preventing the items inside the packaging bag from getting damp.

[0018] 2. Compared with the existing technology, this aluminized film high barrier packaging bag is provided with a zipper and a zipper head. When it is necessary to add items to the inside of the packaging bag, the zipper head is pulled to open the zipper, making it convenient to add items from the upper end of the bag body to the inside of the bag body.

[0019] 3. Compared with the existing technology, this aluminized film high-barrier packaging bag can protect articles by setting up a bag body. Since the bag body is composed of an aluminized film layer, a buffer layer and a high-barrier film layer, the performance of the bag body can be improved, thereby extending the service life of the bag body.
