Description

Technical Field

[0001] The utility model belongs to the field of plastic woven bags, in particular to a film-covered plastic woven bag. Background Art

[0002] Woven bags play an important role in cargo transportation. In order to protect the cargo from moisture, a layer of plastic film is usually placed inside the woven bag. However, the material is poor and is easily damaged or soiled, and cannot be reused. In addition, the material of conventional woven bags is also easily worn during use, causing damage to the bag body and making it impossible to continue recycling, which results in a waste of resources.

[0003] A film-coated woven bag (patent application number: CN202320344937.5) is currently disclosed, which includes a woven bag body and two handles, the two handles are respectively fixedly connected to the front outer wall and the rear outer wall of the woven bag body, and a storage opening is opened on the top of the woven bag body. The woven bag body includes an outer woven layer, an insulation layer, an inner woven layer, an inner film layer and a flame retardant layer. The insulation layer is fixedly connected to the inner wall of the outer woven layer, the inner woven layer is fixedly connected to the inner wall of the insulation layer, the inner film layer is fixedly connected to the inner wall of the inner woven layer, and the flame retardant layer is fixedly connected to the outer wall of the outer woven layer. The outer woven layer and the inner woven layer are both made of PE plastic, the insulation layer is made of rock wool material, and the inner film layer is made of EVA film material.

[0004] The woven bag has a multi-layer structure, which not only increases the functions of waterproofing, heat preservation, and flame retardancy, but also improves the wear resistance. It can improve the wear resistance to a certain extent. However, there is no replaceable film inside the woven bag, and the inner film is fixed to the bag body. When the inside of the woven bag is damaged or soiled due to filling items, only a new woven bag can be used, which easily causes a waste of resources. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A coated plastic woven bag comprises a bag body, an inner bag is arranged inside the bag body, a first zipper rack is connected to the inner side of the bottom of the bag body, a second zipper rack is connected to the outer side of the bottom of the inner bag, the first zipper rack or the second zipper rack is slidably connected to a pull head, the first zipper rack and the second zipper rack are connected and fixed by the pull head, the bag body is composed of a woven layer and a wear-resistant layer, and the woven layer is located on the inner side of the wear-resistant layer.

[0008] Preferably, a connection area is provided at the upper end of the bag body, a mother patch is fixed on the inner side of the connection area, a child patch is fixed on the outer side of the upper end of the inner bag, and the child patch is bonded to the mother patch.

[0009] Preferably, a sealing structure is provided at the upper end of the bag body, and the sealing structure is located above the mother patch.

[0010] Preferably, an anti-scratch edge is provided at the bag opening of the bag body.

[0011] Preferably, the material of the anti-scratch edge is the same as that of the bag body, and the anti-scratch edge is a double-layer or triple-layer structure.

[0012] Preferably, a rubber pad is sewn or bonded on at least one side of the outer side of the bag body.

[0013] Preferably, the inner bag is made of PVC material.

[0014] Preferably, the bag body is connected to the first zipper rack by sewing, and the inner bag is connected to the second zipper rack by sewing.

[0015] The utility model has the following beneficial effects:

[0016] (1) A detachable inner bag is arranged inside the woven bag body, and the inner bag is connected to the bag body by a zipper structure, which is convenient for disassembly and installation, so that the inner bag can be disassembled and replaced when it is damaged or dirty, thereby reducing resource waste;

[0017] (2) The inner bag is made of PVC material, which has good anti-corrosion and waterproof properties, which can prevent the items in the inner bag from being damaged by moisture and ensure quality;

[0018] (3) The bag body is composed of a woven layer and a wear-resistant layer. The woven layer forms the bag body structure, and the wear-resistant layer is attached to the outer surface of the woven layer to improve the wear resistance, extend the service life of the woven bag, and reduce resource waste.
