Description

Technical Field

[0001] The utility model relates to the technical field of packaging plastic films, and specifically relates to a new type of anti-tensile packaging plastic film. Background Art

[0002] Packaging plastic films are mainly made of polymers such as polyethylene, polypropylene, polyvinyl chloride, etc., and are processed into film shapes through a series of processes. Due to their excellent properties such as waterproof, moisture-proof, dust-proof, anti-oxidation, corrosion-resistant, easy to process, etc., these materials are widely used in various fields. Packaging plastic films are soft, light, and thin, and are easy to shape, making them very suitable for packaging various items of different shapes and sizes. It can not only be wrapped conveniently and quickly, but also significantly reduce the extra burden caused by weight increase during transportation. During the packaging process, using packaging plastic films can perform wrapping operations conveniently and quickly. Compared with traditional packaging materials, it can complete the packaging work easily without complex tools and steps. This not only improves packaging efficiency but also reduces labor costs. In addition, the lightweight characteristic of packaging plastic films also significantly reduces the extra burden caused by weight increase during transportation and reduces transportation costs.

[0003] After retrieval, the patent document (the authorized announcement number is CN 219044189 U) provides a new type of anti-tensile packaging plastic film, which includes an upper plastic film layer and a lower plastic film layer, and a tensile core layer is arranged between the upper plastic film layer and the lower plastic film layer; the tensile core layer includes strip-shaped transverse metal wire braided strips and longitudinal wire braided strips, and the transverse metal wire braided strips and the longitudinal wire braided strips are interwoven into a tensile mesh structure; a connecting glue layer is wrapped on the outer surface of the tensile mesh structure. This device solves the technical problem that the plastic film cover is prone to deformation when subjected to a large tensile force, has a poor anti-tensile effect, and is not conducive to forming good protection for the packaged object, and achieves a strong anti-tensile and anti-puncture technical effect.

[0004] However, the above device still has deficiencies:

[0005] The ductility of the grid-shaped ductile plastic bag is usually limited by the arrangement and size of the grid, and shows weak ductility performance in some directions. Content of the Utility Model

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, the utility model proposes a new type of anti-tensile packaging plastic film, which solves the problem that the ductility of the grid-shaped ductile plastic bag is usually limited by the arrangement and size of the grid and shows weak ductility performance in some directions.

[0007] To achieve the above object, the present utility model provides a novel anti-tensile packaging plastic film, which comprises an upper plastic film layer. A lower plastic film layer is arranged below the upper plastic film layer. A plurality of wave buffer layers are arranged in the region surrounded by the upper plastic film layer and the lower plastic film layer. The wave buffer layers are in a wave shape, and a plurality of tensile ribs are inserted into the wave buffer layers.

[0008] Preferably, a soft cushion layer is fixedly connected to the lower surface of the upper plastic film layer, and a heat insulation layer is fixedly connected to the upper surface of the lower plastic film layer.

[0009] Preferably, the wave buffer layers are arranged between the soft cushion layer and the heat insulation layer.

[0010] Preferably, a plurality of connecting ribs are arranged between the soft cushion layer and the heat insulation layer. The connecting ribs are fixedly connected to the side walls of the wave buffer layers, and the connecting ribs are in an X shape.

[0011] Preferably, a protective sleeve is arranged on the side wall of the upper plastic film layer. The protective sleeve is fixedly connected to the outside of the upper plastic film layer, the soft cushion layer, the heat insulation layer and the lower plastic film layer.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Through the arrangement of the wave buffer layers and the tensile ribs, it can be achieved that through the wave-shaped design of the wave buffer layers and the combination of the tensile ribs and the wave buffer layers, the overall structural strength of the device can be greatly improved. The wave-shaped structure of the wave buffer layers can effectively disperse the pressure generated when the plastic bag is stretched, avoiding excessive stress concentration at a single point, thereby improving the overall anti-tensile ability. Compared with the planar structure, the wave-shaped structure provides more support points, increasing the strength of the plastic bag, enabling it to withstand greater tensile force without being easily broken. Improving the anti-tensile ability of the plastic bag reduces the resource consumption caused by frequent replacement or repair, and reduces the carbon emissions generated by frequent production and treatment of plastic bags, meeting the requirements of environmental protection and sustainable development.

[0019] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figures 1-4 shown, a new type of anti-tensile packaging plastic film includes an upper plastic film layer 1. A lower plastic film layer 101 is arranged below the upper plastic film layer 1. A plurality of wave buffer layers 5 are arranged in the area surrounded by the upper plastic film layer 1 and the lower plastic film layer 101. The wave buffer layers 5 are in a wave shape. A plurality of tensile ribs 6 are inserted into the wave buffer layers 5. Through the wave-shaped design of the wave buffer layers 5 and the combination of the tensile ribs 6 and the wave buffer layers 5, the overall structural strength of the device can be greatly improved. The wave-shaped structure of the wave buffer layers 5 can effectively disperse the pressure generated when the plastic bag is stretched, avoiding excessive stress concentration at a single point, thereby improving the overall anti-tensile ability. Compared with the planar structure, the wave-shaped structure provides more support points, increases the strength of the plastic bag, enables it to withstand greater tensile force without being easily broken. Improving the anti-tensile ability of the plastic bag reduces the resource consumption caused by frequent replacement or repair, and reduces the carbon emissions generated by frequent production and treatment of plastic bags, meeting the requirements of environmental protection and sustainable development.

[0021] The lower surface of the upper plastic film layer 1 is fixedly connected with a soft cushion layer 3. The upper surface of the lower plastic film layer 101 is fixedly connected with a heat insulation layer 4. The heat insulation layer 4 can improve the durability of the plastic film, enable it to withstand higher temperatures, and improve the customer's usage satisfaction.

The connecting ribs 7 are fixedly connected to the side walls of the wave buffer layers 5. The connecting ribs 7 are in an X shape. The connecting ribs 7 are used to connect two wave buffer layers 5, which can strengthen the lateral and vertical ductility and stretchability of the device, thereby playing an auxiliary role for the wave buffer layers 5.
