Abstract
Description
Technical Field
[0001] This utility model belongs to the field of membrane technology and relates to a PVC film for transportation protection. Background Technology
[0002] PVC film is a widely used protective material in the transportation of various goods. It can effectively protect the goods from scratches, abrasions, contamination or other potential damage during transportation.
[0003] Currently available PVC films are either single-layer thin films that require multiple layers to be rolled up before use, or simple double-layer films with air bubbles that need to be secured with tape. Neither of these types is convenient for repeated use and has low overall economic value; therefore, it is necessary to design a PVC film for transportation protection. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a PVC film for transportation protection.
[0005] The objective of this utility model can be achieved through the following technical solution: A PVC film for transportation protection, characterized in that it comprises an upper film and a lower film, the upper film and the lower film being co-extruded to form a rectangular body, the upper film and the lower film having multiple strip-shaped air cavities between them, the air cavities also having two sets of notches arranged in a straight line, and the notches being arranged on the upper film, the side of the body being connected to two fabric strips, the outer end of the fabric strips having a block-shaped sub-adhesive, and the inner end of the fabric strips having a strip-shaped female adhesive.
[0006] The fabric strip also has an anti-slip layer.
[0007] The anti-slip layer is a dotted plastic layer or a silicone layer.
[0008] The fabric strip also has a reinforcing piece between it and the main body.
[0009] Compared with existing technologies, this PVC film for transport protection has the following advantages:
[0010] This invention features multiple air chambers on the main body with notches, allowing the PVC film to be reliably connected to the item to be protected via a cloth strip; furthermore, the PVC film is easy to disassemble and reuse. Attached Figure Description

[0012] Figure 2This is a front structural diagram of the present invention;
[0013] Figure 3 This is a schematic diagram of the reverse side structure of this utility model;
[0014] In the figure, 10 is the main body; 10a is the upper membrane; 10b is the lower membrane; 101 is the air cavity; 102 is the notch; 20 is the mother patch; 30 is the cloth strip; 40 is the anti-slip layer; 50 is the daughter patch; and 60 is the reinforcing sheet. Detailed Implementation
[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0016] like Figures 1-3 As shown, the PVC film for transportation protection includes an upper film 10a and a lower film 10b. The upper film 10a and the lower film 10b are co-extruded to form a rectangular body 10, which is manufactured using existing technology. Multiple strip-shaped air cavities 101 are located between the upper film 10a and the lower film 10b. Each air cavity 101 has two sets of recesses 102 arranged in a straight line, and the recesses 102 are located on the upper film 10a. The side of the body 10 is connected to two fabric strips 30. In practice, the fabric strips 30 can be made of warp-knitted fabric. Specifically, there is a reinforcing piece 60 between the fabric strips 30 and the body 10. The fabric strips 30 can be directly sewn to the side of the body 10 with stitching thread. The outer end of the fabric strips 30 has a block-shaped sub-attachment 50, and the inner end of the fabric strips 30 has a strip-shaped female attachment 20. The sub-attachment 50 and the female attachment 20 are existing products that can be purchased on the market, and the two can be reliably connected.
[0017] The fabric strip 30 also has an anti-slip layer 40; the anti-slip layer 40 is a dotted plastic layer or a silicone layer.
[0018] This utility model provides multiple air chambers 101 on the main body and provides notches 102 on the air chambers 101, so that the PVC film can be reliably connected to the item to be protected by the cloth strip 30. When in use, the cloth strip 30 is just stuck in the notch 102. After the cloth strip 30 is wrapped around, the sub-adhesive 50 is attached to the female adhesive 20. In addition, the PVC film is easy to disassemble and reuse.
[0019] In this practice, the size of the body 10 can be changed as needed.
[0020] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
