[0017] The following is in conjunction with the appendix Figs. 1 to 3 This utility model will be described in detail.
[0018] This utility model is a high-toughness cardboard cable tie, including a wire core 1, and also including an upper covering layer 2 and a lower covering layer 3; as shown Fig. 3 As shown, the upper covering layer 2 includes a first cardboard layer 21 and a first film layer 22 stacked sequentially from top to bottom; the lower covering layer 3 includes a second cardboard layer 31 and a second film layer 32 stacked sequentially from bottom to top; the upper covering layer 2 and the lower covering layer 3 cover the wire core 1 from opposite sides and form a first wing 4 and a second wing 5 on both sides of the wire core 1. This invention uses a method where the first cardboard layer 21 and the second cardboard layer 31 sandwich a film layer. The toughness of the film layer effectively improves the toughness of the cable tie, making it less prone to tearing during use, extending its service life, and reducing the need for frequent replacements. This saves labor, brings more convenience to the use of cable ties, and better meets the existing user needs for cable ties.
[0019] In the technical solution, the thickness of the film layer is only between 0.1-2mm, and even if it is sandwiched between the first paper layer and the second paper layer, the adhesion of the upper and lower paper layers is not affected at all.
[0020] As an embodiment, the first paper layer 21 and the second paper layer 31 are both kraft paper layers. On the one hand, the raw material cost of kraft paper layer is low, and it is more suitable for factory mass production. On the other hand, the kraft paper layer has high environmental protection, and the produced cable tie is more environmentally friendly and will not have adverse effects on the environment.
[0021] As an embodiment, the first film layer 22 and the second film layer 32 are both polyurethane films. The polyurethane film has moderate thickness and high toughness, and is not easy to be torn, so that the cable tie as a whole has high toughness.
[0022] As preferred, the wire core 1 is formed of metal material, and the wire core 1 can adopt copper strip, iron strip or aluminum strip. The wire core 1 made of metal material has better ductility and strength, and is not easy to break, so that the cable tie can be conveniently bent and tied at will, and the wire core 1 of the waste cable tie can be recycled and reused.
[0023] In the technical solution, the first paper layer 21 and the first film layer 22, and the first film layer 22 and the wire core 1 are both provided with the first glue layer 6. At the same time, the second paper layer 31 and the second film layer 32, and the second film layer 32 and the wire core 1 are both provided with the second glue layer 7. When the cable tie is formed, the lower surface of the first paper layer 21 and the first film layer 22 is preferentially coated with the first glue layer 6; the upper surface of the second paper layer 31 and the second film layer 32 is preferentially coated with the second glue layer 7, and the upper and lower cladding layers 3 are respectively bonded and formed, and then the linearly formed cable tie is coated. In order to improve the environmental protection performance of the cable tie, the first glue layer 6 and the second glue layer 7 adopt environmentally friendly glue.
[0024] As preferred, in order to enable the upper cladding layer 2 and the lower cladding layer 3 to be sealed and adhered, and prevent the side edge from being cracked, the two side edges of the first paper layer 21 and the second paper layer 31 are both provided with the arc part 8 which facilitates the joint of the paper layer.
[0025] The above is only a preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation and application range can be changed, and the content of the specification should not be understood as a limitation of the present application.
