[0002] Aluminum-plastic composite tape for optical cables is a material with important applications in fields such as optical cable manufacturing. It is usually a multi-layer structure material made of aluminum foil and plastic film through a composite process. The outer aluminum foil generally has good metallic properties, such as good conductivity and barrier properties, while the inner plastic film often plays a role in enhancing flexibility, protecting the aluminum foil, and facilitating bonding with other materials. Common plastic film materials include polyethylene and polypropylene.

[0003] Currently, aluminum-plastic composite tape is used to wrap cables to protect them and prevent moisture from entering the cable when it is buried underground. The aluminum-plastic composite tape has excellent barrier properties, and its aluminum foil layer and plastic film layer work together to effectively block the intrusion of external moisture, creating a relatively dry environment inside the cable. However, the aluminum-plastic composite tape is prone to tearing during wrapping, which causes cracks in the plastic film layer and reduces the protective effect.

The multiple inclined plates 15 are interlocked and fixedly connected together, and the four ends of two inclined plates 15 are respectively fixedly connected to one side of two partition plates 16, thereby forming multiple triangular cavities inside the heat insulation cavity 14. This increases the stability of the main body 1, while also giving the main body 1 a certain buffering effect and increasing the protective effect of the main body 1.

[0052] One end of the inclined plate 15 is fixedly connected to a partition plate 16, and one side of the partition plate 16 is fixedly connected to a baffle plate 17.
