A PET drum with an electrically conductive layer attached to an inn layer

A PET rotary drum with an electrically conductive layer attached to an inn layer includes a main body having a long cylindrical shape and a hollow structure and a first composite layer comprising a copper foil and a PET film layer, wherein the copper foil surrounds the main body, the PET film layer surrounds the copper foil, and an adhesive is arranged between the copper foil and the main body. Through mutual cooperation of the main body, the first composite layer and the second composite layer, the copper foil protects the main body from being punctured by sharp objects, and the copper foil can also be used as a medium for transmitting electric current in a comparatively safe environment. 本发明涉及种内层附有导电层PET转筒，其包括主体，所述主体为长筒状，所述主体为中空结构；第复合层，所述第复合层包括铜箔和PET薄膜层，所述铜箔环绕在所述主体外，所述PET薄膜层环绕在所述铜箔外，所述铜箔和所述主体之间设有粘合剂。通过所述主体、所述第复合层和所述第二复合层相互配合，所述铜箔保护所述主体，避免所述主体被尖锐的物体刺穿，且在较为安全的环境下，所述铜箔还可以作为传输电流的介质。
