Abstract

The invention discloses a PET (Polyethylene Terephthalate) composite film structure. The PET composite film structure comprises a PET highly-transparent film, wherein one surface of the PET highly-transparent film is attached with a PET release film layer by a coloring layer, and the other surface of the PET highly-transparent film is attached with a first non-woven fabric layer; one surface, separated from the PET highly-transparent film, of the first non-woven fabric layer is attached with a conducting layer, a second non-woven fabric layer, a copper-wire shielding layer and a protective layer in sequence from inside to outside; the thickness of the protective layer is 0.25-3mm. The PET composite film structure provided by the invention has the beneficial effects that with arrangement ofthe coloring layer, convenience is brought for coloring and printing; the shape is displayed by the PET highly-transparent film with good transparency; the PET release film layer facilitates detachment; the non-woven fabric layer plays a certain role in protection to buffer acting force on the PET composite film structure, and has the functions of conduction, electric shielding and fireproofing,and the thickness of the protective layer is in a certain range, so that the service life of the PET composite film structure is prolonged; the structure is simple and the application prospect is wide.

Description

Technical field [0001] The invention belongs to the field of PET films, and specifically relates to a PET composite film structure. Background technique [0002] PET film is widely used in many fields. With the upgrading of electronic products, its requirements for the structure of PET film have also increased. Conventional PET film can no longer fully meet the needs. For this reason, a more practical design is designed And the fully functional PET structure has important practical significance. Summary of the invention [0003] In order to solve the problems in the prior art, the present invention provides a PET composite film structure. [0004] In order to achieve the above objectives, the technical solutions adopted by the present invention are: [0005] A PET composite film structure includes a PET high-permeability film. One side of the PET high-permeability film is bonded to the PET release film layer through a colored layer, and the other side of the PET high-permeability fi...
