This creation relates to a composite layer structure for reposting, and more particularly to a composite layer structure suitable for packaging, tying, adhering, attaching or enclosing articles.

The market is full of various functional tapes. If it is distinguished by the number of layers of tape, it can be generally divided into single-layer tapes and multi-layer tapes. Among them, the single-layer tape refers to a single belt layer, and one side is covered with adhesive, which is often used for sealing, packaging, bundling, and fixing, and is very common. In addition, the multi-layer tape refers to a belt layer including two or more layers, such as a common double-sided tape, a transfer tape, and the like.

Furthermore, the conventional technique for the multi-layer tape can be referred to the "tape structure" of the Japanese Patent No. M370599, which discloses a three-layer belt layer, which is a first release paper layer, a PET substrate, and a second release paper layer. And the three-layer strip layer respectively includes an acrylic adhesive layer and a silicone layer; and when used, the first release paper layer and the second release paper layer are respectively removed, Attach the object to be attached to the PET substrate.
