[0008] The terms used herein are not intended to limit the invention but to describe particular embodiments. As used herein, the singular forms "a," "an," and "the" can include the plural unless the context clearly dictates otherwise.

[0009] The directional terms used in this specification, such as up, down, left, right, front, rear, and their derivatives or synonyms, do not limit the present invention but relate to the orientation of elements in the drawings. Unless otherwise clearly stated in the context or to clearly show the features of the present invention, the present invention is not described based on actual dimensional relationships. The technical content of the present invention will be described in detail below with reference to the drawings. Referring to FIG. 1, a first embodiment of the present invention discloses a transparent paper adhesive tape 1 that can be wound around an annular bracket 1a so that a user can use the transparent paper adhesive tape 1 through an auxiliary device (e.g., a tape dispenser).

[0010] Referring to FIG. 2, the transparent paper adhesive tape 1 has a thickness t1, which is between 40 μm and 80 μm, and includes a transparent paper substrate layer 10, a transparent surface layer 20, and an adhesive layer 30.

[0011] The transparent paper substrate layer 10 has a top surface 11, a bottom surface 12, and a transparent paper fiber structure 13, the top surface 11 and the bottom surface 12 being located on opposite sides, and the transparent paper fiber structure 13 being located between the top surface 11 and the bottom surface 12, and the transparent paper fiber structure 13 is optically transparent so that light can pass through the transparent paper substrate layer 10. The use of the transparent paper fiber structure 13 avoids the problems of environmental pollution and adverse health effects caused by using petrochemical raw materials as the substrate, significantly reduces the amount of petrochemical raw materials used, and improves the environmental friendliness of the product as a whole.

[0012] The transparent surface layer 20 is disposed on the upper surface 11 of the transparent paper substrate layer 10 and has a multifunctional surface 21. The multifunctional surface 21 is transparent and has a plurality of functional properties, including, but not limited to, light transmission, writability, printability, thermal transferability, waterproofness, oil resistance, or a combination thereof. In one example, the transparent surface layer 20 has a plurality of functional properties because the upper surface 11 of the transparent paper substrate layer 10 is coated with one or more layers of a treatment agent, including, but not limited to, polyurethane, polyvinyl alcohol, polyvinylpyrrolidone, polyester, nylon, fluororesin, siloxane, or a combination thereof.

[0013] The adhesive layer 30 is provided on the bottom surface 12 of the transparent paper base layer 10 and has adhesive properties. In this example, the adhesive layer 30 is a pressure-sensitive adhesive (PSA) layer, which may be, but is not limited to, a rubber-based pressure-sensitive adhesive or an acrylic-based pressure-sensitive adhesive.

[0014] Referring to Figure 3, the adhesive layer 30 is configured to be releasably adhered to the multi-functional characteristic surface 21 of the transparent surface layer 20 when the transparent paper adhesive tape 1 is divided into multiple layers and wound around the annular bracket 1a, i.e., the transparent surface layer 20 is a release layer relative to the adhesive layer 30.

[0015] Referring to Figure 4, a second embodiment of the present invention discloses a transparent paper label 2, on which one or more trademark designs 2a can be printed. The second embodiment has a similar structure and material composition to the first embodiment, thereby achieving the technical feature of significantly reducing the amount of petrochemical raw materials used and improving the environmental friendliness of the entire product.

[0016] Referring to FIG. 5, the transparent paper label 2 has a thickness t2, which is between 50 μm and 300 μm, and includes a transparent paper substrate layer 40, a transparent surface layer 50, an adhesive layer 60, and a release layer 70.

[0017] The transparent paper substrate layer 40 has a top surface 41, a bottom surface 42, and a transparent paper fiber structure 43, the top surface 41 and the bottom surface 42 being located on opposite sides, the transparent paper fiber structure 43 being located between the top surface 41 and the bottom surface 42, and the transparent paper fiber structure 43 being light-transmitting so as to allow light to pass through the transparent paper substrate layer 40.

[0018] The transparent surface layer 50 is disposed on the upper surface 41 of the transparent paper substrate layer 40 and has a multifunctional surface 51. The multifunctional surface 51 is transparent and has multiple functional properties, including, but not limited to, light transmittance, writability, printability, thermal transferability, waterproofness, oil resistance, or a combination thereof. In one example, the transparent surface layer 50 has multiple functional properties because the upper surface 41 of the transparent paper substrate layer 40 is coated with one or more layers of a treatment agent, including, but not limited to, polyurethane, polyvinyl alcohol, polyvinylpyrrolidone, polyester, nylon, fluororesin, siloxane, or a combination thereof. The trademark design 2a is disposed on the multifunctional surface 51.

[0019] The adhesive layer 60 is provided on the bottom surface 42 of the transparent paper base layer 40 and has adhesive properties. In this example, the adhesive layer 60 is a pressure-sensitive adhesive layer, which may be, but is not limited to, a rubber-based pressure-sensitive adhesive or an acrylic-based pressure-sensitive adhesive.

[0020] The release layer 70 is releasably adhered to the adhesive layer 60, and in one example, the release layer 70 may be, but is not limited to, a liner paper, which can function as a protective layer for the adhesive layer 60.

[0021] 6, when using the transparent paper label 2, the release layer 70 is peeled off and the adhesive layer 60 is applied to the intended product 3. In one example, the adhesive layer 60 can be peeled off from the product 3 and applied to it.

[0022] As can be seen from the above, the present invention provides transparent paper adhesive tapes and transparent paper labels with a transparent paper structure, solving the problems of the substrate used in conventional transparent adhesive tapes and transparent labels being made from petrochemical raw materials (e.g., plastic), which causes environmental pollution and has adverse health effects. Furthermore, using a transparent paper structure as a substrate and coating with a treatment agent not only provides good transparency, but also properties such as writability, printability, thermal transferability, waterproofness, and oil resistance. The present invention can significantly reduce the amount of plastic used, improving the overall environmental friendliness and functionality of products, and can replace conventional plastic adhesive tapes and labels, achieving the goal of eliminating plastic in products.
