1 is a schematic cross-sectional view of an eco-friendly label according to an embodiment.

Referring to FIG. 1, an eco-friendly label 1 according to an embodiment may be applied to a container of a product. For example, the eco-friendly label 1 can be applied to a cup beverage container. The eco-friendly label 1 has a blocking power against oxygen and moisture, thereby preserving the product contained in the container. The eco-friendly label 1 can be formed of a single material to facilitate recycling.

The eco-friendly label 1 according to an embodiment may include a first layer 11, a second layer 12, and an adhesive layer 13.

The first layer 11 may be a layer positioned outside the eco-friendly label 1. The first layer 11 may be coated in-line. The first layer 11 may include a printed layer 111, a blocking layer 112 and a textured layer 113.

Product information or a design may be printed on the print layer 111. The printing layer 111 may improve the stability and durability of the eco-friendly label 1. For example, the printing layer 111 may include an oriented polypropylene (OPP) material.

The blocking layer 112 may be laminated on one surface of the printing layer 111. The blocking layer 112 may have blocking power against oxygen and moisture. For example, the blocking layer 112 may include a poly vinyl alcohol (PVA) material. The blocking layer 112 may be formed by dissolving PVA resin with an aqueous coating agent and then coating it on one surface of the printing layer 111.

The texture layer 113 may be stacked on the other surface of the print layer 111. The texture layer 113 may constitute an outer surface of the eco-friendly label 1. The texture layer 113 may provide a soft texture. The texture layer 113 may provide a premium feeling to the consumer through touch. For example, the texture layer 113 may be formed by applying a Soft Feel OP coating agent to which a polyether type urethane binder is applied on the other surface of the printing layer 111.

The second layer 12 may be a layer positioned inside the eco-friendly label 1. The second layer 12 may include an adhesion layer 121 and an aluminum deposition layer 122.

The adhesion layer 121 may constitute the inner surface of the eco-friendly label 1. The adhesion layer 121 may be a layer that is in close contact with the container. The adhesion layer 121 may have adhesion. The adhesion layer 121 may include a material of the same series as the printing layer 111. Since the adhesion layer 121 and the printing layer 111 include the same series of materials, the eco-friendly label 1 can be easily recycled. The adhesion layer 121 may have more matt characteristics than the printing layer 111. For example, the adhesion layer 121 may include a Matt OPP material.

The aluminum deposition layer 122 may be formed on one surface of the adhesion layer 121. For example, the aluminum deposition layer 122 may be formed by depositing aluminum on one surface of the adhesion layer 121. The aluminum deposition layer 122 may have blocking power against oxygen and moisture. In addition, since the aluminum deposition layer 122 is formed by a deposition method, recycling characteristics may be improved.

The adhesive layer 13 may bond the first layer 11 and the second layer 12. Specifically, the adhesive layer 13 may bond the blocking layer 112 of the first layer 11 and the aluminum deposition layer 122 of the second layer 12 to each other. The eco-friendly label 1 may have a high blocking power by the blocking layer 112 and the aluminum deposition layer 122. The adhesive layer 13 may be applied by an eco-friendly construction method. For example, the adhesive layer 13 may bond the first layer 11 and the second layer 12 by solvent-free adhesion.

2 and 3, according to an eco-friendly label manufacturing method (2) according to an embodiment, an eco-friendly label that can be easily recycled can be manufactured. The eco-friendly label manufacturing method (2) may be applied to an eco-friendly method.

2 and 3, the method 2 for manufacturing an eco-friendly label according to an embodiment may include a first layer forming step 21, a second layer forming step 22 and an adhesive step 23. .

The first layer forming step 21 may be a step in which a first layer is formed by forming a blocking layer and / or a texture layer on the printed layer. For example, the printed layer may include OPP material. The first layer forming step 21 may include a blocking layer forming step 211 and a textured layer forming step 212. The first layer forming step 21 may be a step formed by an in-line coating.

The blocking layer forming step 211 may be a step in which a blocking layer is coated on one surface of the printing layer. For example, the blocking layer may be formed by dissolving PVA (Poly Vinyl Alcohol) as an aqueous coating agent and coating it on one surface of the printing layer. The barrier layer may have barrier properties against moisture and oxygen.

The texture layer forming step 212 may be a step of forming a texture layer by applying a coating agent applied with a polyether type urethane binder to the other surface of the printing layer. The texture layer can provide a soft texture.

The second layer forming step 22 may be a step in which aluminum is deposited on one surface of the adhesion layer to form a second layer. The adhesion layer may have adhesion to the container. The adhesion layer may include the same series of materials as the printing layer. The adhesion layer may have a more matte characteristic than the printing layer. For example, the adhesion layer may include a Matt OPP material. The aluminum deposition layer formed by depositing on one surface of the adhesion layer may have a blocking force.

The bonding step 23 may be a step in which the first layer and the second layer are bonded. Specifically, the bonding step 23 may be a step of bonding the blocking layer of the first layer and the aluminum deposition layer of the second layer. The adhesion step 23 may be applied to an environmentally friendly construction method. For example, the adhesion step 23 may proceed with solvent-free adhesion.
