Abstract

While in typical enamel protection labels, an adhesive layer lies on each silicone-containing separating layer, from which the first is detachable, according to the present invention the separating area is implemented using a material pairing free of adhesive and silicone.

The enamel protection label has two masking layers (7a, 7b), more masking layers are also possible. The upper masking layer (7b) is attached using an adhesive layer (10b) onto the separating layer (8b) made of transparent UV-cured screenprint enamel. This enamel is applied to the lower masking layer (7a), made of a plastic film which is not pretreated further. The separating area (9b) functionally assigned to the upper masking layer (7b) represents the boundary area between separating area (8b) and lower masking layer (7a), along which the detachment for removing the upper masking layer (7b) is performed. After the upper masking layer (7b) is removed, the imprint (2) is visible through the lower masking layer (7a), which lies protected under the masking layer (7) during the first enameling step, and the sealing layer (6). The position and function of the initially remaining lower masking layer (7a), adhesive layer (10a), separating layer (8a), and separating area (9a) functionally assigned to the lower masking layer (7a) during and after the second enameling step are analogous.

Claims

1. An enamel protection label for masking text, image, and/or code information (2) in an enameling process, having

a transparent sealing layer (6),

a self-adhesive coating (3) positioned underneath the sealing layer (6), and

at least one removable masking layer (7, 7a, 7b, 71a, 71b), which covers the sealing layer (6) at least in the region of the text, image, and/or code information (2) and is transparent at least in the region of the coverage of the text, image, and/or code information (2),

a separating area (9, 9a, 9b, 91a, 91b, 92a, 92b) of two layers lying on top of one another being functionally assigned to each masking layer (7, 7a, 7b, 71a, 71b) in such a way that these layers lying on top of one another are separated from one another when the masking layer (7, 7a, 7b, 71a, 71b) is removed,

wherein the separating area (9, 9a, 9b, 91a, 91b, 92a, 92b) is adhesive-free.

2. The enamel protect ion label according to claim 1, wherein one of the layers lying on top of one another at the separating area (9, 9a, 9b, 91a, 91b, 92a, 92b) is made of a transparent enamel, and the other is made of a plastic film.

3. The enamel protection label according to claim 2, wherein the enamel is a UV-cured enamel.

4. The enamel protection label according to claim 2, wherein the enamel is applied using screen printing, letterpress printing, or flexographic printing.

5. The enamel protection label according to claim 2, wherein the enamel is silicone-free.

6. The enamel protection label according to claim 1, wherein, under the sealing layer (6), a base layer (1) which is glued thereto is positioned, whose top is provided with the text, image, and/or code information (2) to be covered, and whose bottom carries the self-adhesive coating (3).

7. The enamel protection label according to claim 1, wherein the sealing layer (6) carries the self-adhesive coating (5) on its bottom.

8. The enamel protection label according to claim 1, wherein the enamel protection label has multiple masking layers (7a, 7b, 71a, 71b), which are positioned one on top of another and are removable one after another.

9. The enamel protection label according to claim 1, wherein the sealing layer (6) adjoins the separating area (9, 9a, 91a) functionally assigned to the proximate masking layer (7, 7a, 71a) lying above it.

10. The enamel protection label according to claim 1, wherein each masking layer (71a, 71b) adjoins the particular separating area (92a, 92b) functionally assigned to it.

11. The enamel protection label according to claim 9, wherein each masking layer (7a, 71a), with the exception of the uppermost masking layer (7b, 71b), adjoins the separating area (9b, 91b) functionally assigned to the particular proximate masking layer lying above it.

12. The enamel protection label according to claim 11, wherein the bottom of each masking layer (7a, 7b) adjoins one adhesive layer (10a, 10b).

13. The enamel protection label according-to claim 1, wherein the label has at least one removal aid functionally assigned to each masking layer (7, 7a, 7b, 71a, 71b).

14. The enamel protection label according to claim 13, wherein the removal aid is a grip tab shaped onto the masking layer (7, 7a, 7b, 71a, 71b) assigned thereto.

15. The enamel protection label according to claim 13, wherein the removal aid is a separate film piece (11, 11a, 11b).

16. The enamel protection label according to claim 13, wherein the removal aid is manufactured through adhesive neutralization using partial printing of an adhesive layer (10a, 10b) adjoining the bottom of the masking layer (7, 7a, 7b, 71a, 71b).

17. The enamel protection label according to claim 13, wherein a narrow region of locally increased adhesion between the masking layer functionally assigned (7, 7a, 7b, 71a, 71b) to the removal aid and the film composite lying underneath is positioned near the removal aid.
