  • Patent number: 11915621
    Abstract: A label sticker is provided and includes: a base layer; a release layer coated on an upper surface of the base layer; a first surface material layer having a lower surface coated with a first glue layer and coated on or adhered to the release layer through the first glue layer; and a second surface material layer having a lower surface coated with a second glue layer and adhered to an upper surface of the first surface material layer through the second glue layer. The area of the second surface material layer is greater than the area of the first surface material layer. The label sticker. Therefore, glue residues left behind by a process of making the label sticker do not interfere with use thereof.

  • Publication number: 20200079978
    Abstract: A label sticker includes a base layer; a release layer coated on an upper surface of the base layer; a first face material layer with a lower surface which a high-viscosity adhesive layer is coated on or adhered to and the release layer is adhered to through the high-viscosity adhesive layer; and a second face material layer with a lower surface which a low-viscosity adhesive layer is coated on and the upper surface of the first face material layer is adhered to through the low-viscosity adhesive layer, with the second face material layer corresponding in shape to and having the same area as the first face material layer. Therefore, the use of the label sticker is free of interference from adhesive remnants left over after processing.
