We usually do waterproof lamination on the surface of the Adhesive Food Sticker Label. Generally, we will cover the surface of the label with glossy film, matte film or oil. As for glue, we will also recommend different glues, such as hot melt glue, oil glue, water glue, and viscose glue, through the surface of the customer's paste. Our material itself has been waterproofed, and the materials used for food labels are: Vinyl, BOPP, PVC, PET, Art Paper, etc, with gold stamping, hot foil, spot UV or embossed of printing processes.
