Waterproof A4 vinyl sticker label sheets, sized to standard A4 paper dimensions (210mm × 297mm), are compatible with inkjet or laser printers, digital printers, and professional wide-format printers. They feature a high-resolution gloss or matte laminate on the surface, offering excellent color reproduction, sharp and vibrant images, as well as superior resistance to water, scratches, oil, and UV exposure, ensuring long-term durability both indoors and outdoors without fading or damage. The back of these vinyl stickers is coated with a strong permanent adhesive, allowing secure bonding to various smooth or semi-smooth surfaces such as glass, plastic, metal, walls, vehicles, and electronic devices. They are ideal for creating identification signs, product labels, decorative decals, advertising graphics, vehicle decals, and equipment labels.
