White BOPP Roll Labels are made of glossy, white biaxially-oriented polypropylene (BOPP) with a permanent adhesive that adheres well to a variety of surfaces. While BOPP is oil and water resistant, we only recommended it for indoor use. With their easy application, these custom roll labels offer full-color brand impact that really sticks! Easily applied to a wide variety of surfaces while serving a variety of purposes including bottles, jars, packaging, boxes, and more.
