Sometimes it’s okay to be square – a square label lends clean, attractive edges to frame your information or graphics. Our labels are printed full color pm 2.6 mil white BOPP (polypropylene) with permanent adhesive. BOPP Material is durable and will conform to unique shapes, including squeeze-out applications. Permanent adhesive is a water based, acrylic compound that will stick firmly through different climates and temperatures between -10F and 180F. Looking for a custom label size? No problem! A custom dieline is emailed to you once you place your order.
