E-4833 is a 3 mil white PP (polypropylene) label material designed for tubes, bending blood bags, disinfection and low-temperature operating requirements. The soft, flexible facestock delivers excellent adhesive cohesive strength with strong water- and moisture-resistance, good tensile and tear strength, and excellent low-temperature and physical/chemical stability. A special surface coating raises the material's active surface energy for stronger ink absorption and compatibility with most printing methods.
