Our water based acrylic carton sealing tape line is made with a special high-shear adhesive, developed specifically for Primetac in 2005 to meet our rigorous specifications. Higher shear values mean greater holding power on boxes. Our 400 series acrylic tapes conform to FDA requirements for indirect food packaging (CFR, Title 21, Subpart B, 175.105). These products can make ideal cold temperature, refrigerator, and freezer tapes.
