Intertape 530 Utility-Grade Flatback Packaging Tape is a pressure sensitive, moisture resistant Kraft flatback tape coated with an aggressive blend natural/synthetic rubber adhesive designed to offer a positive, attractive seal and excellent adhesion to minimize carton sealing failures and prevent pilferage. Performs well under a wide range of temperature and humidity conditions. Intertape 530 (previously called Anchor 530) is designed for use in applications where reduced weight can provide packaging material savings. Complies with Postal Regulation for Uninsured Packages. Application uses include carton sealing, packaging, silk screening, picture framing, beaming/leasing, splicing, and tabbing. Product is not repulpable. *** If product size is on sale and mentions that it comes on a non-branded white core means our converter had an overstock jumbo roll available so rolls get slit from that. When rolls are slit from a jumbo they get wound onto plain white cores, not an Intertape / IPG branded core. If not otherwise specified widths shown in dropdown are in inches. NOTES: Sizes shipped will typically be the tape industry standard metric-cut sizes, i.e. 24mm for each 1 inch of nominal tape width ordered (rolls are approximately 5% narrower than the nominal size). This product's actual size is 48mm x 55m.Technical InformationCore: 3 inch diameterBacking/Carrier: kraft, flatback paperAdhesive: natural / synthetic rubberThickness: 7.2 mils (carrier, adhesive)Adhesion: 60 ounces per inch (to stainless steel test panel) Tensile Strength: 45 pounds per inch (longitudinal) Elongation: 8 %.
