Simplify your packing operations with a proven solution. 3M™ water activated paper tape 6143 is an easy, economical solution to a range of basic carton sealing challenges. We designed this heavy duty, water activated "gummed" adhesive tape to provide a strong seal to a wide variety of corrugated surfaces. 3M™ water activated paper tape 6143, with our high tack, water activated adhesive, ensures your corrugated boxes stay sealed until ready for opening. In tandem with the non-reinforced, heavy duty, 90 lb kraft paper, our high tack water activated adhesive system holds the tape in place throughout shipping, handling and storage. This tape is available in natural kraft color. We recommend 3M™ water activated paper tape 6143 for sealing medium weight packages. When water activated, this tape easily and quickly conforms over carton edges and corners to form secure C-clip and L-clip seals. Our water activated, or "gummed," tape is very effective for sealing corrugated cartons, as the adhesive will bond with the fiberboard material to create a strong durable seal and endure the toughest handling and shipping scenarios. Our tape works well on recycled cartons and non-unitized loads. Its 90 lb paper construction assures reliable performance across a range of environments and applications. Our economical packaging tape meets the needs of numerous industries and general industrial applications such as food, beverage, medical pharmaceutical, paper, print, electronics, shipping and distribution centers. 3M™ also offers semi-automatic application equipment to increase efficiencies and help speed up your packaging needs and carton sealing processes. Application is most easily accomplished at room temperature and once applied, the tape performs well throughout the normal temperature ranges typically encountered by packaged products in shipping and storage environments. 3M™ water activated dispensers and water activated tapes are an easy, economical solution to a wide variety of carton sealing challenges. To create a strong, lasting seal, the moistened adhesive interacts with porous surfaces to form a powerful, secure bond. This tape bond forms a tamper evident seal that shreds if an attempt is made to pull it off before delivery. Normally constructed from paper, our taping system is easy to operate, apply and handle, making it ideal for hand applications. Boxes are securely sealed yet easy to open without cutting tools. 3M™ 7000049629, Heavy Duty, 375 ft Length, 3 in Width, 7.5 mil Thickness, Kraft, 3 in Diameter Core, Gummed Modified Cornstarch Adhesive, Paper Backing, 58 in-lb Tensile Strength, Specifications Met: ASTM D645/D646/D5803/D1922
