Reinforced Gum Tape:Kraft Tape is made from kraft paper, a durable material known for its strength and resilience. The tape's adhesive is water-activated, forming a strong, lasting bond with the surface it is applied to. This adhesive ensures that the seal is secure and durable, making it ideal for heavy packages and long-term storage. The strength and durability of kraft tape make it resistant to tears and punctures and its strong adhesive visibly shows if the package has been opened or tampered with.Item Specifications:● Color: Kraft● Grade: Industrial● Quantity: 6 Rolls● Reinforced: Yes● Brand: Shield Tape● Country Of Origin: USA● Water-Activated Adhesive: Yes● Total Thickness: 5.0 to 6.0 Mil● Tape Dimensions (W x L): 72mm x 500'● Tensile strength [MD]: 40-45 lbs./in [ASTM D-828]● Tensile strength [CD]: 15-20 lbs./in [ASTM D-828]● Backing [Top]: 20.0#/3000 Sq.
