Brown Economy Grade Water Activated Gummed Kraft sealing tape Kraft Paper Tape is naturally a more eco-friendly choice in carton sealing. We start with a renewable paper backing, add interwoven fiberglass threads and finish it off with a water-activated, high-performing corn starch adhesive. Best of all, Eco Enclose Kraft Paper Tape will not only out-perform your plastic tape, but it is actually more affordable per carton seal in comparison to your standard plastic tapes. Plastic tape may require several strips over the same seal to provide the same holding power of just one strip of paper tape.
