From the manufacturer:
Use these tapes for joining the edges of boxes, adding a finishing touch to the edges of boards or hinging album pages. The linen is a favorite for hinging window mats to backboard or attaching art. The very fine linen cloth is flexible yet strong. The neutral pH acrylic adhesive gains strength overnight.
