Foil backed pavement tape is a simple product consisting of 5 basic layers, beads, paint, aluminum, scrim, and adhesive. These layers are combined or laminated together to form the rolls of pavement tape that you see being used in construction zones for road striping, and in warehouses for delineation. The process of creating pavement tape is actually quite simple.
The wide roll of coated aluminum is then pulled on rollers over statically charged microscopic glass beads. The static charge causes the beads to attach themselves to the still wet acrylic coating as it passes over. This method is used to create an even coating of beads.
