The 4090 strapping tape has a strong tensilized polypropylene backing with a rubber resin adhesive. The adhesive has good initial tack and high shear resistance. Properly applied the tape shrinks around loads and holds them tightly. Impact strength allows give-and-take without snapping. The tesa 4090 is best used for palletizing and unitizing corrugated and paper board boxes and non-critical bundling applications.
