Polybond RST 80 gsm is a unique Surface Treated Reinforced top web solution made of a 80 gsm fiber
matrix saturated with a selection of water based, synthetic and soft resins to dramatically enhance its
mechanical behavior of the material. The chemical treatment added to the reinforced matrix allows
excellent sealing performance, high reactivity, while persuing optimized breathability for efficient EO
sterilization process. With a renewable resources content of more than 70% for better environmental
performance, Polybond RST 80 gsm is designed to seal to flexible formable film grades such as PA/
PE or PP/PA/PE or PP/PE substrates. Polybond RST 80 gsm is compatible with EO and Irradiation
sterilization processes.


Polybond RST 80 gsm is a unique solution to reduce the cost of your most demanding packaging
designs: high seal strength, easy runnability, clean peel opening. Surface treated webs run in a 20°C
operating window depending on packaging lines. Polybond RST 80 gsm is particularly adapted to
tubings, IV sets, catheters, small drapes and gowns materials as well as procedure kits packed in
flexible packaging.
