HMEL PP Polysure R03RR1
HMEL PP Polysure R03RR1 is a polypropylene homopolymer tape-extrusion grade produced by HMEL using Spheripol-II technology for raffia, monofilament, and woven-sack applications. It features extremely low water-carry-over, high tenacity, and excellent processability for high-speed tape and monofilament lines.
R03RR1 vs R03RR and other HMEL PP homopolymer grades
R03RR1 (Spheripol-II) is tailored for high-speed raffia/tape extrusion and monofilament, while R03RR (Novolen) targets similar applications with alternate technology. Both are part of HMEL’s woven-sack/tape PP range.

Applications & Industry Use Cases
Raffia Tape & Woven-Sack Applications
Polysure R03RR1 is engineered for high-speed tape extrusion and woven-sack manufacturing, yielding strong, ductile tapes for food-grade and industrial sacks.
Monofilaments, Ropes, Strapping & Leno Bags
The grade delivers stable draw-down, low breakage, and high tenacity for monofilament yarns, ropes, strapping, and mesh-style packaging.
Thermoforming and Structural Webbing Uses
R03RR1 supports thermoformed bands, straps, and webbing applications needing high stiffness and ductility.
Performance Advantages of Polysure R03RR1
R03RR1 features extremely low water-carry-over, minimizing bubbles and line instability. Its high stiffness and ≈9% elongation balance enable tear-resistant tapes and ropes, while its processability ensures smooth, stable production on modern raffia lines.
Comparison to Other PP Tape / Raffia Grades in India
- Polysure R03RR1 (HMEL): Spheripol-II, 3.4–3.5 MFI, tape/raffia/monofilament
- R03RR (HMEL): Novolen, similar applications, alternate tech
- IOCL 1030RG / AS030N (Propel): Homopolymer, ~3.3 MFI, tape/raffia
- Reliance H030SG (Repol): Homopolymer, raffia grade
- HR003 (MRPL): Tape/raffia, low water-carry-over
Key Differentiators: R03RR1 is a premium choice for woven-sack, tape, and monofilament lines needing low water-carry-over and high tenacity, with Spheripol-II technology for advanced processability.
