Deep Technical Insights
Repol SR20NC features a specialized clarifier additive formulation that delivers crystal-clear transparency rivaling glass, with minimal haze and excellent gloss. The low melt flow rate (1.9 g/10 min) provides superior melt strength during blow molding, preventing parison sag and enabling production of thin-walled containers with uniform wall thickness distribution. The random copolymer architecture—with ethylene monomers randomly distributed throughout the propylene backbone—disrupts crystallinity, enhancing impact resistance, stress-crack resistance, and optical properties while maintaining excellent chemical resistance. All additives comply with FDA and IS standards, ensuring safety for food contact and pharmaceutical applications.
Applications and Industry Uses
High-Clarity Transparent Packaging
SR20NC is the benchmark choice for manufacturing crystal-clear bottles and containers for food, beverages, dairy products, and condiments. Its exceptional clarity and gloss finish enhance product visibility and premium shelf appeal, while its impact resistance ensures durability during transportation and consumer handling.
Pharmaceutical and Medical Containers
The grade’s food-contact compliance (IS 10910, FDA CFR 177.1520) and low extractables profile make it ideal for pharmaceutical bottles, medical-grade containers, and laboratory storage vessels. Its dimensional stability and chemical resistance ensure product integrity throughout shelf life.
Personal Care and Cosmetic Packaging
SR20NC’s superior clarity and aesthetic appeal position it as the preferred material for shampoo bottles, liquid soap containers, lotion bottles, and cosmetic packaging. The grade’s excellent processability enables complex bottle geometries with consistent wall thickness.
Stationery and Ball Pen Refills
The grade’s dimensional stability, clarity, and ink compatibility make it the industry standard for transparent ball pen refills, office organizers, and stationery products requiring precision and visual appeal.
Sheet Extrusion and Thermoformed Products
SR20NC’s process stability supports production of high-clarity thermoformed sheets, protective packaging inserts, display packaging, and rigid transparent containers for food service and retail applications.
