Highly crystalline structure enabling rapid melt crystallization and excellent storage stability.
Low melt viscosity at processing temperatures, facilitating smooth extrusion and uniform film formation.
Outstanding thermal stability with minimal degradation up to 240 °C under inert atmosphere.
Excellent compatibility with aliphatic polyesters and biodegradable polymer blends.
Consistent batch-to-batch reproducibility meeting ISO 9001-certified manufacturing standards.
Biaxially oriented polyester (BOPE) films for high-barrier flexible packaging.
Heat-sealable top layers in multilayer food packaging laminates.
Crystallinity-enhancing modifier in PLA/PBAT-based compostable films.
Base resin for engineered monofilaments requiring dimensional stability and stiffness.
Carrier resin in masterbatch formulations for color and additive dispersion.
