PMMA Microparticles

PMMA-based microparticles for anti-blocking performance in BOPP films.
Delivering low friction, optical compatibility, and food-contact compliance for global packaging applications.

Reliable Anti-Blocking Solution for BOPP Film Production

The Epostar MV series are PMMA-based organic microparticles designed as anti-blocking additives for biaxially oriented polypropylene (BOPP) films. With spherical particle sizes ranging from 4–10 µm, they can be optimally matched to film thickness, ensuring effective slip control and surface functionality. Their refractive index closely matches that of BOPP, maintaining optical clarity while reducing the coefficient of friction.

The Epostar MV series is fully compliant with major international food-contact regulations, making them suitable for global packaging applications requiring safety and performance.

NAGASE supplies PMMA microparticles worldwide, providing consistent quality, regulatory compliance, and technical support for film manufacturers.
