Anti-blocking Masterbatch for Super Transparent Crystal BOPP film ABPP902HT
ABPP902HT uses same sized spherical particles with super high transparency as the anti-blocking agent, and PP with very low haze as the basic resin. The refraction coefficient of anti-blocking agent is similar to PP. All above characteristics can help to minimize the anti-blocking agent’s effect on haze to the greatest extent, giving the film with extremely low haze and high gloss.

★ Base resin’s effect on film haze is not considered.
★ Excellent optical property: high light transmittance, high gloss, ultra low haze.
★ Good anti-blocking performance
★ Suitable for crystal film and BOPP film with ultra-low haze.
★ To produce super transparent film with haze lower than 0.1, it requires proper raw material and techniques.
