Opti-Block Talc 8

This talc is designed for use in films for food, packaging and bag applications such as: food packaging, stretch and shrink films for packaging, grocery and trash bags, and industrial films. This talc has excellent antiblocking efficiency and provides high clarity with low haze. It exhibits low interactions with stabilizers, slip agents, and processing aids. This allows for film formulations with low coefficient of friction, excellent stability and good color. The ease of dispersion makes it suitable for use via direct addition, as a masterbatch or in high active concentrates.

Formulation recommendations: This talc is typically utilized in polyolefin films, but can also be used in PVC films. Depending on the formulation and application requirements, typical levels of antiblock range from 3000-7000 ppm. For optimal performance, we recommend using antiblock talc in combination with slip agents.
