Film Anti-blocking Silica

Product Specification

Feature

Targeted anti‑blocking function for plastic films: Creates uniform micro‑protrusions on film surface to decrease direct contact area between stacked film layers, efficiently solves blocking problem caused by pressure, high temperature and long‑time storage during winding and stacking. Low haze & high optical performance: Optimized particle morphology and narrow particle‑size distribution, brings minimum rise in haze; preserves original transparency, gloss and visual appearance of finished films. Outstanding resin dispersibility: Low agglomeration characteristic, disperses homogenously inside polyolefin resin during masterbatch compounding and extrusion. Avoids fish‑eyes, pinholes, white spots and other surface defects on film. Excellent thermal stability: Tolerates high temperature of extrusion, casting and film stretching processes. No decomposition, yellowing or volatile by‑products; adapts to high‑speed film production lines. Balanced synergistic effect with slip agents: Perfectly cooperates with slip additives to achieve ideal balance of anti‑blocking and slip performance; stabilizes friction coefficient for film winding, slitting and converting operations. Minimal influence on post‑processing performance: Does not impair subsequent printing, metallizing, coating and laminating properties of films; keeps good surface tension for further processing. High purity with strict impurity control: Low coarse particles, heavy metals and volatile content. Available grades meet food contact requirements for food packaging film applications. Broad film‑type compatibility: Suitable for BOPP, CPP, PE, PET and other cast & biaxially oriented plastic films; works for food packaging, industrial packaging, printing and composite film grades. Stable batch‑to‑batch consistency: Tight control over particle size, oil absorption and moisture; ensures stable masterbatch performance and steady film quality for continuous mass production. Complete technical & compliance support: COA, MSDS, food‑contact certification and application guidance are available, supporting customer formula debugging and production scale‑up.
