Na₂SO₄ Masterbatch for PP and PE Film
Product Introduction
Sodium Sulfate Filler Masterbatch is a high-quality additive developed to enhance film transparency and cut down resin usage. It helps manufacturers lower production costs while keeping product performance stable. The masterbatch is made by mixing polyethylene resin with ultra-fine sodium sulfate powder through advanced extrusion and granulation. The result is a product with good dispersion, steady heat resistance, and clear optical effect.
The Filler masterbatch is specially designed for PP and PE film. It provides a cost-effective and eco-friendly choice for extrusion, sheet forming, and injection molding processes.
Why Sodium Sulfate Masterbatch Is Perfect for Blown Film
Na2SO4 masterbatch offers superior compatibility with PE and PP resins, ensuring high transparency and mechanical balance. Itis fine particle size (1500-6000 mesh) allows even distribution, minimizing haze and maintaining film clarity.
When used in blown film applications, it provides:
💡 Minimal impact on transparency—adding the appropriate ratio does not affect product clarity.
⚙️ Smooth extrusion and stable melt flow make it suitable for multi-layer co-extrusion lines.
🧊 Enhances cooling and bubble stability, reducing film breakage during production.
💰 Reduces raw material costs and can improve strength and performance to a certain extent.
Common applications include shopping bags, food packaging films, garbage bags, agricultural films, and construction membranes.
