Description

Agricultural Film Filler Masterbatch

Agricultural film filler masterbatch (formulated with ultrafine Na2SO4, BaSO4, or surface-modified CaCO3) is engineered specifically for agricultural covering and cultivation protection. It is widely used in mulch films, greenhouse films, silage stretch films, and nursery plant bags.

Features:

• Substantial Cost Savings: Replaces prime virgin PE resin at high loading rates without sacrificing physical film integrity, significantly reducing total production costs per square meter.

• Balanced Light Transmission & Diffusion: Refractive index closely matches polyolefin resins, preserving sunlight transmission for greenhouse films while enhancing light diffusion to minimize crop scorching.

• Superior Tensile & Puncture Resistance: Ultrafine particle size distribution ensures homogeneous dispersion, boosting tear resistance and puncture durability during field installation and automated silage wrapping.

• Excellent UV & Additive Compatibility: High-purity, chemically stable carrier formulation works seamlessly with UV stabilizers, antioxidants, and optical brighteners without shortening outdoor service life.

• High Processing Stability & Bubble Control: Offers consistent melt flow properties and rapid thermal conductivity, preventing die build-up, screen clogging, and bubble instability in wide-width, down-gauged film extrusion.
