Anti-Block Masterbatches are functional additives designed to prevent
sticking or blocking between plastic film layers during processing,
storage, and handling. By introducing micro-scale surface roughness, these
masterbatches improve sliding, unwind, and stacking properties
of films without affecting transparency or mechanical performance. They are
essential for high-speed extrusion, packaging, and industrial film
applications.
Physical & Chemical Properties
Active
Ingredients: Mineral-based fillers, silica, or polymeric anti-block
agents.
Carrier
Resin: PE, PP, PET or universal carriers compatible with target
polymers.
Appearance:
Free-flowing white or translucent granules.
Effect
on Polymer: Reduces interlayer adhesion, avoids film sticking, and
enhances surface slip.
Thermal
Stability: Suitable for extrusion and molding temperatures up to 300
°C.
Durability:
Long-lasting anti-block effect without affecting film clarity or strength.
Applications
Packaging
Films: Food, industrial, and consumer packaging films.
Agricultural
Films: Mulch films, greenhouse covers, and irrigation films.
Industrial
Liners & Sheets: Pallet covers, protective sheets, and laminates.
Textile
& Nonwoven Films: Woven and nonwoven bags, wraps, and hygiene
products.
High-Speed
Processing Films: Any application requiring smooth unwinding and
stacking.
Processing Techniques
Film
Extrusion (Blown & Cast Films) – primary application to prevent
blocking in packaging and industrial films.
Sheet
Extrusion & Thermoforming – trays, panels, and laminated sheets.
Co-Extrusion
– multilayer films with anti-block functionality in selected layers.
Injection
& Blow Molding – surfaces where layer sticking may be an issue.
Sustainability
Reduces
film wastage caused by sticking, tearing, or processing defects.
Compatible
with recyclable polymers, supporting circular economy initiatives.
Non-toxic
and eco-friendly grades suitable for food-contact and consumer
applications.
Enhances
efficiency and reduces energy consumption by improving film handling
and processing.
