Additive Masterbatch
Goldmine’s Additive Masterbatch range is engineered to enhance the functional, mechanical and processing characteristics of plastics
From slip modification and anti-blocking to antioxidant protection, whitening and toughness enhancement — each additive is designed to solve specific polymer challenges while improving productivity and final product quality.
Our additive portfolio supports PE, PP, PS, ABS, PET and recycled polymer applications across packaging, moulding, film extrusion, sheet lines and industrial manufacturing.
Why Additive Masterbatch?
Polymers rarely perform optimally on their own. During processing, cooling, printing, transporting or long-term use, plastics face challenges such as friction, blocking, thermal degradation, yellowing, brittleness, and structural instability.
Additive Masterbatch solves these issues by providing:
- Smoother processing
- Better surface quality
- Improved mechanical performance
- Cleaner film handling
- Thermal stability
- Enhanced visual appearance
Each masterbatch is designed to integrate seamlessly with your existing resin system while delivering measurable performance advantages.
Our Additive Masterbatch Portfolio
Slip Masterbatch
Controlled COF • Smooth Film Movement • Packaging Efficiency
Reduces surface friction on PE films to ensure smooth winding, unwinding, slitting and pouching operations. Essential for printing and lamination lines.
Anti-Block Masterbatch
Clean Roll Release • Better Handling • Balanced Haze
Introduces controlled micro-roughness to prevent film layers from sticking during cooling or winding, improving roll quality and machine uptime.
Anti-Oxidant Masterbatch
Heat Stability • Melt Protection • Oxidation Control
Protects polymers from thermal degradation, yellowing, brittleness and gel formation during high-temperature processing or recycling cycles.
Optical Brightener Masterbatch
Brilliant Whiteness • High Gloss • Yellow-Index Correction
Enhances whiteness and surface brightness with blue-violet fluorescence. Ideal for improving appearance in films, moulded products and recycled polymers.
Modifier Masterbatch
Impact Strength • Flexibility • Stiffness Enhancement
Improves toughness, flexibility or rigidity depending on grade. Works across films, moulding, profiles, sheets and recycled compounds.

FAQ
Yes — custom multifunctional additive blends can be formulated.
Yes, several additive categories are available in food-contact compliant versions.
Absolutely — antioxidants, modifiers and brighteners significantly upgrade recycled material quality.
Depends on the additive. Anti-block/fillers may add light haze; slip and brighteners usually do not.
