Smoothness Masterbatch (Opening Agent Masterbatch)
Anti-blocking: Prevents film layers from adhering due to static or pressure.
Slip enhancement: Lowers surface friction for high-speed packaging or cutting.
Surface protection: Reduces scratches and maintains film clarity/printability.
1. Basic Concept
Anti-blocking masterbatch is a functional plastic additive primarily used to improve the opening performance of plastic films (e.g., PE, PP, BOPP), preventing film layers from sticking together during winding, stacking, or storage. Its core functions are to reduce the coefficient of friction (COF) on the film surface and create micro-roughness to minimize direct contact between layers.
2. Key Components
Component | Mechanism | Common Materials |
Anti-blocking agent | Forms micro-protrusions on the film surface to reduce contact area. | Silica (SiO₂), diatomite, ceramic microspheres |
Slip agent | Migrates to the surface to form a lubricating layer. | Oleamide, erucamide (food-grade), EBS (ethylene bis-stearamide) |
Carrier resin | Ensures compatibility with the base polymer. | LDPE, LLDPE, PP (selected based on film material) |
Additives | Improves dispersion, thermal stability, etc. | Antioxidants, dispersants (e.g., polyethylene wax) |
3. Applications
Packaging films: Food bags, courier bags, stretch films (target COF: 0.2–0.4).
Agricultural films: Mulch films, greenhouse films (requires weather-resistant grades).
Industrial films: Protective films, release films (high anti-blocking demand).
Medical films: IV bags, pharmaceutical packaging (requires FDA-compliant slip agents).
