Properties & Characteristics |
Chemical Composition |
- Resin (e.g., modified PP resin, chlorinated PP, acrylic resin) |
- Pigments |
- Solvents (esters, ketones, or benzene-based) |
- Additives (adhesion promoters, dispersants, etc.) |
Polarity |
Non-polar, designed to bond with non-polar PP surfaces (requires pre-treatment like corona discharge) |
Adhesion |
Strong adherence to PP after surface pre-treatment (tested via cross-cut adhesion test) |
Viscosity |
Moderate viscosity, adjustable for different printing processes (gravure, flexo, screen printing) |
Drying Mechanism |
- Volatile drying (solvent evaporation) |
- Cross-linking (UV or heat curing for high-performance applications) |
Film Properties |
- High gloss or matte finish options |
Scratch-resistant and abrasion-resistant |
- Moderate temperature resistance (short-term ≤100°C) |
Chemical Resistance |
Resistant to oils, greases, and common solvents (e.g., alcohol, gasoline) |
Environmental Features |
- Traditional types may contain VOCs; low-VOC or water-based alternatives available |
- Food-grade compliance options (FDA, GB 4806.10) |
Printing Compatibility |
- Suitable for BOPP films, PP sheets, and injection-molded PP products |
- Requires surface pre-treatment (corona/flame treatment) |
Color Performance |
- High color coverage and opacity |
- Good lightfastness (with UV stabilizers for outdoor use) |
Typical Applications |
- Food packaging (bags, labels), industrial containers, advertising banners, consumer product labeling |
