Precision Color Masterbatch for Food Packaging Caps
In cap production, the stability of color masterbatch directly impacts finished product quality and efficiency. We focus on solving issues such as black spots, mold deposits, and surface defects caused by poor heat resistance or uneven dispersion of masterbatch. This ensures stable, continuous production for various products—from tamper-evident caps to milk powder lids—significantly reducing defect rates.
- Premium Aesthetic Needs | Provides matte, velvet, and other special textures, achieving precise color matching with optional anti-counterfeiting features
- Efficiency and Cost Optimization | Ensures smooth demolding and batch consistency, delivering optimal cost control and continuous production under compliance
- Expertise in 10+ cap production processes
- Adaptable to global market demands
- Targeted functional additives available
Durable Color Masterbatch for Plastic Handles
Plastic handles endure constant bending, hanging, and repeated use, placing high demands on the mechanical performance of the color masterbatch. Through scientific formulation design, we prioritize material durability and safety while maintaining excellent color performance, delivering solutions that balance aesthetics and reliability for a wide range of handle applications.
Core Capabilities
- Fatigue‑Resistant｜No cracking under long‑term bending and hanging.
- Balanced Stiffness & Flexibility｜Combines shape retention with smooth handling.
- Process Compatibility｜Adapts to various plastic substrates and molding methods.
- Color Durability｜Resists stress‑induced spotting or fading.
Scenario‑Based Solutions
- High‑Load Applications (e.g., logistics packaging)｜Enhanced fatigue and impact resistance.
- Lightweight Designs (e.g., retail packaging)｜Optimized flexibility and tactile comfort.
- Outdoor Use Demands｜UV resistance and weatherability features.
Foundation of Quality:
Double Assurance, Laying a Reliable Groundwork
Through our independently developed functional additive system, we accurately regulate the opening torque of bottle caps. We are committed to achieving the optimal balance between sealing reliability (meeting pressure standards such as 350 kPa/200 kPa) and opening comfort, thereby enhancing the end‑user experience while supporting the use of sustainable materials.
Core Technology Assurance
Precision Torque Control
We have established an ISO 9001 quality management system that covers the entire process from raw materials to finished products. This system ensures that our masterbatch products not only comply with stringent global food‑contact regulations (FDA, EU, etc.) but also deliver high reliability in color consistency, dimensional stability, and safety for every production batch.
