HDPE Cap Color Solutions

The client, a leading beverage packaging manufacturer, needed to color-match more than 300 distinct HDPE cap designs — each carrying its own brand-specific shade. Every cap had to be food-contact compliant and visually identical across multiple production facilities, turning a routine coloring task into a large-scale color-management challenge.

• Over 300 unique HDPE cap designs requiring individual color matching
• Strict batch-to-batch color consistency with Delta E below 1.0
• FDA food-contact compliance for every pigment and additive
• Color must remain stable through high-speed injection molding
• Fast turnaround needed to support frequent new product launches

MHK Color deployed a dedicated color-matching team and applied our 30,000+ formulation database to streamline the entire workflow, from initial sample to full production.

• Matched every cap design to the client's RAL or Pantone reference using FDA-compliant pigments
• Selected a PE carrier resin optimized for HDPE dispersion and melt-flow stability
• Provided free physical samples within 24 hours for rapid customer approval
• Implemented spectrophotometric verification to lock each shade to a reproducible formula
• Supplied masterbatches in production-ready pellet form for direct dosing

All 300+ color formulations were delivered within six months, with no color-related production delays. The project delivered measurable quality and cost improvements across the client's entire cap portfolio.

• Batch consistency maintained at Delta E below 0.8 across all production runs
• 15% reduction in color-related rejects and rework
• Zero FDA compliance issues across the full 300+ formulation set
• A reusable color library that lets the client order repeat shades in days, not weeks
