Closure molder improves color distribution and saves $100,000 annually

• Patented pelletized colorant ensures well-dispersed color
• Significant cost reduction in cap and closures applications
• Case studies

Molding caps and closures to meet customers’ demands is challenging. In addition, major brands demand that the color of the product must be an exact match every time. Continually meeting such exacting brand retail shelf expectations is nearly impossible. For example, one closure manufacturer for large brands needed to lower overall cost while still maintaining a consistent color for every part. After exploring several options, the manufacturer selected G2 from Carolina Color.

Patented pelletized colorant ensures well-dispersed color

In 2008, Carolina Color patented G2, a completely new kind of product in which pigments and additives are highly loaded, well dispersed, and effectively distributed in both large and small parts. Most packaging manufacturers see up to 30% cost-to-color reduction, along with letdown rates matching or exceeding liquid colors.
