Color migration usually happens when the pigments aren’t fully compatible with the resin or the product itself. To prevent this, you’ll want to use pigments specifically rated for low migration. If you need help finding the right match, our Colormate® masterbatch or pigment can be customized for your specific resin and application to ensure the color stays locked in place.
It looks like your product needs better protection against light and environmental elements. The best approach is to match the pigment’s resistance level to the product’s actual environment, whether that’s long-term indoor lighting (high lightfastness) or harsh outdoor weather (weather condition). If you’d like, our team can help you look at your product’s application and customize a Colormate® masterbatch that will keep your colors vibrant for much longer.
Food contact plastics are highly regulated, and compliance depends entirely on where your product is sold, such as US FDA (21 CFR), Europe (EU 10/2011), or regional standards like PNS 1104. To make this easier, our team can customize your color masterbatches to meet these exact global guidelines. Just let us know your target markets, and we’ll ensure the right compliant pigments are formulated for your products.
