Teknor Color has adapted its PETek™ PET colorant technology, previously introduced for health and beauty aid packaging, to meet the much lower loadings typical in beverage bottle manufacture.

As a result PET beverage bottles can now be created using the tiny color-concentrated PETek™ beads said to provide a more sparkling and vibrant look while reducing scrap rates and color loadings. The concentrates differ from pellets liquid colorants and wax-based solids conventionally used in PET packaging because of their unique size shape and composition. The micro-beads in dias as small as 0.05” disperse color through a polymer system compatible with PET. The tiny bead size allows color to disperse efficiently providing sparkling clear and opaque containers with reduced swirl haze and other defects.
