METHOD OF MANUFACTURING A PREFORM

摘要

One or more colorants are infused into thermoplastic materials in a randomized pattern to create a unique visual effect in a plastic preform or container. The visual effect may be similar to that of a drop of dye diffusing in water and forming a ribbon pattern. In some embodiments, a desired infusion effect may be achieved by generating inconsistent loading of a colorant-containing intermediate layer to achieve ribbons or swirls of color throughout the preform or a portion thereof.
