A proprietary combination of a specialty HDPE and a high-gloss color masterbatch is said to yield PET-like gloss in molded packaging for personal care, cosmetics, and food markets. New POP High Gloss Colors from Ampacet Corp., Tarrytown, N.Y., are designed to enhance the gloss of HDPE. When combined with a particular HDPE resin, the POP masterbatch has been shown to boost gloss more than 200% over that of standard HDPE. This reportedly allows production of opaque HDPE containers that can replace some PET bottles while providing signifi cant cost and processing advantages. POP colorants also allow packagers to add special effects that are hard to gain in high-gloss PET packaging. Compared with other products that boost HDPE gloss, POP colors reportedly provide greater stiffness and better melt strength, allowing for the use of high-gloss HDPE in monolayer bottles and as the skin in multilayer bottles. Other high-gloss HDPE compounds lack suffi cient parison strength for monolayer bottles and so are only used in outer layers, according to Ampacet. The POP masterbatch is also said to reduce or eliminate melt fracture or excessive parison hang time and to aid column crush strength. Low tackiness of HDPE containing POP colors is said to virtually eliminate demolding problems and downstream handling issues like scuffi ng and conveying hang-ups. POP colors reportedly also confer higher HDT, so packaging is less susceptible to deformation when exposed to higher storage temperatures. FDA-approved for food contact, POP colorants incorporate Ampacet's SmartColor Process technology, which is said to make for easier purging during color changeovers.
