Most of the beverages bottled on Adelholzeners aseptic line are all in monolayer PET containers. But one product called Active O2 is an oxygenated beverage that requires a barrier layer in the PET bottle to properly maintain the oxygenation. So for this container the firm buys coinjection-molded preforms with a PET/nylon/PET structure. The bottles stretch/blow-molded from these preforms provide Active O2 with a 9-mo shelf life. Available in both 0.5- and 0.75-L sizes Active O2 is decorated with a film label rather than the paper label used on the other products that run through the line. Still the same Krones labeler handles the hot-glue label application. The distinctive Active O2 packaging says president of sales and marketing Stefan Hoechter has played a key role in making the product a huge success since its debut almost a year ago. With Active O2 weve become a national brand says Hoechter. Thats highly unusual in Germany where most beverages are regional not national. Its even more unusual to have achieved it over such a short period of time.
