Bronco Wine Co. switched the packaging material for its 187-ml. single-serve bottles of wine from glass to lightweight PET bottles from Amcor Rigid Plastics. The adoption of PET was made to improve penetration of its Crane Lake, Red Truck, Coastal Ridge, Hacienda, Harlow Ridge and Forestville brands at retail and on airlines, including Delta Air Lines, United Air Lines and Southwest Airlines, the company says. The bottles utilize barrier-coating technology developed by Germany’s KHS Plasmax GmbH to protect the contents from oxidation and extended shelf-life. Bronco invested in new filling equipment for 187-ml. bottles to be able to expand within the high-growth, single-serving wine market, it says.
