Amcor Rigid Plastics has won the WorldStar 2016 Packaging Award for the development of an ultra-lightweight, hot-fill polyethylene terephthalate (PET) container designed exclusively for PepsiCo-Lipton’s tea drink brand in Central America.

The WorldStar Packaging Competition is one of the major events of the World Packaging Organization (WPO) and is the pre-eminent international award in packaging. Winners for the 2016 awards were selected by representatives from 19 packaging associations - members of WPO - who judged 293 packaging entries from 35 countries.

The 500 ml package weighs only 22 grams and utilizes a 33 mm finish that features a 50 % reduction in material over a traditional 38 mm finish. The sleek leaf body panels aid in the vacuum while providing visual movement and a comfortable gripping surface for the consumer. Additional benefits of this package are substantial ecological savings, lower operational costs, and a significantly reduced carbon footprint. It sets a new benchmark for heat-set PET containers, enabling manufacturers to achieve aseptic filling packaging weights without the prohibitive investment, while offering a more eco-friendly option.

The PepsiCo-Lipton container is an extension of Amcor’s ultra-lightweight technology which was previously employed in a new sports beverage package in Latin America. Achieving the lightweight properties which could withstand intense vacuum absorption was a big challenge. Amcor applied its vacuum absorbing base (VAB) technology to the base and ERGO technology to the body. The VAB base is a light weighted diaphragm-like structure that aids in the cooling process by helping to absorb vacuum.

Along with the ultra-lightweight container, Amcor and Bericap, in cooperation with PepsiCo, developed the industry’s lightest 33mm tamper-evident finish/closure for hot fill, weighing in at just 3.7 grams. Amcor believes the unique finish will become a new standard for hot-fill bottles due to the 7.9 gram reduction in weight compared to the standard 38mm ALCOA. This new finish led to the creation of a Bericap closure with a built-in seal that eliminates rubber liners or induction seal foils, thus reducing overall materials use. The Bericap closure is made of high-density polyethylene (HDPE) instead of polypropylene (PP) like the previous caps. HDPE is more widely accepted than PP in recycle streams and the absence of any other barrier materials such as ethylene-vinyl acetate (EVA) or paper/foil increases recyclability.
