The award, which comes one month after winning the ‘Best lightweighting initiative’ category at the InnoBev Sustainability Awards, recognised the ultralight 5-litre container, created to meet the increasing demand of bottling companies to improve their environmental performance in larger containers.
The reduction in raw material, the consequent reduction in buying costs and its resulting positive environmental impact, the use of 50% recycled PET, its good mechanical performances and the high final quality of the bottle are the reasons why the jury chose the 5 LW.
The 60.4g 5LW allows a saving of 17.6g of PET in every bottle, which is almost 22.5% when compared to the other bottles in the market.
This extreme lightweighting has been made possible through an accurate design combination of preform and bottle, which led to a perfect material distribution on the most structural parts of the bottle, avoiding overstretching. The ribs ensure high mechanical performances and at the same time they offer rigidity, avoiding implosion while pouring.
The study of the preform and its streamlining allow the use of resins with lower mechanical performances when compared with standard PET (that is to say, recycled and similar materials). 5LW was blown with 50% recycled PET and supplied by Plastipak. 5LW was created thanks to the collaboration between PET Engineering, Novapet and Side.
