Fresh milk in clear PCR/PET bottles for the Argentinian market

Amcor has broken new ground in the Argentine dairy market developing the first fresh milk bottle made of transparent post-consumer recycled (PCR) PET resin. The custom-designed 1l container for leading dairy maker Mastellone Hnos, Buenos Aires, is intended to support the positioning of the La Serenísima Original milk brand as a natural product while also delivering optimum shelf life and increased sustainability benefits. 

Latin American dairy companies are increasingly using clear PET bottles to showcase freshness and premium quality. The cold-fill bottle contains 20% PCR content and is designed to drive consumers from aseptic packages to the chilled section of the grocery store. The breakthrough bottle follows the October 2019 launch of Mastellone’s shelf-stable, ultra-high temperature (UHT) white milk in aseptic, white-coloured PET bottles also from Amcor.  

“In a market that has remained stagnant for several years, we’ve broken the rules by developing an entirely new format offering for fresh milk,” said Martin Darmandrail, Amcor’s Specialty Containers Director (Argentina). “We’ve shaken things up with a unique fresh milk package with the durability, freshness, performance, and sustainability benefits of PET.”  

The container includes a 38mm finish and a HDPE screw cap from Bericap North America (a joint venture between Amcor and the Bericap Group). A key technical challenge was limiting light exposure and preventing damage to the product. To preserve the contents, a special barrier was developed to help extend shelf life.  

In Argentina, the new fresh milk product will be available in select metropolitan areas with broader distribution later.
