Food processing and packaging solutions provider Tetra Pak has announced that it will use bio-based low-density polyethylene (LDPE) for the carton packages which it produces in Brazil.
Bio-based LDPE is made from sugar cane. In combination with paperboard, the bio-based LDPE will increase the content of renewable materials to as much as 82% in a Tetra Brik Aseptic 1000ml base package.
Coca-Cola Brazil was the first company to use the new packages for its drinks. It previously sold its Del Valle juices in regular cartons.
The pilot is now being extended to include all 150 customers that source from Tetra Pak Brazil, with a total of around 13 billion packs annually.
Tetra Pak marketing and product management vice president Charles Brand said that by further increasing the use of renewable resources, the sustainable future of the packaging industry can be protected, while meeting the global challenge of a growing scarcity of fossil-fuel-based raw materials.
"We are particularly proud to be the first in the industry to use bio-based LDPE in carton packages," Brand added.
"We have set an ambition to develop a 100% renewable package, building from an average of 70% today. This launch is an important step in that direction."
The bio-based LDPE used in Tetra Pak cartons is produced by biopolymers producer Braskem.
