Tetra Pak says all of the packages it produces in Brazil are now using bio-based low-density polyethylene (LDPE).
Combined with paperboard, the use of bio-based LDPE made from sugar cane increases the content of materials from renewable sources to as much as 82% in aTetra Brik Aseptic 1000 ml Base package.
In February 2014, Coca-Cola Brazil used the new packages for its Del Valle juice beverages, previously sold in regular cartons.
Following that success, the pilot is now being extended to include all 150 customers of Tetra Pak Brazil, which is more than 13 billion packs every year.
Produced by biopolymer producer Braskem, the bio-based LDPE used in Tetra Pak cartons has the same physical and chemical properties as the traditional fossil-fuel derived polyethylene.
No modification of the machine is needed for customers to switch to the new packaging materials.
Tetra Pak has initially prioritized the Brazilian market but intends to expand the offer to more markets in future.
