Tetra Pak launches first bio-based cap for gable top

Tetra Pak has launched the first bio-based opening for gable top packages. Manufactured using high density polyethylene (HDPE) derived from sugar cane, the bio-based version of TwistCap OSO 34 marks another step forward in Tetra Pak’s ambition to make fully renewable packages. In 2013, the company delivered 1.1 billion bio-caps globally, an increase of more than 80% over the previous year.

80% of the material in a one-litre Tetra Rex carton is paperboard, which is made from wood, a renewable resource. By introducing the new bio-based cap, the content of renewable material in the package increases by an additional 4%, helping to further improve the environmental performance of the package without compromising its functionality or recyclability.

“Launches of bio-based caps have been appreciated by customers like Valio, the Finnish dairy who is the first to use the new version of TwistCap OSO 34 for its products,” says Christina Chester, product director at Tetra Pak.

Tetra Pak customers using the standard TwistCap OSO 34 can easily transfer to the bio-based version without the need for any additional investment or modification to their existing filling machines.
