Swedish packaging firm Tetra Pak has launched a new bio-based cap for gable top carton packages.
The new cap is made from high density polyethylene (HDPE) derived from sugar cane.
The company says that the launch of the bio-based version of TwistCap OSO 34 is a key step towards the development of fully renewable packages. Around 80% of the material in its one-litre Tetra Rex brand carton is wood-made paperboard. The new bio-based cap increases the content of renewable material in the package by 4%.
The year 2013 saw the sale of about 1.1 billion bio-caps globally, representing a rise of over 80% compared to 2012.
Tetra Pak product director Christina Chester said that Finland-based dairy products manufacturer Valio is the first firm that used the new version of the bio-based cap for its products.
"We are glad that customers see value in our efforts to help them boost their environmental profile," Chester added.
