With producers and consumers alike becoming ever-more focused on climate change and the need for greater sustainability, food packaging has had to evolve to meet this growing demand. Tetra Rex has always been a pioneer in this regard, and continues to deliver – from using plant-based polymers derived from sugarcane to greater efficiency when it comes to transportation and storage, here’s how Tetra Rex delivers on the need for sustainability.
Tetra Rex is made of fully renewable material – its three layers consist of paperboard sandwiched between an internal and external layer of polymers derived from sugarcane, while the cap and neck are made of plant-based HDPE (high-density polyethylene) and LDPE (low-density polyethylene).
Plant-based HDPE (high-density polyethylene) and LDPE (low-density polyethylene) for the cap, neck, and coating come from a non-food substance derived from sugarcane. They further lower a package’s carbon footprint1 and increase its renewable content, but have the same consumer functionality and recyclability as standard caps.
167% less CO2 compared to equivalent fossil-based cap
Sugarcane has numerous benefits. It breaks fossil dependency and reduces climate impact, and as a crop with a high yield, less land is needed. We also don’t source sugarcane from high-value land, meaning there is no impact on food production.
A Tetra Rex package made of plant-based packaging material with a plant-based opening has a 34% lower CO2 footprint2 compared to a standard fossil-based Tetra Rex, a reduction that’s verified by the Carbon Trust.

Using physically segregated bioplastics – physical segregation between fossil and renewable plastics production – allows you to make greater certifiable claims about your package, such as measurable plant-based content and CO2 footprint reduction.
The Bonsucro on-pack label certifies the responsible sourcing of sugarcane, while the FSC™ on-pack label certifies that the paperboard comes from well-managed forests and other controlled sources.

Tetra Pak’s FSC license code is FSC™ C014047
Braskem is the only commercially viable source for fully renewable plant-based polyethylene. Their sugarcane is grown mainly on degraded pasture land, so it does not compete with food production, and the material is traceable through the entire supply chain – no palm oil or animal fat is added or used anywhere in the process.
This effect consists of 100% unbleached board fibres, available with plant-based polymers. The fibres are traceable throughout the supply chain.
