As single-use plastics face bans, Tetra Pak unveils biodegradable paper straws for juice and milk cartons, driving industry-wide sustainable innovation.

Tetra Pak’s Breakthrough in Sustainable Packaging: Biodegradable Paper Straws

As global awareness of plastic pollution intensifies and governments impose bans on single-use plastics, industry leaders are being challenged to innovate. Tetra Pak, one of the world’s largest food and beverage packaging companies, has made a transformative leap: the introduction of biodegradable paper straws for use on its signature juice and milk cartons. This pivotal development places Tetra Pak at the forefront of efforts to reduce plastic waste and foster a low-carbon circular economy.

Why Replace Plastic Straws?

Plastic straws, though small, have become symbolic of unsustainable single-use plastics. They are largely not recyclable through standard systems due to their size, and their improper disposal can lead to environmental harm in oceans and landfills. With plastic straws commonly affixed to the side of drink cartons—especially those targeted at children—delivering an eco-friendly alternative was a significant technical and market challenge.

Global plastic waste crisis has led to increasing government and industry regulation.
Small plastic straws are difficult to recycle and can contribute disproportionately to environmental litter.
Consumer demand is swiftly shifting toward sustainable packaging options.

The Problem: Single-Use Plastics and Their Environmental Impact

Over the last decade, the adverse environmental implications of single-use plastics have become starkly evident. Beverage straws and packaging make up a disproportionate share of plastic debris, as their small size and lightweight nature mean they are often not captured in recycling streams. Environmental advocacy and mounting regulatory pressure have pushed manufacturers to devise alternatives that minimize or eliminate the use of conventional plastics.

Plastic waste accumulates in landfills and oceans, harming wildlife.
Bans and restrictions on single-use plastics in multiple countries.
Increasing consumer skepticism of brands that do not prioritize sustainability.

The Solution: Tetra Pak’s Biodegradable Paper Straws

In response to the global plastics problem, Tetra Pak developed a biodegradable and compostable paper straw designed precisely for its small carton formats. These straws are made from Forest Stewardship Council (FSC)-certified paper, ensuring responsible sourcing. Unlike their plastic counterparts, these straws can be recycled together with the carton when pushed inside after use, offering a fully integrated, circular solution.

Material: FSC-certified paper—sustainably sourced, biodegradable, and food safe.
Functionality: The paper straw is engineered to match the performance of plastic, resisting sogginess for a typical drinking window of several hours.
Compatibility: Designed for Tetra Pak’s small carton lines (200 ml and similar), widely used for juices and dairy drinks.

The new straws meet rigorous international food safety standards and are manufactured to be robust enough for practical consumer use. Field trials across Europe and other regions have confirmed their viability, leading to phased public launches on retail shelves.

Design and Material Innovation

The transition from plastic to paper for straws involves unique material science challenges. The primary hurdles include:

Ensuring the straw is strong enough to puncture the foil cover of cartons.
Maintaining structural integrity in liquid for several hours without decomposition or breakage.
Guaranteeing food safety and chemical compliance at all points of the supply chain.

Tetra Pak’s straws are constructed using multiple layers of high-quality Kraft paper bonded together with food-safe adhesives. These layers add both durability and a comfortable mouth-feel, while ensuring the straw’s performance is consistent across different types of beverages such as juice and milk. The full recycling integration is a critical advantage: when the consumer pushes the straw inside the empty carton after use, both can be processed together at recycling facilities, supporting circular materials flow.

Sizing and Packaging

Available in U-bend and straight configurations to fit standard 125ml, 200ml, and 250ml Tetra Brik Aseptic pack sizes.
