A package should save
more than it costs.

It all started in the 1940s, with the search for a better way to package milk.

Something that could protect what was inside—and the people who drank it—by keeping it safe and stable, even when refrigeration wasn’t available. Something efficient, with a minimized impact on the environment.

“Doing something that nobody else had done before is actually quite hard.”

Founder of Tetra Pak

What we set out to do had never been done, and it took a decade of development to create the first paper-based package that could do what we had in mind. Even the way we planned to fill it (and keep it safe, healthy, and free of bacteria in the process) presented a puzzle that eventually became one of our hallmarks.

Our aseptic cartons were considered one of the most important food innovations of the 20th century.

It was an enormous challenge. But it’s how we created the first Tetra Pak carton package, the distinctive tetrahedron-shaped packaging that inspired our name with its simple, efficient design.

For over half a century, we’ve been creating carton packaging that can safely and sustainably hold liquid food—including milk, of course—to meet the needs of hundreds of millions of people every day.

Today, we’re able to get food to people everywhere, protecting them by protecting what’s inside, with only minimal impact on our environment.

At Tetra Pak, we protect what’s good.

We still abide by our founding philosophy, the idea that packaging should save more—food and resources—than it costs. It's a way of thought that matters even more today than when we started
out—and one which will matter even more tomorrow.

Tetra Pak isn’t the only one protecting what’s good.

All over the world, people are hard at work in small ways on the things that matter to all of us most, from the environment around us to the food that fuels us.

They’re changing how we raise, consume, and think about food, how we care for ourselves and our resources, and they’re sharing the kind of ideas that will change our future for the better.

They’re doing it at the grassroots, quietly and without fanfare.

We’re sharing their stories.

At Groundwork, we’re giving them the attention they deserve: yours. We’re sharing their stories so you can, too.

It’s just one small way you can make an impact. Because when it comes to innovation, inspiration, and changing the world, sometimes one good idea, shared, is all it takes.

Spread the word.

These paperboard cartons
are a big deal.

When Dr. Ruben Rausing invented a new way to package milk, he probably didn’t realize he’d just changed the world.

It didn’t take long to figure out that these cartons were perfect for packaging more than milk. Today, airtight, shelf-stable Tetra Pak® cartons are used around the world to keep juice, water, soup, olive oil, nutritional shakes, vegetables, and more safe and sound.

So how does it work?

Tetra Pak cartons use multiple layers of materials to ensure nothing gets in or out of the package. The cartons are made mostly of paperboard, with thin layers of plastic and aluminum working together to keep light, oxygen, and bacteria out, meaning no contamination and no preservatives needed. Ever.


By protecting the integrity of the product, the carton preserves both the taste of the food and all the essential nutrients stored inside.

When it comes to packaging materials, these cartons keep it to a minimum.

In fact, Tetra Pak cartons have a better package-to-product ratio than an egg. By using just the right amount of material, Tetra Pak can ensure maximum product protection while using minimal resources.

Cartons help protect more than just our foods.

Protecting our environment, our food sources, and our natural resources is an essential part of preserving our shared future. That’s why Tetra Pak is committed to using renewable materials—natural resources that replenish over time—and meeting environmentally friendly manufacturing standards.

100% of the paperboard in Tetra Pak cartons is Forest Stewardship Council Chain of Custody certified, meaning all of it can be traced back to responsibly managed forests.

And after they’ve been recycled, the cartons can be turned into tissue, paper products, and green building materials.

By using sustainably sourced, renewable materials, Tetra Pak cartons are protecting our foods, preserving our natural resources, and promoting environmentally conscious practices.

Designing the Perfect Sip

Behind every great innovation is a series of trials and errors that takes time and effort.

Decades after mastering the packaging technology behind the juice box, international packaging company Tetra Pak set out to tackle a new challenge: creating the ideal drinking experience to keep up with today’s fast-paced consumers. But how do you revolutionize something as innate as, well, drinking?

Testing the water (and the people that drink it).
Before Tetra Pak could begin taking steps towards developing a revolutionary product, the team had to first figure out what the “ideal drinking experience” meant. So they launched a comprehensive ethnography research project to collect insights and information on cultural drinking habits around the world.

They discovered that consumers were no longer only drinking at home; they were mobile and wanted products that moved with them from one place to another. They also identified three different styles of drinking: suck, pour, and pull.

Different people in different
situations drink very differently.

With these insights, they went back to the field to test out a handful of designs that enabled all three drinking types, even going as far as putting cameras inside different packages to record how people’s mouths worked. (Strangely, no one had looked that closely before.)

By observing how people interacted with their product—and the world around them—they found that a series of small changes could refine the drinking experience to everyone’s liking, in particular for those on-the-go, whether sucker, pourer, or puller.

A series of small changes—extending the cap’s neck, widening the opening, and shifting its position from the center to the edge—gave consumers easier access and improved control of the flow.

It was these small changes that eventually led to the ergonomically designed and positioned DreamCap™.

Designer made. Consumer approved.
After another three years of engineering and finessing, the DreamCap was finally unveiled in 2011 and introduced with the Tetra Prisma® Aseptic carton in Saudi Arabia before making its way to the United States, where it became the cap choice of brands like Vita Coco and Muscle Milk.

That same year, Tetra Pak also released a renewable bio-based version made from plastic derived from sugarcane, marking a significant step toward the company’s goal of producing fully renewable packaging.

When done right, design can turn
a necessity into an experience.

Today, the award-winning DreamCap is a modern example of innovation developed with in-depth consumer insight and research and evidence of just how important it is to know your consumers.

And while products like Tetra Pak’s DreamCap might seem simple enough, the truth is that for every small detail, there’s an iceberg of innovation underneath.
