What if the next big leap in packaging wasn’t about adding more, but refining what’s already there? In a market where differentiation, efficiency, and sustainability all compete for attention, even the smallest innovation can create a powerful impact. That’s exactly what Tetra Pak and Iceland’s Mjólkursamsalan are proving with the world’s first trial of Tetra Pak® Debossing on carton packaging – a subtle yet transformative effect designed to elevate the consumer experience, create a premium look and feel, and enhance brand value.
A partnership built on innovation and trust
For more than six decades, Tetra Pak and Mjólkursamsalan have shared a commitment to pushing the boundaries of dairy packaging. Their partnership dates back to 1958 – a time when the Icelandic dairy industry was expanding rapidly, and Tetra Pak’s pioneering cartons offered a revolutionary alternative to glass. Over the years, that collaboration has evolved through technological leaps and changing consumer demands, anchored by a shared belief in innovation as a driver of growth.
“We truly value the strong and trusted relationship we’ve built with Tetra Pak over the decades,” says Halldóra Arnardóttir, Marketing and Product Category Manager at Mjólkursamsalan. “Their forward-thinking approach aligns closely with our own ambition to deliver high-quality products while staying ahead of market trends. By working together in this spirit of innovation, we’ve been able to grow, adapt, and create lasting value for our consumers.”
That mutual trust has enabled both companies to move quickly from concept to trial with a new innovation that may well redefine how brands use surface design in packaging.

From pressure to differentiation
In today’s ever-changing chilled food and beverage sector, standing out on the shelf is more complex than ever. Brands must balance premiumisation with sustainability, aesthetics with efficiency, and constant innovation with cost control. So now, for many producers, packaging is no longer just a container for their product – it’s become a strategic tool to capture attention and convey their brand’s values.
This is where Tetra Pak® Debossing comes in. Developed by Tetra Pak for use on Tetra Rex® packaging solutions, the technique introduces ultra-fine indentations into the surface of the packaging – essentially a form of debossing – creating a refined texture that subtly interacts with light. The result is an enhanced tactile and visual experience – a new layer of sophistication that’s achieved without adding materials or altering the package structure. Importantly, it uses the same equipment and processes customers have already invested in, ensuring operational efficiency and cost optimisation.

But every step forward requires a customer willing to embrace the future. “When we innovate, we are highly dependent on having a close collaboration with our customers,” explains Martina Hansson, Solution Manager Chilled Solutions at Tetra Pak. “So, having such a close relationship with Mjólkursamsalan is beneficial in many ways. We’re able to be transparent towards each other, both regarding our needs as well as opportunities, and it ensures we get valuable feedback on what we work on.” Joining forces with such customers is, she adds, key to bringing innovation to the market – and ensuring it succeeds.
“As Tetra Rex® and gable top packages are very iconic and established on the shelves, we wanted to create another dimension to package design.”

Industry-first trial of customised debossing
Mjólkursamsalan is the very first of Tetra Pak’s customers to trial this new packaging effect – beginning with its flagship ab mjólk brand, one of Iceland’s best-known dairy products. The choice was deliberate: ab represents quality and leadership in the market, making it the perfect platform to test a premium innovation.
“We were excited to explore Tetra Pak® Debossing together with Tetra Pak, and saw a great opportunity to test it on our ab milk brand,” says Arnardóttir. “The brand represents high quality and leadership, and we see Tetra Pak® Debossing as a natural fit, adding a refined, premium touch to the packaging. It offers something extra for the consumer experience, not just visually but also through the tactile feel, helping the product stand out on the shelf in a subtle yet sophisticated way.”
The effect may appear small – tiny variations measured in just a few microns – but its implications are significant. It allows brands to differentiate products without changing material composition or increasing weight, meaning sustainability performance remains uncompromised. For Mjólkursamsalan, it’s a way to enhance their brand while optimising its existing Tetra Rex® and gable top equipment, a key business consideration when it comes to dairy (and milk in particular).
“As Tetra Rex® and gable top packages are very iconic and established on the shelves, we wanted to create another dimension to package design where customers are still able to use the equipment they’ve invested in,” explains Hansson. “With this latest innovation, we’re aiming to launch in limited scale during 2026, and look forward to finding new ways of utilising what we have.”
"Easy production is very important. The new material went straight into commercial production, and it ran perfectly thought the machine.”

Aligning innovation with business value
This initiative also reflects a broader shift in the packaging industry: innovation must now deliver measurable value. Producers are looking to optimise their production without disruption, enhance their brand’s perception without excess cost, and unlock consumer engagement without compromising on sustainability.
Tetra Pak® Debossing meets these expectations by combining design differentiation with production efficiency. It’s a tangible example of how technology and collaboration can strengthen brand equity while maintaining operational reliability, a balance that’s critical in today’s cost-conscious chilled food and beverage sector.
Looking ahead to a centenary celebration
For Mjólkursamsalan, the trial also carries symbolic weight. As the cooperative approaches its 100th anniversary in 2027, the company is looking for meaningful ways to honour its heritage while embracing the future.
“If the trial yields strong results, we see great potential to expand micro debossing across a broader range of our products,” says Arnardóttir. “As we approach our 100th anniversary, we’re already thinking about how this innovation could help us mark that milestone with special edition packaging that celebrates our heritage in a modern, premium way.”
By adding both visual and texture value, Tetra Pak® Debossing enhances the consumer experience – placed correctly, it can add grip, making packaging more functional. It can be yet another tool for clever designers looking to elevate their packaging, it’s use limited only by their imagination. “Looking ahead, it could also inspire others in the dairy or food industry to explore more creative and sustainable ways to differentiate their products,” adds Arnardóttir.
A shared vision for the future of packaging
In the end, this Tetra Pak® Debossing trial is more than just a technical test – it’s a reflection of a partnership that has stood the test of time. By combining Mjólkursamsalan’s consumer insights and market leadership with Tetra Pak’s technological expertise, the two companies are demonstrating how long-term collaboration can continue to unlock new opportunities for efficiency, creativity, and growth.
In an era where packaging innovation often focuses on bold graphics or new materials, micro debossing offers a subtler, smarter path forward – one that enhances, optimises, and differentiates without compromise. For Tetra Pak and Mjólkursamsalan, it’s proof that even after 57 years, the most enduring partnerships are the ones unafraid to embrace the future, and to take the lead where others will eventually follow.
