made with a minimal amount of material and maximum hygiene. Ruben Rausing, Tetra Pak’s founder, wanted to develop a package to eliminate hassles for milk con- sumers and producers alike by creating a solution much lighter and user friendly than unwieldy metal canisters or heavy glass bottles • Tetra Classic Known as Tetra Classic and first marketed in 1952, the first of Tetra Pak’s carton packages was shaped like a tetrahedron and extremely efficient. It is still around and consumers in the industrial and commer- cial spaces still consider it as contemporary and modern as when it was first launched • Tetra Brik Tetra Brik intro- duced the optimal, efficient brick shape to the market- place. It was a simple yet smart design that today is the staple for milk packages in Europe, Asia, the Middle East and South America • Aseptic Technology In 1961, aseptic technology was introduced. It’s a difficult name for a simple technolo- gy—heat treatment—that truly changed the way people consume milk. The system immedi- ately enhanced the dairy industry ’s backstory. Shipping costs were considerably reduced because of the light weight of Tetra Pak packages, as well as their shape. A fully packed basket held more liquid in a given space than a batch of cylindrical bottles or cans. Even more significant, the fact that perishable products like milk pack- aged aseptically in Tetra Pak cartons remained wholesome and tasted fresh without refrigeration for up to a year eliminated the need to maintain a “cold distribution chain” from the manufacturing plant to the grocery store. As a result, the practical radius within which products could now be shipped was dramatically expanded, making it possible for a single plant to service a much larger customer base, producing further savings. As Rausing put it, “Doing some- thing that nobody else has done before is actually quite hard. ” In 2004, both Tetra Classic and Tetra Brik found their way to the MoMa in New York City. The museum included Tetra Classic and Tetra Brik cartons in its “Humble Masterpieces” exhibition, a showcase of everyday “inspired designs that help make life easier, safer and more fulfilling” • Tetra Top In 1986, Tetra Pak was ready to launch a system that would revolutionize the chilled cases in grocery stores. The Tetra Top was the first carton bottle for chilled applications, both high acid (juices) and low acid (dairy). It was a package that combined a carton sleeve with a plastic top, bringing innovation and added convenience to the chilled case while maintaining the environ- mentally superior profile of carton packages. Utilizing state of the art technology, this system forms the whole package inside the same filling equipment machine, includ- ing the top. The core essence is the lid forming/injection molding technique. In 1988, right after the package was launched, the injection molding was used in a cycle speed of 2.1 seconds—a world record at that time. By comparison, a Swiss company making molds for Ferrari was molding at 2.5 seconds • Tetra Recart Another innovation in carton packaging was introduced in 2003, named Tetra Recart. It was the first retortable carton to be launched, offering an alternative packaging solution for a number of food products which have traditionally been packed in cans or glass jars. When first conceptualized, our own industry could not envision a carton that could ever resist the extensive hot water baths used in the retorted process. It took 10 years for the new packaging system to be developed • Tetra Evero Aseptic In 2011, Tetra Pak again set a new industry standard with the first aseptic carton bottle for white milk to hit the market. Tetra Evero Aseptic was a real innovation in packaging design and the result of years commitment, invest- ment and industry know how. It delivered a completely new carton shape that provided ease of use, high impact brand- ing opportunities, cost effectiveness and value. A range of design and engineering challenges demanded technological solutions and new processes, which came together to create this packaging shape. This included an industry first “gas phase” sterilization technique and advanced injection molding technologies to fuse the top, carton sleeve and capped neck into a ready to fill package. This was all covered by 14 design and application patents “In 1988, right after Tetra Top was launched, the injection molding was used in a cycle speed of 2.1 seconds—a world record at that time. By comparison, a Swiss company making molds for Ferrari was molding at 2.5 seconds.” 34 FLEXO MARCH 2014 www.flexography.org
