SUSTAINABLE PACKAGING
technology that is more commonly used to join metals, with parts being joined without the need for a filler material. Instead, layers of cardboard are perforated from one side with a needle, forming a collar on the other side, which is then pressed onto the cardboard – creating a stable force & form fit. Schubert’s aim was to achieve at least the same stability and strength with Dotlock that is possible with a glued joint. Manuel Schuster, Head of New Component Development at Schubert, explained: “We had to fundamentally rethink our understanding of the process. With Dotlock, the strength that is usually provided by the glue is achieved by the number and arrangement of the
perforations. For example, several holes can be made in corners that require greater strength. The hole size also varies depending on the cardboard thickness. The geometry of the hole distribution is redefined for each new pack, as it is important to prevent the cardboard from tearing if the perforations are too closely set or if the joint is not strong enough should the perforations be too widely set.” Dotlock can be used wherever solid board
Simulated success for Mars
Mars recently announced that it is adopting simulation software in a bid to reimagine its packaging innovation process through digital technology. It will be using Ansys software to perform virtual testing and prototyping on new packaging innovation, initially across its snacking portfolio, which will minimise the need for extensive physical testing during the packaging development process and will provide in-depth insights into different aspects of complex

production phases, including wrapping, drop tests and failure scenarios. Using the simulation technology, researchers at Mars have already reported reductions in development time of up to 40% through computer modelling and in the quantity of plastic purchased by Mars for testing by approximately 246 tons. The organisation is working to redesign more than 12,000 packaging types across its portfolio to fit with the recycling infrastructure that either exists today or is
likely to exist in the future, making it easier for consumers to recycle their packaging.
“In the world we want tomorrow, no packaging becomes waste,” says Qing Qi, VP R&D global innovation, Mars Snacking. “This vision is at the heart of our ‘Sustainable in a Generation’ plan and it will only become a reality by leveraging breakthrough science, innovative thinking and partnerships to push the boundaries of what’s possible.”
packaging is involved. It is said to be well suited for trays, base-lid applications and gable-top packaging, for example, in which confectionery such as chocolate, bars or pralines have traditionally been packaged. Schubert’s new hybrid packaging material consists exclusively of cardboard and very thin monofilm – which can be easily separated after use, making it fully recyclable. Laura Gascho, plastics engineer at Schubert, takes up the story: “Many companies have asked us for alternatives to plastic trays and blister packs. There are currently no compelling sustainable solutions on the market, especially for products that require a barrier, such as sensitive snacks that need to be protected from outside air and moisture.
