Flexible Packaging
Vegetable packaging 2.0
made eco-friendly A complete turnaround for onion packaging was invented when Paptic and Marvaco joined forces to respond to a call from Puukin Tila, a farm established in 1659. Paptic fibre-based material and Marvaco expanded gamut printing with Flint Group C2C inks, made the new, truly sustainable packaging possible.
P
etri Puukki, the farmer from Puukin Tila, wanted a new, sustainable alternative to their previous plastic onion packaging. The partnership with Paptic and Marvaco led to optimised packaging from all sustainability aspects, including the substrate, design, printing, and inks. The result is now ready for the ‘Super Onion’.
Paptic, a fibre-based substrate, is a completely new kind of sustainable innovation. The lightweight material is soft, with excellent puncture and tear resistance and heat sealable properties. Katja Jokiaho, Business Development Manager from Paptic, says: “In our quest to reduce plastics, we need to approach the end- uses where plastics are mostly used for flexible packaging. Many products are overpackaged today simply because there have not been any alternatives to plastic based solutions. There are however many products, especially organic, which benefit from being packed in more breathable materials. Heat sealable Paptic materials run on existing lines, currently using
plastic films. Testing the material’s suitability for specific goods is very easy: no investments are needed to adopt this fiber-based solution. We were very happy to start this project with Puukin Tila, where we looked at the packaging from all angles, including the use of sustainable inks and assessing the material’s efficiency in packaging design. We see that as awareness increases rapidly, consumers very much appreciate the possibilities to make environmentally wiser choices.”
The target was to create a simple, sustainable design for exceptionally packed onions by reducing ink consumption and the number of colours used in printing, explains Mirva Koskinen, Brand Sales Manager at Marvaco. This was achieved through Expanded Gamut Printing (EGP™). A GreenerPrinting logo on the package is used to inform consumers about the sustainable choices made in the printing process. “The printing process uses the most modern technologies,’’ says Kai Lankinen, Marvaco’s executive partner: “We minimised the number
of inks and still achieved a colourful design using just three colours, made possible thanks to the printing process. The water-based inks from Flint Group are cradle-to-cradle Gold-status certified and offer industrial compostability. In selecting these inks, we eliminated the use of heavy metals and minimised ink consumption and waste. The careful selection of inks for better sustainability is certainly something that packaging designers are interested in hearing more about”.
The project was completed in just a few months and the new packaging is rolling out into selected stores during spring 2022. Petri Puukki is very happy with the results and states: “We wanted to make a difference and pack our locally produced onions in a sustainable way. Partnering with other pioneering companies with the same mindset was a natural choice for us. Material selection keeps the onions fresh longer and the new packaging also looks fresh!”
