In many cases, cartonboard solutions with a barrier can now be an alternative to plastic packaging for sophisticated foods such as chocolate or baked goods. The new truffle packaging from Kultasuklaa is a good example of how cardboard can be used as a sustainable packaging solution even for premium foods.
Recyclable, biodegradable and made from renewable materials: These are the properties that companies and consumers increasingly expect from packaging – including food packaging. However, food in particular often requires a grease or moisture barrier. This is why many manufacturers and consumers initially think of plastic-coated packaging in this context.
However, cardboard solutions with a dispersion barrier coating and a varying degree of grease and moisture barrier can often also be used. This is because these are recyclable and can be processed in paper and cardboard recycling: At over 80 per cent, paper and cardboard packaging has a very high recycling rate. This is a very important factor, as packaging for consumer products now accounts for more than half of all packaging produced worldwide.
Dispersion barrier against grease and moisture
In addition to a high recycling rate, cardboard solutions also score points with other qualities: Finnish board manufacturer Metsä Board, for example, relies on pure virgin fibres that can be traced back to their origin in sustainably managed Nordic forests. The material is lightweight, yet very stable and can be used in a variety of ways for offset, flexo and digital printing. With a dispersion barrier coating, it is used to produce the board quality Metsä Board Prime FBB EB, which is suitable for direct contact with food and offers medium-strength protection against grease and moisture thanks to its dispersion barrier.
Distinctive packaging design
For more than 30 years, the Finnish family business Kultasuklaa in Lasimäki has been producing artisan chocolate products using only first-class quality and premium ingredients for its chocolate bars, confectioneries and truffles. With a new eye-catching hexagonal packaging solution made of virgin fibre cardboard, the company not only attracts a lot of attention at the PoS for its truffles but also reduces the use of plastics and thus lowers the environmental impact of its products without compromising the shelf life of the valuable ingredients.
The chocolate manufacturer also attaches great importance to the fact that the raw materials used for the packaging are sourced locally and produced in an ethically responsible manner. The company chose Metsä Board Prime FBB EB as the material for the packaging. The packaging material is produced in Finland at Metsä Board’s Kyro plant.
Reaching the goal together
In addition to Metsä Board, numerous other companies were also involved in the production process: The structure of the packaging was created by CadPack, the layout was designed by DesignCompany and the printing was carried out by Markprint. The striking and functional packaging solution is therefore not only a good example of how paperboard can be used for food packaging, but also shows that the results can be achieved through successful collaboration. For this reason, Metsä Board offers co-creation workshops at its Excellence Centre in Äänekoski, where the company’s packaging team works together with customers and experts from various industries to improve current packaging or develop new solutions.
In addition to the wide range of analysis tools offered by the Excellence Centre, these workshops primarily provide the opportunity for a joint exchange. Challenges of the product and requirements for its packaging are thus made visible right at the start of the planning process, and the partners can address them early on in the process. The result is efficient, sustainable packaging that is tailored to the needs of the product, especially when the product in question is a sophisticated confectionery.
