Virgin fibre a necessity in chocolate packaging

/INS. “When we choose the paperboard for chocolate packaging, the decisive factor is taste and odour neutrality. Of course the paperboard must be suitable for the construction we have chosen but if we do not minimise the risk of the chocolate acquiring an off-taste from the packaging material then the rest does not matter.”

Tom Du Caju and his colleagues at Du Caju Printing & Packaging in Belgium are describing their experiences in food packaging. Du Caju is located in Erpe-Mere, just west of Brussels. With almost 50 employees and annual net sales of EUR 10 million, the company regards itself as a medium-sized Belgian converter. Of the packaging Du Caju produces, 85 per cent is food related and 11 per cent is chocolate packaging.

“In addition, just over ten per cent of what we do is packaging with direct contact between the food and the packaging material,” says key account manager Koen Penne. “We are choosing our food contact materials such as paperboard very carefully to avoid taint, odour and migration problems.”

Du Caju has been working with the world’s largest chocolate producer Barry Callebaut, for more than 25 years. The converter is regularly asked to create sophisticated promotional packaging for Callebaut as a sales tool and brand enhancer. The latest creation, The Origin Box, has an outer box made of a brown-coloured speciality paper from James Cropper, Colorscope Bitter Chocolate 350 g/m2. Inside the box are samples of chocolate from many countries. Each sample is packed in a wedge-shaped box made of Incada Silk 300 g/m2 from Iggesund Paperboard. The box also features a wheel giving information about the different types of chocolate. The wheel is printed on Invercote Creato 400 g/m2, also from Iggesund Paperboard,  and is covered with the same material as the outer box.

The brown material has a very matt appearance and a very natural look. The brown colour and the uncoated sides give a very good indication of the look of chocolate.The Origin Box was a finalist in the ECMA/Pro Carton European packaging award competition in 2014.

“We have learned from experience that only virgin fibre is good enough for this type of packaging,” comments Erwin Heeren, an experienced purchaser at Du Caju. “In choosing materials we also get support from our customer, Barry Callebaut, who tests all packaging materials for up to sixty days in its own sensory laboratory.”

As a purchaser he must also keep up to date with both the environmental debate and the discussion about how mineral oils in recycled-fibre-based materials can contaminate packaged foods.

“We are following the mineral oil debate with great interest, as are our most knowledgeable customers,” Erwin Heeren says. “However, we are not seeing any increased demand for traceability certificates for paperboard materials – neither FSC nor PEFC. That demand is constant at between three and five per cent of our total volume.”

The Iggesund Mill

Making the world’s best paperboard is easy. You need water, carbon dioxide and sunlight to grow a seedling into a tree. Then you need sustainable forest management that can deliver first-class timber. There must be a pulp mill and a paperboard mill, and then distribution channels to get the paperboard to everyone who wants to use it. Most important of all, though, to the manufacture of Invercote are the skilled professionals who do their best – people who are proud of what they achieve and do not compromise on the quality of their work. Iggesunds Mill has traditions stretching back to 1685. Throughout that time dedicated individuals have done their utmost to use the renewable forest to benefit other people.

A world-class mill

Iggesund Mill (including Strömsbruk Mill) in Sweden is one of the most advanced, fully integrated pulp and paperboard mills in the world. Not least thanks to our long term majority owner, we have very well invested mills. There are many benefits having an integrated saw mill – we manage raw material together and we can use all the waste from their production to either make pulp or energy. In return we feed the saw mill with steam used to dry the timber. At Iggesund Mill, 100% of the pulp used to make Invercote is produced on location and pumped wet to the board machine. This means that we use no market pulp. Not drying the pulp preserves some mechanical properties of the fibres.

This advanced technology – hundreds of metres of paperboard machines – is controlled by employees with various forms of special expertise. The machines work around the clock and year round to produce tonne after tonne of dazzling white paperboard. Technical perfection and numerical control processes are all well and good but for excellent results you also need team spirit and a good working atmosphere. Invercote’s unique properties are the result of the interplay between expertise, a positive spirit and cutting-edge technology.

Actively investing in bioenergy

In 2012 the new recovery boiler was inaugurated at Iggesund Mill, an investment made possible by the long term perspective of our majority owner. With it in operation, the mill produces all the heat it needs, and can also provide district heating to the nearby community. It also produces nearly all the electricity needed for the mill, and is connected to the grid to be able to output excess electricity if needed. As the new boiler was trimmed into operation, it drastically reduced a lot of emissions between 2013 and 2014: fossil CO2 by >85%, particles by ~45% and sulphur by ~35%

With the installation and trimming of the new recovery boiler, emissions to air have reduced drastically from already low levels – graph being updated shortly. Measurements have shown that only 1% of particles in the air of Iggesund village comes from the mill. The majority of particles comes from domestic fire places and cars.

Care for our customers and their businesses

Paperboard must be there when the customer needs it. All the quality features in the world are meaningless if the deliveries don’t arrive in time. Delivery precision is a high priority. A maritime transport system guarantees overseas customers receive shipments with the lowest possible environmental impact. The service doesn’t stop there. Every tonne of Invercote comes with access to documentation and knowledge about how to make best use of the paperboard. The knowledge and market-based technical support provided by Iggesund, help customers to achieve dazzling end results and optimal production economics.
