The Irish packaging company Smurfit Kappa is introducing a new version of its Vitop bag for bag-in-box products. This consists of more than half recycled and renewable raw materials.
Smurfit Kappa is introducing a new and more sustainable version of its Vitop bag for Bag-in-box-products, the new Vitop Renew, which consists of bio-based PP resins is produced. This development now combines an approach that is already being pursued with the bag inside the box. This is made from EVOH e-recycled film, which contains raw materials from the chemical recycling of plastics. This means that the new bags are made from 53 per cent recycled and renewable material.
However, this chemical recycling does not replace mechanical recycling. Materials that are difficult to recycle mechanically are treated by pyrolysis. This process pursues a cycle-orientated approach and offers a new means of increasing plastic recycling rates as it can be applied to a wider range of plastic waste.
Bag-in-box already 75 per cent recyclable and renewable
The key difference between such materials and those from traditional mechanical recycling is that, after pyrolysis, the resins have the same properties as new polymers and can therefore be used for packaging with direct food contact.
„Such recycled resins are still only available in very limited capacities, their production requires new approaches, large investments and strong market demand,“ says Thierry Minaud, CEO of Smurfit Kappa Bag-in-Box. „The Bag-in-Box consists of already 75 per cent made from recyclable, renewable and biodegradable materials, as the design of the box is based on paper.“
„We are now going even further and are actively working with resin suppliers to increase the proportion of sustainable raw materials to increase. We are ready to launch pilot projects with our customers to increase the proportion of recycled and renewable material in their bag-in-box packaging,“ continues Minaud.
„Bag-in-box is proven to be the most resource-efficient packaging for liquids, with an unbeatable product-to-packaging ratio. These bio-based or chemically recycled products are characterised by the International Sustainability and Carbon Certification Plus Scheme (ISCC PLUS) certified and can be used like conventional polymer products by applying the mass balance approach.“ Pascal Reina, R&D Director at Smurfit Kappa Bag-in-Box
Vitop Renew and E-Recycled extend the Smurfit Kappa bag-in-box range of environmentally friendly products, following the introduction of the new, thinner film E-Compact 60 was added to the portfolio.
