Nissha and Tetra Pak develop aseptic milk carton with paper-based barrier

Nissha Metallizing Solutions (NMS) and Tetra Pak have collaborated to create an aseptic beverage carton with a paper-based barrier, featuring paper from FSC-certified sources.

NMS says its paper-based portfolio includes recyclable, renewable and mono-material solutions utilizing paper from FSC-certified (FSC-C109768) forests and other controlled sources. These solutions are said to deliver the required level of protection from oxygen and light through the application of different coatings.

The company adds that its products ‘decrease dependence on non-renewable resources’ compared to the barrier layer used in traditional aseptic cartons. Apparently, the paper-based barrier is also expected to have downstream benefits where cartons with a higher fibre yield are likely to become more attractive to paper mills.

In this context, NMS states the paper-based barrier represents an opportunity for recycling infrastructures and their efficiency, since it changes the material structure of the carton package from three to two main materials – paper and polymers.
