Abstract

The BioBoard project is build built on past research that has revealed that whey protein coating can provide bio-degradable plastic layers that can replace existing plastic coatings in multilayer packaging and enhance their recyclability by separating the individual fractions of the multilayer packaging [1]. To this end, a tailored coating system based on the renewable raw material derived from agrofood waste and its technological application is beinghas been developed for extrusion coating paper, paperboard and cardboard to produce packaging materials. About 7 million tons of coated paper, paperboard and cardboard are currently manufactured annually worldwide. Typical laminate packaging contains about 20 mass percent of petrochemical based polyethylene (PE). Increased political, legislative and consumer pressure to reduce the dependency on fossil fuel based plastics, but also to produce recyclable solutions, poses a major challenge for packaging producers to seek alternative materials that do not harm the environment in their manufacture and end of life, are based on a sustainable resources, and offer similar performance to their conventional plastic counterparts. To this end, there is a great need to provide producers of coated paper, paperboard and cardboard manufacturers with a bio-based material without compromising the humidity barrier properties of the resulting packaging materials and overcoming the current challenge to the recycling of such packaging.
