The barrier properties of the UPM SwanBarrier papers, such as water vapour barrier and medium grease resistance, have been achieved without any PE-coating or fluorochemicals. Thus they are fully recyclable and biodegradable.The UPM SwanBarrier papers are developed for dry and greasy foodstuffs, for example bread bags and biscuit and greasy food wrappers.“With this barrier paper range we want to answer customers’ needs for a recyclable and biodegradable packing material. We also wanted to make a barrier paper with existing barrier paper properties without using non-degradable components,” says Timo Lehmuskallio, Product Manager, UPM Packaging papers.
