Sappi’s product innovation focuses on providing the market with fibre-based packaging solutions for applications that have traditionally relied on films, aluminium and multi-layer laminates. Our expanding range of functional papers supports the shift away from fossil-based materials towards renewable, paper-based packaging solutions. The papers deliver barriers to oxygen, water vapour, grease, aromas and mineral oil, which radically expands the scope for paper-based packaging applications and offers a viable replacement for fossil-based and non-recyclable materials. While fibre-based packaging is not new per se, what is new in Sappi’s development is incorporating new functionalities within the paper structure. Providing a barrier that fully delivers the protective function of packaging is essential if paper is to replace films or multi-layer laminate structures. Developing the innovation required to deliver heat sealability within functional papers also eliminates the need to add further sealing coatings or layers.
Moreover, it’s essential that the paper can run at high speeds and on existing machines without cracking or other damage. This is made possible by Sappi’s close partnership with OEMs, during which packaging machines are individually adapted to the properties of the barrier papers
By developing functional papers, Sappi strives to deliver fibre-based packaging solutions that provide exceptional product protection, run on existing packaging technology and contribute to a circular economy by being recyclable in the paper waste stream.
In collaboration with leading brand owners, Sappi’s functional papers have been launched in a number of applications, particularly in the areas of confectionary and tea.
