_Sustainable by Design!
Discover Mondi’s BiofilmsIt is important to create responsible solutions that create lasting value. Together with our customers and stakeholders along the value chain, we develop innovative and sustainable solutions that reduce material consumption, waste and CO2 footprint.
Biofilms
– Made from renewable resources – Excellent barrier properties (can be implemented) – 100% biodegradable and compostable – Increased shelf-life – Appropriate heat resistance – Good processing economics
Benefits for you:
– Thermoformable bio based and compostable barrier films i.e. for coffee capsules
– Extruded & thermoformed trays for organic meat – Dry food packaging with fat barrier
Applications:
– Blown film extrusion (mono or coex with oxygen barrier) – Cast film extrusion (mono or coex with oxygen barrier) – Cast extrusion coating (mono or coex with oxygen barrier)
with formable/ordinary paper or other substrates possible – Advantage: adhesive free coating, less chemicals
Technologies:
