11 Jun 2021 --- Mondi has partnered with cheese packaging company Hazeleger Kaas to create EnvelopeForm, a mono-material polypropylene (PP) solution for Westland Kaas’ Maaslander cheese slices. Mondi says most sliced cheese in Dutch supermarkets is still packaged in hard-to-recycle mixed material film. To improve recyclability, the new packaging has a PP thermoforming top and bottom web, while replacing the paper label with PP material.
