Challenges to be more sustainable
IMCD highlighted solutions
Increase the amount of recycled content
Many plastic packages cannot be sortable or recyclable. Some others can only support a small amount of recycled content to avoid performance loss. To allow and improve this, many products can help:
̕ • Compatibilizers that can enable the recyclability of multilayer packaging containing both EVOH and/or PA6.
• Nucleating agents to improve mechanical properties such as rigidity.
• Copolyesters that can help improve the sealing properties and aesthetics damaged by the increase of recycled content on their structures.
• Purge compounds to avoid dirty, black specks and can help minimise odour on the manufacturing plant.

Mechanical recycling preserves the molecular structure. It mechanically crushes the plastic and remelts it into a granulate tan that can be used again.
Granulates from mechanical recycling cannot be used in direct food packaging applications (except rPET coming from bottles). Apart from that, the colour of the recycled plastics tends to be black-grey and has an unpleasant smell.
Molecular recycling allows materials to be broken down into basic building blocks and then used to create new materials. Waste plastic can be recycled an infinite number of times. This process allows obtaining a recycled polymer with identical properties and aesthetics compared to the virgin one.
