MONO-MATERIAL PACKAGING: EASY TO RECYCLE Multi-material packaging that is made from different types of materials is difficult or impossible to recycle because separating the layers is technically and economically challenging. Mono-material packaging avoids this issue and will play a key role in the future because it is easier to recycle. Several recycling organisations all over the world have issued recycling recommendations highlighting the advantages of mono-material structures. More specifically, mono-material packaging – made primarily from a single polymer like PE or PP – is easier to recycle than multi-layer composites (e.g., plastic-aluminium or plastic-paper), which are often non-recyclable. EVAL™ EVOH, used in thin layers (≤10%), provides high-performance oxygen barriers while maintaining recyclability:
To help producers meet PPWR requirements, recycling organisations have published guidelines. In general, they recommend structures with over 90% of a single polymer type , and EVOH stands out as the preferred barrier material in polyolefin recycling streams. There are three ways in which EVAL™ EVOH can help you design packaging that is in line with the recyclability, reusability and minimal waste principles of the PPWR. How EVAL™ EVOH enables you to solve your packaging challenges
• It is recognized by recyclability guidelines as non-disruptive to recycling streams • It is compatible with both mechanical and chemical recycling, offering a full end-of-life solution
Mono-material structures typically consider to meet grade A or B recyclability performance grades set by the PPWR regulation, especially when barrier layers like EVAL™ EVOH are kept below 10% of total weight.
1. Mono-material packaging — We can help you find a mono-material alternative for traditional multi-material packaging.
2. Optimise your packaging — If you are already using EVAL™ EVOH in your packaging, we can help you with down-gauging or structure optimisation.
3. Paperisation — Add a thin layer (5% or less) of EVAL™ EVOH to fibre-based packaging to create an effective barrier and maintain recyclability.
