3.5.2 TINPLATE CLOSURE
MATERIAL
DECORATION
MATERIAL Only ferromagnetic (alloy) metals should be used to prevent contamination in recycling. A lacquer coating does not interfere with the conventional recycling process In the recycling process of aerosol cans, an additional treatment step is required, which is why the design is rather disadvantageous. Aerosol cans with non-hydrocarbon-based propellants are preferable Aerosol cans with hydrocarbon-based propellants and spray cans with high residual contents are particularly problematic.
DECORATION AND OTHER COMPONENTS Embossing does not have a negative impact on recycling. Direct printing on the packaging should be done with EuPIA-compliant coatings and printing inks. Paper banderoles can also be used without any problems. Non-compliant inks can reduce the quality of the secondary material. PVC labels should be avoided as they can cause problems during processing in the recycling process.
CLOSURE SYSTEM In the best case, closures are also made of ferromagnetic (alloy) metals, as these can be recycled together with the base material. Plastic caps and valve caps should be designed in such a way that they can be separated before disposal or during the sorting process.
