How can brands choose label materials that support recycling goals?

Brands can support recycling goals by selecting label materials, adhesives, inks, and coverage that are compatible with the container’s specific recycling stream. For PET bottles, this often means considering floatable PE or PP label or sleeve technologies that separate from PET during reprocessing; for polypropylene containers, a compatible polypropylene in-mould label can support a mono-material approach.

The starting point is the container resin and the recycling system used in the target market. Polymer similarity alone is not enough: PETG, for example, should not be assumed to be a suitable sleeve for PET bottle recycling simply because both contain PET chemistry. Density, separation behaviour, inks, adhesives, coverage, and sorting performance all influence whether the decorated container remains compatible with the recycling stream.

Where a mono-material construction is practical, such as compatible IML on a PP container, it can simplify recycling. For applied labels and sleeves, brands should prefer technologies with current third-party recognition or test evidence for the relevant stream and market, and should minimise features that interfere with sorting or washing. Any recyclability claim should also reflect real local collection and reprocessing infrastructure, not only laboratory compatibility.
