What materials are shrink sleeves made from?

Shrink sleeves are commonly made from PETG, PVC, OPS, and purpose-designed polyolefin shrink films. The right material depends on the shrink ratio required, container geometry, print and appearance requirements, heat-tunnel conditions, cost, and the recycling pathway targeted for the finished package.

PETG offers high clarity and strong shrink performance for complex shapes, while PVC and OPS have different cost, shrink, and temperature characteristics. However, PETG should not automatically be described as compatible with PET bottle recycling simply because it is PET-based. Current design-for-recycling guidance for PET bottles can treat PET/PETG sleeve materials as incompatible with the conventional PET stream, while properly designed floatable PE or PP sleeve constructions may be preferred. Specific sleeve technologies can also receive compatibility recognition after testing, so the exact construction matters more than the polymer name alone.

Material selection should therefore consider both packaging performance and end-of-life design. Sleeve density, coverage area, inks, perforation or removability, optical sorting behaviour, and compatibility with the bottle resin can all affect recyclability. Brands should verify the exact sleeve construction against current APR, RecyClass, or other applicable local design-for-recycling guidance rather than assuming that an entire material category is recyclable.
