Carton openings

SIG offers convenience on top of the carton pack – with the perfect opening solution for each volume and format.

Tethered caps by SIG

SIG has developed tethered caps ready for market launch in Europe well in advance of the 2024 deadline, reassuring customers that SIG remains the right partner to help them meet consumer demand for sustainable packaging and stay ahead of European regulatory requirements.

The first tethered closures launched are SIG MaxxCap Linked and SIG SwiftCap Linked for our core family-size carton portfolio as well as SIG DomeCap Linked for our SIG Dome carton bottle. With SIG SmartCap Linked, the first tethered closure for single-serve packs from SIG is now available.
