The vacuum bags from Caso are compatible with many commercially available vacuum sealers, including appliances from various brands. However, there is no direct indication that they are specifically compatible with the Zwilling system. Adapters are being sought for Zwilling Fresh & Save boxes to connect them to Caso vacuum sealers, which indicates that the systems are not readily compatible and an adapter is required.

To summarise: The bags themselves are suitable for many vacuum sealers, but the Zwilling Fresh & Save boxes require a special adapter to use them with Caso systems.
