Description

These 28mm Blue Liner Caps are standard plastic screw-on closures designed for use with PET bottles. Featuring an integrated blue liner, these caps provide a tighter seal than standard white-liner caps, helping to retain carbonation more effectively—ideal for sparkling wine, cider, beer, kombucha, and other carbonated beverages.

The tamper-evident design ensures product integrity and freshness, making them a reliable choice for both home brewers and winemakers. While the blue liner offers a superior seal, some users may find them slightly firmer to apply and remove compared to white-liner caps.

Made from durable polypropylene, these caps are well-suited for repeated use and perform consistently during storage and fermentation.
