20mm Pressure Sensitive Cap Liners - 30 Pack Torque Activated Seals For Glass And Plastic Bottles

About This Product

Hey small business owners, crafters, and anyone who needs to seal bottles properly - these 20mm Pressure Sensitive Cap Liners are about to make your life so much easier! This pack of 30 seals gives you plenty for multiple projects, and the best part is you don't need any special equipment - no induction sealer, no heat gun, no shrink bands required. These are torque-activated polystyrene foam liners coated with special adhesive that seals when you screw the cap on tightly. They measure exactly 20mm (0.78 inches) in diameter and work with any glass or plastic bottles or jars that use 20mm caps. The application is simple: clean your container top thoroughly, center the white foam side down on the jar, then screw your cap on tightly and don't remove it for 24 hours to let the adhesive fully set. These liners provide serious protection against leaks and keep your dry products or powders fresh and dry. They create an actual seal that's way better than basic foam liners alone. Once applied, they peel off cleanly when needed (though they are single-use). Important notes: they work best with powder or dry products, avoid overfilling your containers, and they're not suitable for oil-based applications. Made right here in the USA, these professional-grade seals are exactly what herbalists, spice sellers, crafters, and small manufacturers use to give their products that professional, sealed freshness. Whether you're packaging spices, herbs, crafts, or any dry goods, these pressure-sensitive liners deliver that store-bought quality seal that customers expect and your products deserve!
