The Aluminum Foil Seal is a liner designed to provide a strong, tamper-evident barrier between the cap and the container. When a bottle sealed with this liner is opened for the first time, the foil is visibly broken — giving consumers and end-users immediate confirmation that the product has not been tampered with. This makes it a preferred choice for food and beverage, pharmaceutical, nutraceutical, and chemical applications where product integrity is paramount.

Available in thicknesses from 0.6mm to 1.0mm and in a wide size range from 10mm to 160mm, these foil liners can be matched to virtually any standard cap diameter in the Nextech lineup. The foil layer also acts as a moisture and oxygen barrier, helping to extend shelf life. Wholesale pricing is available — contact Nextech Packaging for volume quotes and lead times.
