Ultraseal Membrane Ends

Sonoco ultraseal membrane ends are lightweight, peel able and smooth. The easy, onepiece opening has no sharp edges, so cuts are a thing of the past. The ultraseal end is specifically designed for nonprocessed applications. The membrane creates a hermetic seal, keeping out oxygen, moisture and aroma. Ultraseal ends can be double seamed on existing equipment with minor modifications. They can also be printed for additional brand promotion.
