Peelable Membrane Closures

Safer. Easier.

Sonoco membrane ends eliminate sharp edges for safer, easier package opening.

Lose the can opener! Your customers will only need a
thumb and forefinger to open your product after you convert
to a Sonoco peelable membrane closure.

Our closures have no sharp edges and a low opening force. Contact Sonoco today to select which membrane option - Sealed-Safe®, UltraSeal® or Ultrapeel® – is right for you.


Sealed-Safe Membrane Ends

Increase customer delight by using Sonoco Sealed-Safe membrane ends.   Designed specifically for dry products, the membrane creates a hermetic seal that protects your product’s quality and freshness by keeping out oxygen, moisture and aroma.  Sharp edges are eliminated for safer and easier opening.

Sealed-Safe ends can be double seamed on existing equipment with minor modifications. Select diameters include leveling feature, tab or ring-pull and recessed tab. Printing and embossing can be used to showcase your brand. 

Choose from six diameters:
211/65mm, 211 LevelRite/65mm, 307/83mm, 401/99mm, 502/127mm, 603/153mm


Ultraseal® Membrane Ends

Finger cuts from opening a can are a thing of the past with Sonoco’s Ultraseal membrane ends. Lightweight and peelable, your customers will appreciate Ultraseal’s easy, one-piece opening. Ultraseal ends can also be double seamed on existing equipment with minor modifications, and can be printed for increased brand awareness. Suitable for flushing, vacuum or pressure processes, and can be fitted with a valve for coffee applications.

Choose from three diameters:
401/99mm, 502/127mm, 603/153mm


Ultrapeel™ Membrane Closures

Designed specifically for heat-and-eat applications, Sonoco's Ultrapeel membrane closure has a lower opening force than conventional scored convenience ends, making it safer and easier to open for children, older consumers and moms who want to avoid the hassle of a can opener. The Ultrapeel end is designed for batched retorts with overpressure, can survive differential pressure spikes up to 8 psi and can be seamed at high speed on existing equipment with minor modifications.
