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® or Ultraseal® – is right for you.
