600833, 600835 38/400 Alto Cap with Vented Liner

Print Friendly, PDF & Email

Alto’s white or black 38/400 thread caps (wad-seal version) with Super Resistant Vent (SRV) grooved back foam liner (Circumvent YC4 grooved back foam liner F-217-30 WC). Gas escapes out the grooves in the liner and the cap thread, so no hole is required. For more information please see this attachment: PSI Circumvent Info

We can insert this vent into 38mm caps for customers, as long as the cap is a wad-seal version as we can not fit a liner to a cone seal cap.

Vent by Performance Systematix Inc, USA.

Venting of caps allows containers to ‘breath’ which stops them blowing out or sucking in. Some products emit gas, which must be allowed to escape or the container will start to bloat and could crack or explode and they are unstable on the shelf. Other products are oxygen scavengers so they cause the sides of the container to suck in (panel) which causes labels to fall off and instability.

For our venting guidelines please click here: Venting Guide 2015 and call us if you have any questions or require samples for testing.

Vented closures must be tested under your specific end use conditions at your own discretion and risk.
