Venting of caps allows containers to ‘breathe’ 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 bottles to become unstable.
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.
