Product Description
Providing a bidirectional gas exchange
through a liquid-tight but gas-permeable
membrane. The container is reliably sealed while
allowing the filling substance to “breathe”.
This effectively prevents any “shrinkage” or “panelling”
of the container due to a vacuum or excessive
overpressure.
