W. L. Gore & Associates, Inc : Packaging vents for liquid fertilizers
GORE™ Packaging Vents from W. L. Gore & Associates, Inc. prevent leakage in liquid fertilizer containers.
The vents equalize pressure caused by liquid fertilizer formulations
which contain active ingredients that cause containers to collapse or
bloat during altitude, temperature or climate changes. The vents
protect the container and its contents because the gas-permeable,
microporous expanded polytetrafluoroethylene (ePTFE) membrane used in
the vents’ construction repels liquid fertilizer formulations while
allowing air to pass through freely. The vents eliminate the need for
increasing headspace in the container or increasing container wall
thickness. A container’s weight can therefore be reduced, reducing
shipping and recycling costs.
