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.
Print Reprint
FILED IN:  Package Type  > 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.
