Agricultural chemical packaging needs to be ventilated.

It’s especially critical to use vented agricultural containers for high-offgassing products, and those whose natural variations provoke varying rates of fermentation and gas release:

  • Agricultural liquid fertilizers 
  • Pesticides
  • Biostimulant products 

Without the appropriate vents, agricultural containers could collapse, bulge or leak when exposed to changes in altitude or temperature. Pallets could collapse. Labels could be ruined and as a result important safety information can be potentially illegible. Consumers could be exposed to leaked chemicals, while agricultural packaging manufacturers could experience decreased profits due to lost productivity and unsatisfied customers.

Gore’s packaging vents minimize these risks for even the most highly concentrated chemical formulations, and we provide vents that meet the stringent ADR and DOT standards.



Our portfolio of vents for agricultural products packaging meet stringent ADR and DOT standards, and are designed to reliably protect the integrity of containers that  bear the most challenging contents:

  • biostimulant formulations 
  • liquid fertilizer packaging
  • highly-concentrated chemical formulations
GORE Packaging Vents protect containers of agricultural chemicals from deformation, leaks and label damage

GORE Packaging Vents protect agricultural packaging from deformation, leaks and label damage.

Two ways GORE Packaging Vents protect package integrity

Why Vent?


From manufacturers of liquid chemicals or caps and containers, through transport and storage, to end-users, everyone benefits from effective venting, because it:

  • Safely equalizes pressure differentials that could cause containers of liquid chemicals to deform, leak or burst.
  • Prevents damage to packaging and labeling, and the associated damage to brand reputation.
  • Minimizes the risk of time-consuming and costly efforts to deal with returns, spills or clean-ups due to leaky or damaged containers.

GORE® Packaging Vents minimize all these risks for all types of packaging in agricultural applications. They reliably and continuously equalize pressures, to minimize the potential for leaks and maintain the integrity of containers and their contents.  When container integrity is paramount, GORE Packaging Vents are the solution


The problem  — container deformation that can lead to leaks or bursting — arises when the pressures inside and outside the container are not balanced.

GORE Packaging Vents safely and reliably relieve these imbalances, whatever their source:

    Active Ingredients that Release or Consume Gases

    Unvented container bloating due to off-gassing and collapsing due to oxygen scavenging.

    Without venting, pressure build-ups can cause a container to bloat, leak or burst, while under-pressures can cause container collapse.


    Many chemical formulations include active ingredients that either off-gas (release gases within the container) or scavenge (consume) free oxygen within the container. 

    • Off-gassing builds up pressure within the container.
    • Oxygen scavenging creates an under-pressure within the container.


    Containers Designed to Dispense Liquids

    Without venting that continuously re-balances the internal and external pressures, the dispensing container may collapse.


    In these packages, the dispensing action automatically creates an under-pressure condition within the container, which will happen repeatedly with use.


    Changes in the External Environment

    Sudden or extreme changes in the external environment will accelerate the deformation.


    During shipment or warehousing, changes in the external environment (such as increasing or decreasing temperatures or altitudes) also create pressure imbalances that can deform unvented or poorly-ventilated agricultural containers.




    Packaging of agricultural produce requires special care — as does packaging of agricultural products with active ingredients. In each case, the contents require special protection to reach the end-user undamaged. Gore has a venting solution for all types of materials used for packaging agricultural products, from consumer spray bottles to jerry cans and IBCs.

    The UN Orange Book* recommends venting for any formulation that could cause package deformation. Highly-concentrated pesticides or fertilizers produce higher levels of off-gassing or oxygen-scavenging. Venting protects their packaging from deformation, leaks and label damage.

    Examples of agrochemicals that require venting:

    • Organic/inorganic fertilizers
    • Pesticides
    • Biostimulant formulations
    • Gardening liquids
