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:

    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.

    Active ingredients in chemical packaging applications can off-gas (release gases within the container), or they can scavenge (consume) free oxygen within the container.

    • Off-gassing will build up pressure within the container.
    • Oxygen scavenging will create under-pressure within the container

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

    Unless it is properly vented, industrial fluid packaging that provides a dispensing function is always vulnerable to collapse. That’s because the act of dispensing automatically creates an under-pressure within the container, and that under-pressure recurs with each use.

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

    During distribution or storage, industrial chemical or cleaner packaging is exposed to changes in the external environment. These changes (increasing or decreasing temperatures or altitudes) create pressure imbalances that can cause unvented or inadequately-vented containers to bloat or collapse.



    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

    Discover what else GORE Packaging Vents can do:


    GORE® Packaging Vents perform reliably to minimize risk in a wide variety of chemical packaging applications.


    According to the U.N. Orange Book*, if a dangerous good is vented, no leakages are allowed. Packaging engineers must address this need for leak-proof yet breathable packaging to protect the container and its contents through the whole product life cycle.

    GORE® Packaging Vents can prevent the kind of label or container damage that makes shoppers reject a household cleaner instead of buying it.

    For today’s more highly-concentrated household chemical formulations, venting is increasingly required.  Retail environments offer customers plenty of choices, so they don’t hesitate to reject deformed, leaky or label-damaged packages. Reliable venting is the key to successful packaging and satisfied customers.
