Biostimulants: A Special Product with Special Packaging Needs
Illustrated cross section of a GORE® Packaging Vent visualizes the constant pressure equalization that prevents biostimulants packaging from bloating, collapsing or leaking.

GORE® Packaging Vents allow for constant pressure equalization – making them a perfect choice for biostimulants product packaging. 

Liquid biostimulants are an innovative and valuable solution that can help farmers meet increasingly challenging sustainability targets without compromising on yield. What makes biostimulants so great, also makes them particularly challenging for packaging, transportation, and storage: Their organic formulation components contain active ingredients that will ferment and release gases.

When failing to manage the off-gassing process, containers may bloat and ultimately leak or even burst. Wasting precious product this way does not look pretty, nor is it sustainable and it will most likely leave customers dissatisfied.

Transportation adds another layer of complexity beyond the manufacturers control. Bloating or collapsing containers due to rapid changes in temperature or altitude, are not a rare occurrence.

But there is an easy fix.

With GORE® Packaging Vents, you can simply adjust your packaging to minimize all these risks. Our vents reliably and continuously equalize pressure to minimize the potential for leaks and maintain the integrity of containers and their contents.

Did you know: Managing off-gassing safely enables thinner container walls, which can allow for reduction in packaging weight. This way, using GORE® Packaging Vents can add an additional layer of sustainability to your product and your brand – a big plus in times of increasing interest in solutions that are easier on the environment.

How It Works

The Science Behind GORE® Packaging Vents for Biostimulants

GORE® Packaging Vents are specifically designed to meet the needs of biostimulants product packaging. They incorporate a high-performance membrane made of expanded polytetrafluoroethylene (ePTFE), exploiting the unique properties of this material invented by Gore.

Package and transport biostimulants with GORE® Packaging Vents: no bloating, no collapsing, no leaking, no ugly spills.

The microporous nature of ePTFE allows gases to pass through to equalize pressure constantly – keeping the packaging in perfect shape, even when used with highly off-gassing formulations – but it blocks larger substances like liquids, dust and dirt, to prevent leaks or contaminant ingress.

GORE® Packaging Vents continue to vent even after liquid contact, which makes them ideal for use with high-viscosity formulations, like foliar biostimulants. Proven performance with hundreds of millions of GORE® Packaging Vents installed world-wide.


GORE® Packaging Vents: Higher Airflow, Excellent Repellency, No Spills

At Gore, we conduct numerous lab test to make sure our products meet the highest industry standards and satisfy our customers. For example, we test our GORE® Packaging Vents for residual airflow as well as repellency properties with real biostimulants on the market.

Three graphs showing the difference of average residual airflows in l/h at 12 mbar: With GORE® Packaging Vents, the airflow stays consistent over 22 days, while vents of other suppliers ensure sufficient airflow only up to eight days.

A comparison between GORE® Packaging Vents (red) and a standard product (blue): the vent of another supplier leaked just eight days after contact with an amino acid-based biostimulant due to pressure buildup, caused by poor repellency. The GORE D17 SG5 vent's airflow remained higher – even after liquid contact.
