    Chemical containers and packaging frequently experience internal pressure build-up due to temperature fluctuations and chemical vapor generation. This can cause container deformation, leakage of hazardous substances, or safety hazards.

    SST-Porous® Foam PE Venting Seal Liners solve these issues perfectly. Composed of oleophobically modified ePTFE waterproof breathable membrane and Foam PE base material bonded via ultrasonic or hot melt methods, they allow air to pass freely for rapid pressure equalization while blocking liquids, oils, and particles. The foam PE structure provides excellent sealing and cushioning, ensuring reliable performance in harsh chemical environments. Available in various sizes to match different container requirements.

    SST is committed to providing professional venting solutions that enhance container safety, prevent leaks, and extend the service life of chemical packaging.

    Proven Venting Strategies to Improve Electronics’ Reliability

    Watch three expert sessions on-demand

    A Durable and Easy-To-Apply Vent Solution

    STT® Protective Vents Adhesive Series provides:

    Balance pressure

    Balance the pressure difference between the inside and outside of the liquid reservoir to prevent it from denting or swelling.

    Waterproof and dustproof

    It can effectively prevent external dust and pollutants from entering the container and protect the stored liquid from contamination.

    Level 8 oleophobic

    Can effectively prevent greasy liquids from passing through the breathable gasket, thereby reducing the risk of leakage.

    1. Prevent Container Deformation: Pesticides and liquid fertilizers easily generate gas due to chemical reactions or temperature changes during storage and transportation, causing bottle swelling or denting. Foam PE venting seal liners allow gas to escape quickly while maintaining a seal, effectively preventing container deformation and rupture.
    2. Protect Content Purity: The venting liner blocks external dust, microorganisms, and moisture from entering, protecting the purity of agrochemicals and reducing contamination and deterioration risks.
    3. Balance Internal and External Pressure: Temperature or altitude changes cause pressure differentials that can lead to leakage or bursting. Foam PE venting seal liners enable real-time gas exchange to avoid pressure buildup.
    4. Enhance Transportation Safety: Through pressure balancing and leak-proof design, it complies with dangerous goods transportation standards, reducing accident risks and ensuring supply chain safety.

    In summary, Foam PE Venting Seal Liners in agrochemicals and fertilizers packaging effectively prevent container deformation, protect content purity, balance internal and external pressure, and enhance transportation safety, significantly improving packaging reliability and product stability.

    1. Prevent Container Deformation: Household chemicals such as detergents and disinfectants easily generate gas during temperature changes, causing bottle swelling or denting. Foam PE venting seal liners allow gas to escape quickly while maintaining a seal, effectively preventing container deformation and rupture.
    2. Protect Content Purity: The venting liner blocks external dust, microorganisms, and moisture from entering, preserving the purity of household chemicals and extending shelf life.
    3. Balance Internal and External Pressure: Pressure differentials during storage and transportation can cause leakage or deformation. Foam PE venting seal liners enable real-time gas exchange to avoid pressure buildup.
    4. Enhance Usage Safety: Through pressure balancing and leak-proof design, it reduces the risk of accidental leaks, complies with household product safety standards, and improves consumer experience.

    In summary, Foam PE Venting Seal Liners in household chemicals and specialty liquids packaging effectively prevent container deformation, protect content purity, balance internal and external pressure, and enhance usage safety, significantly improving packaging reliability and overall product safety.
