Our Waterproof Breathable Valve, also known as a Snap-In Vent Plug, is specially designed for chemical and agrochemical packaging containers. It helps packaging systems safely release internal pressure caused by temperature changes, altitude variation, filling reactions, and gas generation, while effectively preventing liquid leakage, contamination, and container deformation.

This vent valve uses a high-performance PTFE/PO non-woven membrane with oleophobic and hydrophobic properties, making it an ideal solution for demanding packaging environments involving bleacher, disinfectant, amino acid solutions, agrochemicals, and liquid fertilizers.

For manufacturers and buyers in the agrochemical packaging market, this waterproof breathable valve improves package reliability, reduces leakage risk during transportation and storage, and supports safer venting performance for chemical containers.

Chemical and agrochemical liquids often create internal pressure inside packaging containers during storage and transportation. If the pressure cannot be released in time, the container may swell, deform, leak, or even fail, especially in environments with fluctuating temperatures or long-distance shipping conditions.

Our Snap-In Waterproof Breathable Valve is engineered to solve this problem. The valve allows gas to pass through the membrane while blocking water, liquid chemicals, dust, and external contaminants from entering the package. Its HDPE plug body and PTFE/PO membrane structure provide dependable mechanical fit, chemical compatibility, and long-term venting stability.

This product is widely used in agrochemical bottles, pesticide containers, liquid fertilizer packaging, cleaning chemical bottles, and industrial chemical caps where pressure equalization and leak prevention are critical.

Releases internal pressure in chemical containers to help prevent swelling, deformation, paneling, and leakage.

Allows air exchange while blocking water ingress, helping protect the package in harsh logistics and storage conditions.

The PTFE/PO non-woven membrane provides both oil resistance and water resistance, making it suitable for demanding chemical packaging applications.

Helps reduce leakage risks caused by pressure build-up, especially during transportation, stacking, and temperature changes.

The snap-in structure is convenient for integration into caps and packaging systems, supporting practical assembly in industrial production.

With moisture vapor transmission >5000 g/m²/24h, the valve supports effective venting performance while maintaining package protection.

Designed to perform in a wide operating temperature range from -40°C to 125°C, suitable for storage and use in challenging environments.

The product meets RoHS requirements and is PFOA & PFOS free, supporting environmentally conscious packaging projects.

This waterproof breathable valve is suitable for:

• Agrochemical packaging
• Pesticide bottles
• Liquid fertilizer containers
• Disinfectant packaging
• Bleacher containers
• Amino acid solution packaging
• Agricultural chemical caps
• Chemical storage bottles
• Industrial liquid packaging
• Breathable closures for corrosive or active liquid products

Agrochemical and chemical liquids may release gas or create pressure differences due to:

• Temperature fluctuation
• Altitude changes during transportation
• Chemical activity inside the container
• Filling and sealing conditions
• Long-term storage

Without a proper venting solution, packaging may experience:

• Container bulging
• Sidewall deformation
• Cap leakage
• Seal failure
• Product loss
• Transport risk

A high-quality waterproof breathable valve helps maintain packaging integrity by balancing internal and external pressure while keeping liquid and contaminants out.

This valve is specifically developed for packaging applications involving chemical liquids and agricultural formulations.

The membrane combines oleophobic and hydrophobic properties, making it suitable for packaging environments where ordinary venting materials may fail.

With a typical air flow rate of 900 ml/min @ 7KPa, the valve provides dependable breathability for pressure management.

With water entry pressure ≥90 KPa (30 sec), the product offers strong liquid barrier performance.

Designed to support high protection levels for demanding packaging and industrial environments.

Reliable from -40°C to 125°C, suitable for diverse climates and transportation conditions.

Complies with RoHS requirements and is free from PFOA and PFOS, supporting international market expectations.
