D15 Vented Cap (55.3mm / 55.5mm / 55.8mm) for Agrochemical Packaging | Waterproof Breathable Packaging Closure for Pesticides & Liquid Chemicals

The D15 Vented Cap is a high-performance packaging closure specifically designed for agrochemical, pesticide, fertilizer, and industrial chemical containers. Integrated with a waterproof breathable venting system, the cap effectively balances internal and external pressure while preventing liquid leakage, container deformation, and product contamination.

Available in multiple neck sizes including 55.3mm, 55.5mm, and 55.8mm, the D15 vented cap is manufactured from high-quality HDPE materials and can be paired with PTFE vent membranes to provide exceptional air permeability and waterproof protection. It is widely used for packaging products that generate gas, experience temperature fluctuations, or require pressure equalization during storage and transportation.

For chemical manufacturers, agrochemical formulators, and packaging suppliers, the D15 vented cap offers a reliable solution that enhances transportation safety, extends packaging life, and reduces leakage risks in domestic and international logistics.

Many agrochemical and chemical products face packaging challenges during storage and transportation.

Liquid pesticides, fertilizers, disinfectants, and industrial chemicals often release gases due to temperature changes or chemical reactions. Traditional caps cannot release excess pressure efficiently.

When pressure accumulates inside the bottle, containers may bulge, deform, or even crack during transportation.

Without proper pressure equalization, pressure forces liquid products through sealing surfaces, causing leakage and contamination.

Export shipments often experience significant temperature fluctuations during ocean freight, increasing internal pressure inside chemical containers.

Leaking containers result in damaged packaging, reduced product value, and increased claims from distributors and end users.

The D15 vented cap is engineered to solve pressure management problems while maintaining excellent sealing performance.

• Automatic pressure equalization
• Waterproof and leak-resistant design
• Prevents bottle swelling and deformation
• Reduces transportation-related leakage
• Compatible with agrochemical and chemical packaging
• Suitable for export shipping and long-distance transportation
• High chemical resistance
• Available in multiple colors and custom configurations
• Supports OEM and customized production

By integrating a high-performance vent membrane into the closure system, the cap continuously balances pressure while preventing liquid penetration.

The D15 vented cap is widely used across various industries where pressure equalization is critical.

• Herbicides
• Insecticides
• Fungicides
• Plant growth regulators
• Liquid fertilizers

• Hydrogen peroxide
• Industrial additives
• Cleaning chemicals
• Water treatment chemicals

• Crop protection products
• Concentrated pesticide formulations
• Suspension concentrates (SC)
• Emulsifiable concentrates (EC)

• Laboratory reagents
• Industrial liquids
• Sensitive formulations

The D15 vented cap incorporates a waterproof breathable membrane inside the closure.

Pressure increases inside the container due to temperature changes, altitude variation, or product outgassing.

Air molecules pass through the microporous vent membrane.

The membrane equalizes pressure between the inside and outside of the container.

Liquid, water, dust, and contaminants are blocked from entering the package.

The container remains stable without swelling, leakage, or deformation.

This continuous pressure management process significantly improves package reliability during transportation and storage.
