D17 Vent Cap for Agrochemical Packaging | 55.3–55.8mm Inner Diameter Integrated Breathable Cap

The D17 Vent Cap is an integrated breathable cap designed for agrochemical packaging bottles, especially for liquid fertilizers, pesticides, disinfectants, oxidizing liquids, and other chemical products that may release gas during storage or transportation. Compared with ordinary closed caps, this vented cap helps balance internal and external pressure while reducing the risk of bottle swelling, leakage, deformation, or cap loosening. The cap is available in multiple inner diameter options, including 55.3mm, 55.5mm, and 55.8mm, making it suitable for different bottle neck designs and sealing requirements. With a stable cap structure, customizable colors, and optional breathable membrane configuration, the D17 Vent Cap is a practical packaging solution for agrochemical manufacturers, chemical filling plants, and packaging distributors in the XXX market.

In the agrochemical industry, many liquid products are active, volatile, or sensitive to temperature changes. During storage, long-distance shipping, or exposure to high-temperature environments, the liquid inside the bottle may generate gas or pressure. If a normal sealed cap is used, the internal pressure may continue to increase, causing several packaging risks.

Common problems include bottle swelling, liquid leakage, cap deformation, abnormal pressure release, damaged cartons, and customer complaints after delivery. For export packaging, pressure build-up can be more serious because goods often experience long shipping cycles, temperature changes, stacking pressure, and warehouse storage. These problems not only affect product appearance but may also increase replacement costs and damage brand reputation.

For agrochemical products such as pesticides, liquid fertilizers, disinfectants, bleaching agents, and oxidizing solutions, pressure balance is an important part of packaging safety. A reliable vent cap helps the package breathe while maintaining basic sealing performance, making it more suitable for demanding chemical packaging applications.

Our D17 Vent Cap is developed to provide a stable pressure-balancing solution for agrochemical packaging bottles. The cap can be combined with a breathable membrane structure to allow gas exchange while helping prevent liquid leakage under normal use conditions. This design helps reduce bottle expansion and protects the package during filling, storage, and transportation.

The cap body is suitable for common agrochemical bottle structures with 55.3mm, 55.5mm, and 55.8mm inner diameter options. The product has a consistent weight of approximately 28.5g and a stable structural design for batch production. Multiple colors are available, including natural color, milky white, blue, red, yellow, black, and orange. Custom colors can also be produced according to customer requirements.

For B2B buyers, we can support sample testing, color customization, cap matching, and membrane performance adjustment based on the chemical formula, bottle type, filling volume, storage environment, and target market requirements.

The D17 Vent Cap is mainly used in agrochemical packaging where pressure control is required. It is suitable for pesticide bottles, liquid fertilizer bottles, disinfectant packaging, agricultural chemical containers, cleaning chemical bottles, and other liquid chemical packaging.

Typical application scenarios include:

Agrochemical filling factories that need a safer packaging solution for pressure-sensitive products.

Chemical packaging suppliers that provide customized bottle and cap systems for pesticide or fertilizer brands.

Export packaging projects where products must remain stable during long-distance transportation.

Products that may release gas during storage due to chemical activity, temperature changes, or formula characteristics.

Packaging lines that require a cap with both sealing function and breathable pressure-balancing performance.

The D17 Vent Cap works by combining a cap structure with a breathable venting design. When pressure builds up inside the bottle, gas can pass through the breathable area to help balance the pressure between the inside and outside of the container. This reduces the chance of bottle swelling, cap popping, leakage, or package deformation.

At the same time, the cap is designed to maintain practical sealing performance for agrochemical packaging. The breathable component can be selected according to the customer’s liquid formula and pressure release requirement. For low-viscosity, volatile, corrosive, or active chemical liquids, the membrane structure can be adjusted to achieve better balance between airflow and liquid resistance.

This makes the D17 Vent Cap a more reliable choice than standard non-vented caps for chemical packaging products that require pressure management.

When selecting a D17 Vent Cap, buyers should first confirm the bottle neck size. The available inner diameter options are 55.3±0.3mm, 55.5±0.3mm, and 55.8±0.3mm. Choosing the correct inner diameter helps ensure better cap matching and sealing stability.

Second, confirm the chemical product type. Different liquids may have different venting requirements. For example, liquid fertilizer, pesticide, disinfectant, and oxidizing liquids may require different membrane airflow levels and water pressure resistance.

Third, consider the storage and transportation environment. For export orders, high-temperature areas, container shipping, and long storage periods may require stronger pressure-balancing performance.

Fourth, select the color and appearance. Standard colors include natural, milky white, blue, red, yellow, black, and orange. Custom color production is available for brand identification or product classification.

Finally, sample testing is strongly recommended before mass production. Customers can test cap fit, sealing effect, pressure release performance, chemical compatibility, and packaging line compatibility.

The main function of the D17 Vent Cap is to help balance the internal pressure of agrochemical packaging bottles. It reduces the risk of bottle swelling, leakage, deformation, and cap loosening during storage and transportation.
