Aluminum Foil / Foam Vent Liner for Chemical & Daily Use Packaging

Reliable Breathable Sealing Solution for Disinfectant, Drain Cleaner, Pesticide and Household Chemical Caps

Our Aluminum Foil / Foam Vent Liner is designed for chemical and daily-use liquid packaging that requires both secure sealing and controlled venting. It is widely used in disinfectant bottles, drain cleaner containers, pesticide bottles, bleach packaging, detergent caps, and other daily chemical closures.

This vent liner helps balance internal and external pressure inside the container while reducing leakage risks during storage and transportation. It is an ideal sealing solution for packaging products that may generate gas, release pressure, or require breathable performance without compromising safety.

Product Description

The Aluminum Foil / Foam Vent Liner is a high-performance cap liner specially developed for chemical and household liquid packaging. It combines the advantages of sealing, venting, leakage prevention, and pressure equalization, making it suitable for products such as disinfectants, drain cleaners, pesticides, agricultural chemicals, detergents, and other daily-use liquids.

Compared with ordinary cap liners, this breathable liner helps prevent packaging problems caused by internal pressure buildup, such as bottle swelling, leakage, deformation, and transportation risk. The aluminum foil and foam structure provides stable sealing support, while the venting function helps maintain package integrity in demanding filling and storage conditions.

This product is suitable for a wide range of plastic bottle caps and chemical packaging closures, and can be customized according to cap size, bottle type, and end-use requirements.
