Product Structure
Designed for Reliable Induction Sealing and Venting
Our induction vent liners can be configured to match your container material, cap design, filling process and pressure equalization requirements.
1-Piece or 2-Piece Liners
Available with clean-peel, wax-bonded or backing-board structures to suit different cap systems and opening requirements.
PE, PET and Glass Compatibility
Custom heat-seal layers can be selected for HDPE, PET, PP and glass containers based on rim material and sealing conditions.
Laser-Welded ePTFE Membrane
The breathable membrane is integrated into the foil structure to support airflow while helping block liquid entry.
Tamper-Evident Foil Seal
Induction sealing creates a visible foil barrier that supports product integrity and helps reduce leakage risks in transit.
Engineering Advantages
More Than a Standard Induction Seal
Induction vent liners are developed for liquid products that may generate pressure changes during filling, storage, temperature variation or transportation. The combination of foil sealing and breathable membrane technology supports more stable packaging performance.
Stable Heat-Seal Performance
Aluminum foil layers are designed for consistent heat transfer during induction sealing, helping create a secure bond between the liner and container rim.
Chemical-Resistant Venting Options
Hydrophobic and oleophobic ePTFE membrane options are available for oils, surfactants, agrochemicals, acids and other challenging liquid formulations.
Support for Transport Pressure Changes
Controlled venting can help reduce container swelling, paneling and pressure-related packaging issues during storage and global logistics.
Typical Applications
Where Induction Vent Liners Are Used
Agrochemical Packaging
Suitable for pesticide, fertilizer, herbicide and solvent-based agricultural chemical containers.
Industrial Chemicals
For acids, alkalis, oxidizers, cleaning concentrates and other industrial liquid products.
Lubricants and Additives
Used for automotive fluids, fuel additives, engine treatments and solvent-containing products.
Cleaning and Sanitizing Products
Supports packaging for concentrated cleaners, disinfectants, bleach products and institutional chemicals.
