Product Features
Simple Installation, Controlled Venting
Pressure sensitive vent liners are suitable for packaging lines that need a practical venting solution without adding induction sealing equipment or changing the existing capping process.
Torque-Activated Adhesion
The pressure-sensitive layer adheres to compatible container rims when the cap is applied with suitable capping torque.
No Induction Sealer Required
A practical choice for pilot runs, small-batch filling, multi-SKU packaging and facilities without heat-induction equipment.
Custom Airflow Options
Membrane airflow can be selected according to container volume, expected gas generation, storage conditions and transport requirements.
ePTFE Liquid Barrier
Hydrophobic and oleophobic membrane options help resist liquid splash, moisture and low-surface-tension formulations.
Engineering Advantages
Designed for Flexible Packaging Operations
Pressure sensitive vent liners provide a simple alternative when a package needs breathable performance but the production line does not use induction sealing. Proper bottle-rim flatness, cap torque and adhesive compatibility are important for reliable results.
Compatible with Common Containers
Adhesive structures can be evaluated for HDPE, PET and glass containers based on rim finish, cap design and product formulation.
Localized Membrane Venting
The ePTFE vent area is integrated into the liner structure to support gas exchange while preserving the adhesive contact area.
Suitable for Validation Projects
Pre-cut samples can support packaging trials before larger-scale production or a future transition to induction-sealed liner formats.
Typical Applications
Where Pressure Sensitive Vent Liners Are Used
Nutritional Powders
For vitamin, enzyme, sports nutrition and supplement products that may require controlled pressure equalization.
Bio-Agro Products
Suitable for microbial nutrients, organic plant extracts and selected agricultural formulations with mild gas release.
Cosmetics and Personal Care
For creams, herbal formulations and personal-care packaging exposed to temperature or pressure changes in transit.
Liquid Fertilizers
A practical liner option for retail lawn and garden products where equipment-free application is preferred.
Wellness Products
Can support packaging for natural extracts, home-care formulations and selected wellness products.
Pilot Batch Packaging
Useful for product trials and smaller packaging runs before investing in fully automated sealing processes.
