Liquid Packaging Challenges
Help Protect Containers Through Storage and Transport
Temperature changes, altitude variation, volatile liquids and gas generation can create pressure differences inside sealed containers. A suitable venting component helps balance internal and external pressure while supporting the overall packaging system.
Reduce Swelling and Paneling
Breathable vent structures can help reduce pressure differences that may contribute to container expansion, collapse or closure stress.
Support Leakage Control
Selected membrane structures can provide airflow while helping maintain a controlled barrier against liquid migration in normal packaging use.
Material Selection by Liquid Type
Membrane, adhesive and liner structures can be reviewed according to liquid chemistry, surfactants, oils, solvents and storage conditions.
Compatible with Multiple Closure Formats
Venting components can be supplied in formats suitable for cap liners, membrane discs, plugs, induction seals and custom closure designs.
Liquid Container Vent Engineering
Designed Around Your Liquid, Container and Closure System
Effective venting depends on the full packaging system. The liquid formula, bottle resin, cap structure, liner seat, headspace, filling temperature and transport conditions should all be considered before choosing a vent format.
Liquid Compatibility Review
Review viscosity, surface tension, surfactants, solvents and other ingredients to identify a suitable membrane and liner structure.
Closure and Container Assessment
Consider bottle type, jerrycan design, cap diameter, liner space, sealing surface and available venting location.
Sample and Testing Support
Sample components can be prepared for airflow, leakage, pressure cycling and application-specific packaging evaluation.

Packaging Vent RFQ
Please prepare the following six details before submitting your inquiry.
- Product or liquid type: What will the container hold?
- Container type and volume: Bottle, jerrycan, drum or IBC?
- Closure details: Cap type, liner type and neck or cap diameter.
- Current packaging issue: Leakage, swelling, paneling, odor or pressure buildup?
- Transport and storage conditions: Temperature range, shipping route or stacking requirements.
- Estimated quantity: Trial quantity, annual volume or expected order quantity.
