Case Study: Preventing Agrochemical Bottle Leakage with ePTFE Vent Membrane
How Ventrase improved agrochemical packaging reliability through waterproof breathable membrane technology and pressure equalization solutions.
Customer Challenge
A global agrochemical packaging manufacturer faced leakage risks during storage and international transportation. Changes in temperature, chemical vapor generation and internal pressure fluctuation caused bottle deformation and potential sealing failures.
The packaging required a reliable venting solution that could maintain pressure balance while preventing liquid leakage and protecting the chemical contents.
Problem Analysis & Root Cause
Ventrase engineers evaluated the packaging structure and application environment to identify the main causes behind leakage and deformation problems.
Main Causes Identified
- Temperature changes during transportation and warehouse storage
- Chemical vapor accumulation inside sealed containers
- Pressure imbalance between internal container space and external environment
- Insufficient gas exchange capability of conventional sealing structures
Without controlled pressure release, sealed containers may experience expansion, deformation or leakage during long-term storage and transportation. A breathable venting system provides continuous air exchange while maintaining protection against liquid penetration.
Testing & Engineering Verification
Before selecting the final venting solution, Ventrase engineers evaluated the application requirements including airflow performance, waterproof protection, chemical compatibility and long-term reliability.
The testing process ensured that the selected breathable membrane could release excess pressure while preventing liquid leakage from agrochemical containers.
