The PE Laminated PTFE Membrane Liner is a high-performance sealing and venting solution designed for corrosive chemical reagent packaging containers, including laboratory bottles, industrial chemical containers, agrochemical packaging, and high-volatility liquid containers.
This liner combines a polyethylene (PE) support layer with a microporous PTFE membrane, delivering excellent performance in sealing, pressure equalization, leak prevention, and chemical resistance.
During storage and transportation, chemical liquids often generate internal pressure due to temperature changes, chemical reactions, or gas release. This liner allows gas to escape while preventing liquid leakage, helping maintain container integrity and improving packaging safety.
It is an ideal choice for packaging systems that require both airtight sealing and controlled venting, especially for aggressive and sensitive chemical media.
Chemical packaging—especially for corrosive liquids—faces several challenges:
The PE laminated PTFE membrane liner effectively addresses these issues by combining chemical resistance, breathability, and sealing reliability in one integrated structure.
PTFE is highly inert and resistant to a wide range of aggressive chemicals, including acids, alkalis, oxidizers, and solvents.
The microporous PTFE membrane allows gas exchange while blocking liquids, helping prevent leakage while balancing internal pressure.
Reduces risks of container bulging, deformation, or rupture caused by pressure differences during storage and transport.
The PE layer provides structural support and compatibility with bottle caps, while the PTFE layer delivers functional venting performance.
Widely used for packaging:
Available in custom sizes, thicknesses, and structures to match different bottle necks, caps, and application requirements.
Compatible with:
Minimizes leakage risks and improves transportation reliability for hazardous or sensitive chemicals.
Balances internal and external pressure, reducing bulging and collapse issues.
Helps maintain stable internal conditions, protecting chemical composition and quality.
Suitable for international chemical packaging standards and long-distance transportation.
We can recommend the optimal liner structure based on your chemical type, container design, and performance requirements.
Specialized in sealing materials, vent membranes, and functional packaging liners.
Support for OEM/ODM, including size, structure, material combinations, and branding.
Capable of supporting both trial orders and large-volume supply for global customers.
Experienced in chemical packaging, agrochemical packaging, laboratory applications, and industrial container systems.
