The core product line includes porous PTFE  vents with applications in the chemical packaging, electronics, and medical industries

PorVent® has partnered with Porex Corporation, USA to source advanced sintered PTFE material enabling it to offer industry leading solutions



Failures of chemical containers (leakage or de-shaping) can be attributed to a variety of factors such as – changes in ambient temperature or altitude during transportation, chemicals inside the container releasing gases or consuming oxygen, etc.

This results in

Deformation of the chemical containers results in reduced packaging performance, leakage, financial loss to the company due to replacement and messy clean ups, reduction of content shelf life and loss of brand reputation.

Our Solution

PorVent PTFE vents are made from a liquid repellent breathable membrane that can be incorporated into your packaging.

Key Features:

Prevents contents of container from leaking

Lowers internal pressure so packaging weight can be reduced

Lower packaging weight leads to cost savings in packaging and transport


Core Product Function:

Allows bi-directional exchange of air

Dissipates heat

Blocks entry of contaminants and moisture
