Many industrial and consumer container products can become bloated, collapsed or even explode due to unequalized pressure during processing, transportation or storage. Porex vents are designed to enable the container to “breathe” and thereby equalize pressure within the container preventing distortion and damage of the container.
Porex has developed several material selections of porous plastic vents that address industrial and consumer packaging requirements allowing for container integrity. Porex porous polytetrafluoroethylene (PTFE) is a weldable, breathable, leak-resistant material solution for industrial and consumer vented liners and cap closures. It is designed for use with solvent or water-based solutions, granular or powder chemicals, food and beverage, or for use with low surface tension fluids such as oils, detergents, surfactants, and more. Porex polyethylene (PE) and polypropylene (PP) vent materials are also available based on the application temperature, liquid and chemical properties of the material within the container.
