Packaging vents equalize pressure to prevent distortion or damage
Multiple complications can arise when industrial containers are processed, transported, and stored. Packaging can become bloated, collapse or even explode due to unequal pressure.
Our weldable, breathable, leak-resistant material is an ideal solution for pressure vents for many types of industrial containers. Engineered to exact closure specifications, our packaging/container vents feature POREX Virtek® material, which enables a constant controlled vent rate while retaining and safeguarding container contents. Container manufacturers trust POREX® vents to enable their containers to “breathe,” thereby equalizing pressure to prevent distortion or damage.
POREX Virtek vent material addresses industrial packaging requirements to allow container integrity throughout the transportation and storage process. Designed for use with solvent or water-based solutions; granular or powder chemicals; foods or beverages, and low surface tension fluids such as oils, detergents, and surfactants, our cap and closure vents.
