Problems We Solve

Containers filled with active chemicals or that are subject to changes in pressure, temperature or altitude need vented closures to allow air to maintain equilibrium while retaining liquids safely inside. Failure to vent the container can result in collapsing, swelling or leaking. PSI manufactures a wide variety of vented closures to reduce or eliminate problems and concerns.

Bloating/Swelling
Under certain conditions, pressure build-up can cause non-vented containers to become bloated or swell. In this state, containers lose their intended shape and may tip over or fall off shelving. The containers may also swell to the point of bursting, causing the package to split open or leak. This results in an undesirable appearance and can be hazardous for those who handle the containers.

Bottle Paneling
Sometimes packaging contracts or collapses during shipping
or storage, creating an unsightly appearance called paneling. Paneling can cause label distortion, stress cracking, or cause the container to fall or tip over, resulting in leaking or spilling. Containers that utilize vented closures maintain their original shape because sterile air can enter the container through the PTFE membrane. The hydrophobic properties of the vented closure keep liquids safely inside while allowing air to pass freely through the membrane.

Leaking
Containers without the appropriate vented liner can be susceptible to leaking. Leaking can create a hazard and an undesirable shelf appearance for potential consumers. Damage may also result to the surrounding environment, creating a potential liability for the retailer. A vented liner from PSI allows gases to escape from the container and reduces the risk of leaking.

Corrosion
Corrosive substances require special packaging due to the gaseous properties created by their chemical composition. If packaging is not properly vented, it may leak and damage the external labeling or the surrounding environment. This can degrade the appearance of the packaging and may create a hazard for people handling the product.

Child-Resistant Applications
Certain substances are dangerous to children and are required
by law to have special packaging and child-resistant caps. PSI has developed two patented products, Circumvent^® and AirFoil^®,
that can convert most child-resistant caps to a vented format based on your particular need. Available in standard sizes 24-53mm.
