Specifications
This 38mm (38-400) vented white cap with fine ribbed sides and a smooth top includes foam and HIS liners for high density polyethylene (HDPE). The HIS liner provides a tamper evident seal. The grooved foam liner, which remains in the cap even after the consumer opens the container, continues venting the product throughout the containers usage. Vented caps provide both pressure and vacuum relief to prevent container paneling, bloating and leaking.

Material:

Polypropylene PlasticPolypropylene (PP) is a tough plastic that has excellent chemical resistance. PP is translucent in its natural state but can have a glossy finish when produced with color. Some examples of common products made with PP are dairy and medication containers. Polypropylene is suitable for hot fill applications of up to 205°F and is therefore great for autoclaving. Distortion occurs between 240° to 270° F. It is not recommended for cold or sub-freezing temperatures. The Cary Company has an assortment of polypropylene plastics available for purchase, such as plastic caps and jars, which have a higher tolerance for chemical products. Discover if Polypropylene is appropriate for hot fill application by learning more about What Is Hot Fill Packaging and how it applies to Polypropylene containers.

How do the vents on these caps work?
Once the liner is adhered to the bottle, the small vent in the liner allows for gases to filter out underneath the cap
What is the benefit to a vented cap as opposed to a cap with a standard liner?
The vent helps the container to "breathe" while also preventing bloating, paneling, and leaking. Without a "vent", heat induction liners provide an airtight seal.
What type of applications are recommended with vented caps?
It is recommended to be used with less aggressive formulas such as bleach, dry goods, or powders. If you are not sure if this is the right cap for you, you are welcome to request a sample. This form can be found here
Is it possible to still experiencing bloating/paneling or leaking after using a “vented” liner?
Yes, it is possible. It may that your bottle needs to be fluorinated. Reach out to our sales team for more information. Click here for more details on Fluorination.
