Polypropylene PlasticPolypropylene (PP) is a tough plastic that has good 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 165°F and is therefore great for autoclaving. 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.

What’s the difference between pictorial and push down & turn child resistant caps?
The difference between the two of these caps is that push down & turn child resistant caps have different emboss directions on the top of the cap. Both require the same method of opening.
What industries use this push down & turn child resistant cap?
In the highly regulated pharmaceutical market, reliable child resistant closures are essential. These caps are also ideal for automotive, household chemicals, nutraceuticals, and pharmaceutical industries.
What kind of cap liners are compatible with push down & turn child resistant caps?
Liner options include vented, 3-ply foam (F217), foam, induction (HIS), LDPE and pressure sensitive.
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.
