Specifications

This conical shape provides an excellent seal across the top of the container and also seals across the inside diameter. The liner is constructed of low-density polyethylene (LDPE) plastic which offers superior torque retention. Use it to bottle liquids such as essential oil and liquids that are susceptible to evaporation.

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.
