Often used for substances containing chemicals or essential oils, phenolic caps are a good way to seal bottles, jars, or vials to keep your product safe and in its original condition. These caps are preferred for use in the pharmaceutical industry as they are chemically inert and will not be affected by any corrosive or otherwise harmful substances. When you buy phenolic caps in bulk, you can be sure that your product will stay safe from packaging to the consumer, while offering both style and functionality.
Unlike some other types of plastic caps used in packaging, plastic phenolic caps are heat-resistant up to 428 degrees Fahrenheit (220 degrees Celsius), so they help protect the contents from deteriorating or changing in color, texture, or smell. This is especially important in materials such as essential oils, perfumes, and creams, as well as more active items like nail polish remover and other acids and chemicals. This resistance makes phenolic caps a good choice in a variety of settings.
There are several types of liners available for phenolic screw caps, so once you've chosen the color, size, and style of cap, you can select the liner that is best suited to your product. Foam liners are useful for food or drug items, and cardboard liners can be paired with threaded caps to top jars of personal care products. Polycone liners are oil-resistant and create a tight seal to prevent leaks while preventing air and moisture from entering the containers. These liners are important in the preservation of bottled beer, alcohol, and wine.
