Phenolic Lids

Phenolic lids are closures made from phenolic resin, a dense, heat-resistant material that gives these caps a distinctive vintage aesthetic and strong chemical resistance. They are commonly used on glass apothecary bottles, essential oil packaging, specialty food containers, and laboratory bottles, and are popular in the pharmaceutical, aromatherapy, and artisan product industries. Phenolic caps pair particularly well with Boston round glass bottles and are a go-to choice when a classic, professional look is part of the brand identity.
