38-400 Black Phenolic Continuous Thread Cap PP (Cone liner)
Black, ribbed, continuous thread cap with 38-400 neck finish and a cone liner. Commonly used for household, cosmetic, Essential oils and other water-based products. Phenolic caps are popular in a wide range of wholesale industries from food, personal care, pet care, household products, industrial products, health and beauty, arts, crafts, hobbies and just about any other market segment. This polypropylene (PP) cap has a high tolerance for heat and is very durable. Cone liners are a good option when a leak proof seal is necessary. Cone liners are essentially wedge shaped LDPE (low density polyethylene) inserts that seals the lip of the container, while providing extra protection. These are recommended for use on glass bottles, but can also work with plastic containers and with liquids that are susceptible to evaporation.
