Black, smooth, continuous thread cap with 58-400 neck finish with a pressure sensitive liner. Commonly used for food items, lotion, soaps, creams, and personal care items. Continuous thread 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. Similar to a foam liner, pressure sensitive liners have adhesive on one side, and are designed to stick to the rim of the container. The adhesive becomes activated when the container is closed, and pressure is applied to the cap. Pressure sensitive liners provide an extra level of protection in sealing directly to the rim of the container. Although they are not tamper evident, and do not work well with liquids, they can work with creams and sauces. Not recommended for essential oils.
