Choose the right Closure for your application

THERMOSET & PHENOLIC CAPS - These caps are known for providing the widest range of chemical compatibility and for being the most temperature tolerant of plastic closures. They also provide the most consistent adherence to close dimensional tolerances. Ideal for pharmaceutical applications.

METAL CAPS - Metal caps are sturdy and unbreakable with the widest range of temperature tolerances. Metal caps are great for industrial and food applications.

POLYPROPYLENE CAPS - Polypropylene caps are known for good impact strength, cost effectiveness, and pliability.

Choose the Lining System that best fits your product or sample application

TEFLON® LINED CAPS - Foam backed Teflon® PTFE liners resist attack from virtually all chemicals at room temperature and provides resilience for a tight seal. The color green easily identifies the teflon liner system. Available in Thermoset and Phenolic caps.

PULP/VINYL LINED CAPS - Phenolic caps with pulp and vinyl liners are perfect for general use. The liner is made of a vinyl coating applied to high density polyethylene coated paper and then it is laminated to pulpboard. This general purpose liner is commonly used for food, beverage, medical and chemical applications packed at less than 120° F. Available in Phenolic caps.

POLSYSEAL CONE LINED CAPS - These caps form an exceptionally tight seal and offer a good chemical barrier. This liner molds itself around the sealing areas of the finish as the cap is screwed on, virtually eliminating leakage, evaporation, contamination, binding and backing off. Available in Phenolic caps.

.030 SOLID POLYETHYLENE LINED CAPS - Caps with solid PE liners offer good chemical resistance and low moisture vapor transmission rate. Because this lining system is paperless, your samples will not be contaminated with fiber or paper particles from the closure. Available in Phenolic caps.

White Rubber LINED CAPS - Black phenolic caps with White Rubber liners are autoclavable. This liner is FDA approved for food and pharmaceutical applications. Excellent properties of resilience, resistance to moisture vapor and relatively low gas transmission. Also widely used for packaging injectables. Great for culture work. They also provide the most consistent adherence to close dimensional tolerances. Available in Phenolic caps.

ALUMINUM FOIL LINED CAPS - These caps are typically used for food applications. Free of odor and taste problems. Also can be used for non-acid, non-alkaline products. Available in Phenolic and Metal caps.

PLASTISOL LINED CAPS - Metal caps with a Plastisol liner offer excellent resistance to mild acids as in food products.

LINERLESS CAPS - Linerless polypropylene closures are available in white or black. These caps are autoclavable and are suitable for many dry products.
