Jar Caps

Spectrum Jar Caps are injection-molded closures for any standard Straight and Round Base Jars. They are available in stock natural and white, but can be custom colored or decorated as required.

Our selection of stock liner materials includes foam, pulp/polyethylene, and SA66 all in .030-inch and .040-inch thicknesses. Custom liners such as tamper-resistant, pressure-sensitive, and induction seals are also available by special order; however, any custom lining request can be fully investigated and quoted.

Spectrum assures its customers of top-quality products with prime virgin materials, advanced, fully automated injection-molding equipment, the latest technology in injection molds, and fully integrated quality control capable of meeting the most exacting tolerances. The result: a quality product at a competitive price, delivered on-time.
