Smooth 83-445 Straight Sided PP Cap, Continuous Thread (CT) Closure, Stacking, Outer Stacking Ring

What this packaging is

Built for high-volume operations, the Smooth 83-445 Straight Sided PP Cap features an outer stacking ring that keeps closures organized and efficient through filling lines, storage, and transport. This continuous thread (CT) closure fits 83mm neck finishes with a 445 thread finish and is made from polypropylene in the USA, giving domestic brands a reliable, fast-to-source option. Available in a broad color range spanning white, black, aqua, pink, gold, and more, with offset print, embossing, heat stamping, and digital print compatibility. Well-matched for vitamins, gummies, body scrub, hair gel, pomade, and similar categories where a clean, stackable cap closure does serious operational work.

Why brands choose this

• Outer stacking ring built for operational scale: The integrated stacking ring isn't decorative — it's a functional design detail that keeps caps aligned on automated filling lines and reduces storage footprint in high-volume warehouse environments, directly cutting handling time and the risk of cap jams.
• Made in the USA for faster, simpler sourcing: Domestic production means shorter lead times, no customs friction, and tighter quality control for brands running lean or scaling quickly — a real advantage when you're managing high-SKU supplement or personal care lines.
• Broad color range plus four decoration methods: With options spanning aqua, pink, gold, black, and more — plus offset print, embossing, heat stamping, and digital print — brand teams can achieve strong visual differentiation across product lines without switching suppliers or components.
