Smooth 63-400 Straight Sided PP Cap, Continuous Thread (CT) Closure

What this packaging is

A straight-sided profile and smooth exterior make this 63-400 PP cap a natural canvas for decoration — offset print, embossing, heat stamping, and digital print all work cleanly on its surface. The Smooth 63-400 Straight Sided PP Cap is a continuous thread (CT) closure with a 63mm neck diameter and 400 thread finish, giving it broad compatibility across wide-mouth container formats. Made in the USA, this polypropylene closure suits supplements, body scrub, hair care, and pomade packaging. It's available across an extensive color palette, making it easy to align with brand identity right out of the gate.

Why brands choose this

• Decoration-ready surface across four print methods: The smooth, straight-sided exterior supports offset print, embossing, heat stamping, and digital print — giving brand teams real flexibility to decorate on-cap without needing a separate label or sleeve.
• Broad container compatibility for multi-SKU ranging: The 63-400 thread finish is one of the most widely used wide-mouth specs in supplements and personal care, so this cap can cap across multiple container formats and product lines without retooling your sourcing.
• Extensive color palette supports brand differentiation at shelf: With options spanning white, black, pearl white, aqua, pink, multiple blues, greens, reds, purples, and beyond, brands can match or build a color story without custom color minimums slowing them down.
