Smooth 100-400 Straight Sided PP Cap, Continuous Thread (CT) Closure

What this packaging is

A clean, straight-sided profile and smooth exterior make this 100-400 PP cap a workhorse closure across a wide range of categories. The Smooth 100-400 Straight Sided PP Cap threads onto any 400-finish container neck, delivering a secure, consistent seal at scale. Decoration flexibility is a genuine strength here — offset print, embossing, heat stamping, and digital print are all on the table, with an extensive color range that covers everything from standard white and black to brand-specific aquas, golds, and purples. Made in the USA, this polypropylene closure suits vitamins, gummies, nut butter, body scrub, hair mask, and pomade packaging.

Why brands choose this

• Decoration options that go beyond a label: Offset print, embossing, heat stamping, and digital print are all compatible with this cap's smooth exterior — giving brand teams the flexibility to carry branding directly on the closure rather than relying on a separate label application.
• Made in the USA, built for domestic supply chains: Produced and warehoused in Plattsburgh, NY, this closure cuts international lead times and simplifies sourcing logistics for brands that need reliable, domestically manufactured components at production scale.
• A format that spans multiple category aisles: The 100-400 straight-sided cap covers a genuinely broad end-use range — vitamins, gummies, nut butter, body scrub, hair gel, pomade, and more. For brand teams ranging multiple SKUs or product lines, a single closure spec that works across categories meaningfully reduces vendor count and component complexity.
