Smooth 45-400 Straight Sided PP Cap, Continuous Thread (CT) Closure

What this packaging is

A straight-sided profile and smooth exterior make this 45-400 PP cap a natural fit for decoration-forward packaging. The Smooth 45-400 Straight Sided PP Cap is a continuous thread (CT) closure in polypropylene, sized for standard 45-400 neck finishes across wide-mouth containers. Its flat, cylindrical surface accepts offset printing, heat stamping, embossing, and digital printing with ease. Available in an extensive color range, from white and black to aqua, gold, and multiple greens and purples, color matching is genuinely flexible. Made in the USA in Plattsburgh, NY, this closure suits body scrub, hair mask, pomade, eye cream, spice, and sauce packaging alike.

Why brands choose this

• Built for decoration across multiple print methods: The smooth, straight-sided exterior gives brand teams a clean canvas for offset printing, heat stamping, embossing, and digital printing — all on one closure. That range of compatibility reduces the need to qualify multiple cap SKUs across different decoration workflows.
• Color range that actually covers brand palettes: With options spanning white, black, pearl white, aqua, multiple blues, greens, reds, purples, golds, and yellows, this cap can match or complement nearly any brand color system without requiring a custom color run, which keeps timelines tighter.
• USA manufacturing that simplifies domestic supply chains: Produced and warehoused in Plattsburgh, NY, this closure cuts international lead times and customs complexity for brands sourcing domestically — a real advantage when production schedules are tight or inventory needs to move quickly.
