Smooth 24-400 Round PP Flip Top Cap

What this packaging is

A 24-400 neck finish and 4mm orifice make this flip-top cap a precise, controlled-dispensing closure for high-turnover personal care and household formats. The Smooth 24-400 Round PP Flip Top Cap is a compact polypropylene closure — 0.93 inches tall, 1.27 inches in diameter — that snaps cleanly onto a wide range of standard bottles. Its flip-top mechanism keeps product flow consistent across rinse-off and leave-on applications alike, from shampoo and body wash to face cleanser, hand soap, and dish soap. Custom color matching and hot stamping support brand differentiation on shelf, and PCR content is available for brands with sustainability commitments.

Why brands choose this

• Broad 24-400 compatibility cuts sourcing complexity: The standard 24-400 neck finish fits a wide range of bottles already in circulation, so brand teams can adopt this cap without retooling or requalifying their container lineup — a real advantage when ranging across multiple SKUs or categories.
• Controlled 4mm orifice suits high-use rinse-off and leave-on formats: The flip-top mechanism paired with a 4mm dispensing orifice gives consumers consistent, mess-free doses across fast-moving formats like shampoo, conditioner, body wash, and hand soap — reducing product waste and supporting a cleaner in-shower or at-sink experience.
• PCR content available for brands with material reduction goals: As retailers and consumers apply more pressure on sustainable packaging commitments, the option to incorporate PCR content into this PP cap gives brand teams a credible, material-specific sustainability story without switching to a different closure format.
