MRP Solutions Smooth 38-400 PP Flip Top Cap

What this packaging is

USA-made and built for the demands of supplement and nutraceutical packaging, the Smooth 38-400 PP Flip Top Cap from MRP Solutions delivers reliable, controlled dispensing for vitamins, pills, and gummies. The polypropylene construction pairs a flat, smooth collar with a single-flap hinge that integrates cleanly into existing 38mm 400-thread neck lines. Six stock colors — white, black, red, green, yellow, and blue — plus custom color options give brand teams real flexibility, and decoration compatibility (offset print, embossing, heat stamp, and more) means this cap can carry your branding without a secondary component. Available with PCR content for brands tracking material reduction goals. A straightforward, dependable closure for supplement brands that want function and shelf presence.

Why brands choose this

• Domestic manufacturing, faster timelines: Made in the USA, this cap cuts lead times and removes customs complexity for domestic supplement and nutraceutical brands — a real advantage when you're working against a launch window or restocking under pressure.
• Decoration-ready for brand differentiation: Compatible with offset print, embossing, heat stamping, tipping, and kiss printing, this cap can carry product identification or brand elements directly on the closure — reducing label reliance and tightening the overall package design.
• PCR content available for sustainability commitments: Available with recycled content included in the polypropylene construction, making it easier for brands with material reduction or sustainability reporting goals to spec a functional closure without switching formats or suppliers.
