Ribbed 20-400 Straight Sided Flat Child Resistant Threaded Closure

What this packaging is

Built for regulated and sensitive product categories, the MRP Solutions Ribbed 20-400 Straight Sided Flat Child Resistant Threaded Closure delivers CR compliance without sacrificing decoration versatility. Made from polypropylene in the USA — keeping lead times predictable for domestic brands — this 20-400 neck finish closure features a ribbed grip texture and flat top surface ready for offset print, embossing, heat stamping, or digital print. Available with PCR content for brands tracking material reduction goals. With accessible minimums of 4,900 units, it's a practical fit for emerging brands or limited-edition pharmaceutical, nutraceutical, and personal care launches that can't compromise on safety or shelf presence.

Why brands choose this

• Made in the USA with compliance-ready design: Domestic manufacturing means shorter lead times and simplified logistics — critical when you're working against a regulatory launch window for pharmaceutical, nutraceutical, or topical product lines.
• Decoration-ready flat top spans multiple categories: The flat top surface supports six decoration methods — offset print, embossing, heat stamping, tipping, kiss printing, and digital print — giving brand teams real flexibility across lip care, face moisturizer, body lotion, and beyond without sourcing a different closure per SKU.
• PCR content available for material reduction goals: For brands building sustainability commitments into their packaging specs, this PP closure can be sourced with PCR content — a meaningful option in personal care and pharma-adjacent categories where clean ingredient and material transparency increasingly drive purchasing decisions.
