Ribbed 89-400 Straight Sided Flat Child Resistant Threaded Closure

What this packaging is

Child-resistant compliance built into a clean, functional design — the Ribbed 89-400 Straight Sided Flat Child Resistant Threaded Closure from MRP Solutions is a polypropylene cap engineered for vitamins, supplements, gummies, pills, and topical ointments. The ribbed exterior gives consumers a confident grip, while the 89-400 neck finish ensures broad container compatibility across the nutraceutical and pharmaceutical categories. Made in the USA, this closure supports faster sourcing and easier compliance for domestic brands. Available with PCR content for brands working toward more sustainable packaging. Customizable with offset print, embossing, heat stamping, and digital print — so even a functional safety cap can carry your brand.

Why brands choose this

• Made in the USA for regulated categories: Domestic manufacturing shortens lead times and simplifies compliance documentation — a real advantage when you're working with FDA-regulated vitamins, supplements, or OTC topicals that can't afford supply chain surprises.
• Decoration-ready for a cap that usually gets ignored: Six customization options — offset print, embossing, heat stamping, tipping, kiss printing, and digital print — mean this closure can carry a logo, lot code, or brand mark, turning a safety requirement into a brand touchpoint.
• PCR content available for sustainability-minded brands: As nutraceutical and supplement brands face growing pressure to reduce virgin plastic use, this closure can be sourced with recycled PP content, giving product developers a credible material story without switching formats or suppliers.
