Ribbed 33-400 Straight Sided Flat Child Resistant Threaded Closure

What this packaging is

Child-resistant and grip-ready, the Ribbed 33-400 Straight Sided Flat Threaded Closure from MRP Solutions is a polypropylene cap built to meet the safety demands of pharmaceutical and nutraceutical packaging while pulling double duty across personal care. The ribbed exterior makes it easy to open and close, and the flat top keeps the profile clean and decoration-friendly — compatible with embossing, heat stamping, kiss printing, and digital print. Made in the USA, which means faster turnaround and simpler sourcing for domestic brands. Available with PCR content for brands with material goals. A solid, compliant cap for vitamins, body lotion, fragrance, face moisturizer, and more.

Why brands choose this

• USA-made with decoration versatility built in: Manufactured domestically for faster lead times and easier logistics, this closure also supports embossing, heat stamping, kiss printing, and digital print — giving brand teams real customization options without adding vendor complexity.
• CR compliance across two distinct markets: Child-resistant functionality means this closure meets safety requirements for pharmaceutical and nutraceutical applications, while its clean flat-top profile and ribbed grip translate just as well to personal care shelves — a genuine dual-market asset for brand developers ranging across categories.
• PCR content available for brands with sustainability targets: This closure can be sourced with recycled polypropylene content, giving brands a credible material reduction story without switching formats or suppliers — increasingly relevant as retail partners and consumers push for measurable packaging progress.
