What this packaging is

Child-resistant protection built right into a clean, stackable profile — the Ribbed 28-400 Straight Sided Flat Child Resistant Threaded Closure from MRP Solutions delivers both compliance and versatility in one polypropylene cap. Designed for the 28-400 neck finish, it pairs broadly across personal care and nutraceutical containers used for lip care, eye care, face moisturizers, body scrubs, hair treatments, body lotion, and supplement packaging. Made in the USA for faster turnaround and simpler domestic sourcing. Available with PCR content for brands tracking material reduction goals. The ribbed grip, flat top geometry, and multi-decoration compatibility make this closure a practical workhorse for regulated and retail-ready product lines.

Why brands choose this

• USA manufacturing cuts lead times for regulated launches: Made domestically by MRP Solutions, this closure simplifies sourcing logistics and speeds up production timelines — a real advantage when you're working against a compliance deadline or retail window for supplement or personal care products.
• 28-400 compatibility spans an unusually wide product range: One neck finish covering lip, eye, face, body, and nutraceutical categories means your development team can standardize on a single closure spec across multiple SKUs — reducing vendor complexity and streamlining testing across your product range.
• Decoration-ready surface supports brand differentiation at shelf: The flat top and ribbed sidewall support offset print, heat stamping, embossing, kiss printing, and digital print — giving brand teams real flexibility to express identity on a functional component without needing a custom mold.
