Ribbed 45-400 Straight Sided Flat Child Resistant Threaded Closure

What this packaging is

Child-resistant by design and grippy by feel, the Ribbed 45-400 Straight Sided Flat Child Resistant Threaded Closure from MRP Solutions is a PP closure engineered for pharmaceutical and nutraceutical packaging. Built to fit the industry-standard 45-400 neck finish, the ribbed exterior improves torque grip while the flat top opens the door for labeling, hot stamp, embossing, kiss print, and digital decoration. Made in the USA, it ships faster and skips the customs headache for domestic brands. PCR content is available for brands building toward lower-virgin-plastic commitments. With accessible minimums for emerging brands or limited-edition runs, it's a practical, compliant cap for vitamins, gummies, pills, and topical ointments.

Why brands choose this

• USA manufacturing cuts lead times and import complexity: Made domestically by MRP Solutions, this closure ships faster and avoids the customs delays that slow down regulated product launches — a real advantage when you're working against retailer or compliance deadlines.
• Flat top unlocks serious decoration real estate: The straight-sided flat profile is compatible with offset print, hot stamp, embossing, kiss print, and digital decoration — giving brands in the crowded supplement and OTC space a clear path to shelf differentiation without switching components.
• Available with PCR content for brands with sustainability targets: As clean-label and eco-conscious positioning grows in the nutraceutical and wellness space, this closure can be sourced with recycled PP content — letting brands reduce virgin plastic use without compromising the child-resistant function or performance specs.
