Ribbed 38-400 Straight Sided Flat Threaded Closure

What this packaging is

Ribbed grip, flat profile, and a 38-400 neck finish that plays well with a wide range of containers — the Ribbed 38-400 Straight Sided Flat Threaded Closure from MRP Solutions is a workhorse PP cap built for both beauty and pharmaceutical applications. Made in the USA, which means faster turnaround and no customs headaches for domestic brands. The ribbed exterior makes it easy to open and close, the flat top stacks cleanly on shelf, and the 38mm diameter fits standard 400-neck bottles used across lip care, eye cream, face moisturizer, body scrub, hair treatment, body lotion, and supplement packaging. Available with PCR content for brands with sustainability commitments, and compatible with offset print, embossing, heat stamping, and digital print. A reliable, decoration-ready closure for brands that want consistency across a full product range.

Why brands choose this

• Made in the USA with real supply chain upside: Domestic manufacturing means shorter lead times, no import delays, and simpler logistics — a practical advantage for brands managing tight launch windows or frequent reorders across multiple SKUs.
• Spans beauty and supplements with one cap: The 38-400 neck finish is a category crossover workhorse — equally at home on a lip balm jar, an eye cream pot, a body lotion bottle, or a supplement container, giving multi-category brand teams a single closure solution that ranges across their full lineup.
• Available with PCR content for brands with material goals: This closure can be sourced with post-consumer recycled PP for brands building toward sustainability commitments — a specific, credible claim that supports cleaner product stories without compromising the functional performance of the cap.
