MRP Solutions Ribbed 28-400 Straight Sided Flat Threaded Closure

What this packaging is

Ribbed texture and a flat, straight-sided profile make this 28-400 PP Threaded Closure a workhorse cap that's easy to grip, apply, and seal consistently across high-volume lines. Made in the USA by MRP Solutions, the Ribbed 28-400 Straight Sided Flat Threaded Closure works across an impressive range of categories — lip care, eye care, face moisturizer, body scrub, hair treatment, body lotion, vitamins, and pills. The 28mm diameter with 400 neck finish drops into most standard bottle setups without friction. Available with PCR content for brands with material goals, and compatible with offset print, embossing, heat stamping, and digital print for on-cap branding. At 2,500-unit minimums, it's genuinely accessible for emerging brands testing new SKUs or running limited editions.

Why brands choose this

• Accessible minimums for new SKUs or test runs: At just 2,500 units per order, this closure is genuinely within reach for emerging brands, indie formulators, or anyone launching a limited-edition product — no need to over-commit inventory before a concept is proven.
• One cap, eight categories: The 28-400 neck finish is one of the most widely used standards in personal care and nutraceuticals, meaning this closure integrates cleanly across lip, eye, face, body, hair, and supplement packaging lines — a real efficiency win for brand teams managing broad product ranges.
• Decoration-ready for on-cap branding: Compatible with offset print, embossing, heat stamping, kiss printing, tipping, and digital print, this closure can carry a logo, color, or label detail directly on the cap — a useful brand touchpoint in categories like vitamins and personal care where the closure is often the first thing a consumer sees.
