Ribbed 33-400 Straight Sided Flat Child Resistant Threaded Closure

What this packaging is

Child-resistant compliance built into a clean, functional form — the Ribbed 33-400 Straight Sided Flat Child Resistant Threaded Closure from MRP Solutions is a PP closure engineered for pharmaceutical, nutraceutical, and personal care packaging. Designed for containers with a 33-400 neck finish, its ribbed sidewall improves grip, while the flat top surface keeps shelf presence tidy. End uses span vitamins, pill bottles, topical ointments, face moisturizers, body scrubs, and hair treatments. Made in the USA, it supports faster fulfillment and domestic supply chain simplicity. Available with PCR content for brands tracking material sustainability goals. A reliable, compliant closure for regulated and retail-facing product lines alike.

Why brands choose this

• Domestic manufacturing, made-to-order flexibility: Made in the USA with an accessible MOQ of 2,000 units, this closure suits emerging brands, limited-edition SKUs, and test launches without requiring a large upfront inventory commitment.
• Cross-category compliance in one closure: The 33-400 child-resistant design spans pharmaceutical, nutraceutical, and personal care applications — from vitamins and topical ointments to moisturizers and hair treatments — reducing the need for separate closure SKUs across a brand's product range.
• PCR availability supports material sustainability targets: Available with PCR content, this PP closure gives brands a credible path toward reduced virgin plastic use without changing tooling or format — a practical win for sustainability reporting and consumer-facing claims.
