Smooth 63-400 Child-Resistant Threaded Closure

What this packaging is

Child-resistant compliance meets everyday versatility in this USA-made polypropylene closure from MRP Solutions. The Smooth 63-400 Child-Resistant Threaded Closure is a flat-top, straight-sided PP cap engineered for the 63-400 neck finish — one of the most widely used dimensions across pharmaceutical, nutraceutical, and personal care packaging. Built for restricted-access applications like vitamins, topical ointments, face moisturizers, and body scrubs, it supports regulatory compliance without sacrificing range. Domestic manufacturing keeps lead times tight. Available with PCR content for brands with material goals. An MOQ of 600 units makes it genuinely accessible for emerging brands or limited-edition runs. Decoration-ready with five customization options for brand expression.

Why brands choose this

• Compliance-ready at an uncommonly low MOQ: At just 600 units per order, this child-resistant closure is one of the most accessible CR cap options available — letting emerging brands, niche nutraceuticals, and limited-edition personal care lines meet safety compliance requirements without overcommitting on inventory.
• Five decoration paths on a compliance-driven component: Embossing, heat stamping, tipping, kiss printing, and digital print are all on the table — rare for a CR closure in this category. Brands don't have to choose between regulatory function and shelf presence, which matters as wellness and personal care packaging gets increasingly brand-forward.
• USA manufacturing cuts lead time across a broad end-use range: Made domestically by MRP Solutions, this closure is a low-friction sourcing option for brands packaging vitamins, topicals, body lotion, hair treatments, and more — all under one SKU. Add optional PCR content and you've got a compliance component that can also support a brand's material reduction story.
