Smooth 63-400 PP Flip Top Cap

What this packaging is

One-handed dispensing and a wide 63mm opening make this polypropylene flip top cap a go-to closure for high-viscosity liquids. The Smooth 63-400 PP Flip Top Cap from MRP Solutions fits the standard 400 neck finish, giving it broad compatibility across bottles used for pet food, detergent, body wash, shampoo, and lotion. Made in the USA, it ships faster and sidesteps the import headaches that slow down domestic product launches. Decoration options — offset print, embossing, heat stamping, and more — give brands real shelf presence without a secondary vendor. Available with PCR content for brands building toward more sustainable packaging specs.

Why brands choose this

• Made in the USA, ships fast: Domestic production means shorter lead times and no customs delays — a real advantage for brands scaling quickly or managing tight launch windows.
• Broad container compatibility unlocks ranging efficiency: The 63-400 neck finish is one of the most widely used standards in personal care and household categories, so one cap SKU can work across multiple bottle formats — reducing vendor complexity when you're building out a product range.
• PCR content available for sustainability commitments: This cap can be sourced with post-consumer recycled PP content, giving brands a credible material-reduction story that supports ESG goals and increasingly PCR-forward retailer requirements — without switching suppliers.
