Smooth 40-400 Straight Sided Flat Threaded Closure

What this packaging is

A straight-sided, flat-top profile gives this 40-400 threaded closure a clean, stackable silhouette that works equally well on minimalist apothecary lines and bold mass-market ranges. Made from polypropylene in a glossy black finish, the Smooth 40-400 Straight Sided Flat Threaded Closure is built around a standard 40/400 neck finish, making it compatible with a wide range of container formats across lip care, eye care, face moisturizers, body scrubs, hair treatments, and body lotions. Manufactured in Europe and available with accessible minimums of just 50 units, it's a practical starting point for emerging brands or limited-edition runs.

Why brands choose this

• Low minimums built for test launches: At just 50 units, this closure is accessible for emerging brands, small-batch development, or limited-edition seasonal launches without committing to large inventory.
• 40/400 neck finish spans an unusually wide range of categories: The standardized thread size pairs with containers across lip, eye, face, hair, and body care — giving brand teams a single closure that works across an entire product range and simplifies vendor management.
• Flat straight-sided geometry supports clean, brand-forward decoration: The smooth exterior and straight walls provide an uninterrupted surface that takes labels, screen printing, and hot stamping cleanly, making it easy to carry brand identity consistently from container to cap.
