Calaso Smooth 48-400 Straight Sided Flat Threaded Closure

What this packaging is

A clean, flat-top PP closure with serious category range — the Smooth 48-400 Straight Sided Flat Threaded Closure from Calaso fits the standard 48-400 neck finish found across lip care, face moisturizers, body scrubs, hair treatments, body lotions, and even vitamins and supplements. Manufactured in Europe and built from polypropylene with vertical side ridges for easy grip, it delivers both function and a glossy, modern aesthetic. Custom color matching is available, and PCR content can be incorporated for brands with sustainability commitments. With accessible minimums of 1,000 units, this closure works well for emerging brands and limited-edition launches looking for reliable, shelf-ready packaging.

Why brands choose this

• Unusually low MOQ opens the door for small brands: At just 1,000 units, this closure is genuinely accessible for indie brands testing new SKUs, launching limited runs, or building out a product range without overcommitting on inventory — rare for a custom-colorable closure at this neck size.
• One closure, eight product categories: The 48-400 neck finish is one of the most widely used in personal care and wellness, making this closure compatible with containers across lip, eye, face, body, hair, and supplement formats — a real advantage for multi-category brand teams managing components across a full portfolio.
• Sustainability-ready without redesigning the component: PCR content can be incorporated into this PP closure for brands working toward material reduction goals, letting you keep the same sleek silhouette and 48-400 compatibility while meeting retailer sustainability requirements or internal ESG commitments.
