Smooth 40-400 Straight Sided Flat Threaded Closure

What this packaging is

A straight-sided, flat-profile design gives this 40/400 threaded closure a clean, low-height look that works across a wide range of container shapes and branding aesthetics. The Smooth 40-400 Straight Sided Flat Threaded Closure is a polypropylene cap finished in smooth matte white, offering a neutral, decoration-ready surface for labels or printing. Its 40/400 neck finish ensures broad compatibility across jar and bottle formats used in lip balm, eye cream, facial moisturizer, body scrub, hair treatment, and body lotion categories. Manufactured in Europe, it brings reliable quality to brands building cohesive multi-SKU lines. Accessible minimums make it a practical choice for emerging brands or limited-edition runs.

Why brands choose this

• Broad 40/400 compatibility simplifies vendor sourcing: The standard 40/400 neck finish means this closure pairs with a wide range of existing jars and bottles across skincare and body care, so brand teams can standardize on one cap across multiple SKUs rather than sourcing separately for each.
• Accessible minimums built for emerging brands and limited runs: With genuinely low minimums, smaller brands and those testing new formulas can stock this closure without committing to large quantities — a real advantage when validating a new product line or launching a seasonal collection.
• Neutral matte white surface ready for brand decoration: The smooth, straight-sided flat profile provides a clean canvas for labels, screen printing, or hot stamping, making it easy to align this closure with any visual identity across a broad product range from lip balms to hair treatments.
