Ribbed 70-400 Straight Sided Flat Threaded Closure

What this packaging is

Ribbed aluminum construction sets this closure apart before a brand even reaches the shelf. The Ribbed 70-400 Straight Sided Flat Threaded Closure from Calaso is a silver aluminum screw cap engineered for 70-400 neck finishes, delivering a secure, precise fit across a wide range of containers. The ribbed sidewall improves grip without sacrificing the clean, flat-top silhouette that reads as premium on-shelf. It's a natural fit for body lotion, face moisturizer, eye treatments, lip care, hair treatments, vitamins, and body scrub formats. European-manufactured to tight tolerances, this closure brings a polished, professional finish to any brand looking to elevate everyday packaging into something worth noticing.

Why brands choose this

• European manufacturing meets tight-tolerance quality: Produced in the Netherlands by Calaso, a specialist in glass and closure components, this cap reflects the design precision and material integrity that European manufacturing is known for — a reassuring signal for brands where quality consistency is non-negotiable.
• Unusually accessible minimums for a metal closure: With an MOQ of just 50 units, this aluminum closure is genuinely rare in the metal packaging space — perfect for emerging brands, limited-edition launches, or product developers who want to test a premium aluminum finish before scaling up.
• Wide category versatility simplifies range development: A single closure spec that works across body care, facial skincare, lip, hair, and wellness formats like vitamins and pills means brand teams can standardize on one component across an entire product line, cutting supplier complexity and speeding up development timelines.
