Smooth 49-Special Straight Sided Flat Threaded Closure

What this packaging is

A 49mm flat-top threaded closure built to work hard across skincare, lip care, and body care — the Smooth 49-Special Straight Sided Flat Threaded Closure from Calaso brings a clean, glossy finish and a specialized neck fit that pairs reliably with a wide range of wide-mouth containers. Made from polypropylene (PP) and sourced through Calaso's European manufacturing network, this closure carries the design precision and quality consistency that European production is known for. Available with PCR content for brands working toward more sustainable packaging specs. With an MOQ of just 1 unit, it's genuinely accessible for sampling, development, and small-batch launches across moisturizers, scrubs, hair treatments, and beyond.

Why brands choose this

• MOQ of 1 unlocks zero-barrier development: Sample, test, and iterate without minimum order pressure — an MOQ of just 1 unit makes this closure accessible for indie brand launches, reformulations, or limited-edition rollouts where commitment needs to stay low while quality stays high.
• Special neck fit reduces compatibility guesswork: The 49mm special neck finish is engineered for a precise, secure thread engagement — reducing the trial-and-error that typically slows down component sourcing when brands are matching closures to wide-mouth jars across multiple SKUs.
• PCR-compatible PP supports evolving sustainability targets: Available with recycled content incorporated into the PP, this closure gives brand teams a credible path toward reduced virgin plastic use — a growing requirement across skincare and body care retail channels and increasingly a factor in retailer ranging decisions.
