Calaso Smooth 40-400 Straight Sided Flat Threaded Closure

What this packaging is

A clean, flat-top profile and glossy finish make this PP closure an easy win for brands that want a polished look without overcomplicating the packaging brief. The Smooth 40-400 Straight Sided Flat Threaded Closure from Calaso fits standard 400 neck containers, making it broadly compatible across lip care, eye treatments, face moisturizers, body scrubs, hair treatments, body lotions, and even vitamins or supplements. Made-to-order with accessible minimums of 1,500 units — genuinely useful for emerging brands or limited-edition runs — and available with PCR content for brands building toward more sustainable material sourcing. A versatile closer that earns its place across a multi-SKU lineup.

Why brands choose this

• Low 1,500-unit minimums unlock real flexibility: At just 1,500 units made-to-order, this closure is genuinely accessible for indie brands testing new SKUs, limited-edition launches, or seasonal ranges — without locking up capital in excess inventory.
• Standard 40-400 neck finish spans an unusually wide category range: Compatible with containers across lip, eye, face, body, hair, and supplement categories, this closure simplifies vendor sourcing for brand teams managing diverse product ranges under one roof.
• PCR content available for brands with material commitments: As clean beauty and sustainable packaging expectations continue to rise, the option to specify PCR content in PP gives procurement and development teams a credible, material-level sustainability story without switching components.
