Idealpak Ribbed 89-400 Straight Sided Flat Cap

What this packaging is

Ribbed texture and a secure 89-400 threaded closure make this flat cap a reliable workhorse for wide-mouth jar applications across wellness and personal care. The Ribbed 89-400 Straight Sided Flat Cap is built from polypropylene in a low-profile 0.61" height and 3.66" diameter — a well-matched footprint for high-volume formats like protein powder, vitamins, gummies, body scrubs, and hair masks. Available in matte or glossy finishes with silk screen printing, heat stamping, and embossing compatibility, it gives brand teams real decorating flexibility. PCR content can be incorporated for brands with material reduction commitments. A practical, brand-ready closure for supplement and body care lines.

Why brands choose this

• Decoration versatility that works across brand aesthetics: Compatible with silk screen printing, heat stamping, and embossing — and available in both matte and glossy finishes — this cap gives brand and design teams genuine flexibility to align packaging with visual identity without sourcing a custom component.
• Format fit across a broad wellness and personal care range: The 89-400 thread and 3.66" diameter are dialed in for wide-mouth jars, making this cap a natural fit for protein powders, vitamins, gummies, body scrubs, body butter, and hair masks — a spanning format advantage for brands that range across supplement and body care SKUs.
• PCR-compatible construction for brands with sustainability targets: Polypropylene construction can be specified with PCR content, giving brands the option to reduce virgin plastic use and support material reduction commitments — a meaningful differentiator as clean formulation brands increasingly extend sustainability goals to packaging.
