Idealpak Smooth 68-400 Continuous Thread PP Flat Cap

What this packaging is

A wide 68-400 neck finish in a flat, straight-sided profile gives this cap a clean, low-geometry look that works across a broad range of jar formats. The Smooth 68-400 Continuous Thread PP Flat Cap is made from polypropylene — lightweight at 9.6g, durable, and compatible with body butter, body scrub, hair mask, pomade, hair gel, and face mask packaging. Silk screen printing and heat stamping support on-pack branding without secondary labeling steps. Available with PCR content for brands with material goals. At 2.76 inches in diameter, it's a practical, brand-ready closure for thick-formula personal care products that need a secure, easy-open lid.

Why brands choose this

• Multi-category compatibility across personal care and wellness: The 68-400 thread size covers a wide range of jar formats used in body, hair, and face care — from pomade to hair mask to body butter — giving brand teams one closure that ranges across an entire product line and simplifies vendor SKU management.
• On-pack decoration without extra steps: Silk screen printing and heat stamping compatibility means branding lives directly on the cap, eliminating the need for a separate label application process and keeping the finished package looking intentional and clean on shelf.
• PCR content available for brands with material reduction goals: The Smooth 68-400 can be sourced with recycled PP content, giving brands a credible, material-level sustainability story that goes beyond vague claims and supports commitments to reducing virgin plastic in packaging.
