The Monomaterial Wood 70-400 WOODRING™ Threaded Closure by mPackting is a game-changing sustainable packaging solution, designed for wide-mouth jars in premium personal care and wellness products. This closure is fully customizable and can be formed to match your exact brand vision and is available in a range of FSC-Certified woods including Ash, Beech, Mahogany and more. Engineered for 70-400 neck finishes, this large-format threaded cap features a straight-sided, flat-profile aesthetic that delivers a clean, modern look while enhancing the tactile feel of natural wood.

Part of mPackting’s exclusive WOODRING™ collection, this closure utilizes a patented internal threading system cut directly into the wood—eliminating the need for any plastic inserts, liners, or adhesives. The result is a true monomaterial closure that is 100% bio-based and fully recyclable. This not only simplifies end-of-life disposal but also supports circular design strategies, making it ideal for brands focused on zero-waste, clean beauty, or refillable systems.

Manufactured locally in Italy and the USA, the 70mm WOODRING™ closure helps reduce carbon emissions while ensuring consistent craftsmanship. It can be finished in Spray Varnishing, Oil Finishing, or Glossy coatings to highlight the wood’s natural character. Decoration options such as Laser Engraving, Silk Screen Print, Heat Stamping, Spray Coating, and Embossing enable premium branding applications. With a minimum order quantity of 25,000 units and an 8–10 week production lead time, the Monomaterial Wood 70-400 WOODRING™ Threaded Closure offers brands a high-impact, plastic-free solution for sustainable packaging at scale.
