Product Description
Natural & Synthetic Cork Stoppers for Spirits, 22.5mm, Airtight Seal for Liquor
Product Overview

Our range of stoppers—available in both natural and synthetic cork options—is designed for spirits and various types of liquor bottles, offering a traditional yet reliable sealing solution.

Natural cork is the preferred choice for spirits intended for aging, as it allows the liquid to "breathe" and develop richer flavor profiles over time. Synthetic corks provide a reliable seal without imparting any off-flavors or unwanted aromas to the spirit.

Both types of stoppers ensure a secure, leak-proof seal, preserving the quality of the spirit and preventing evaporation. We offer comprehensive customization services including laser printing, custom branding on the stopper top, and a variety of quality grades to meet diverse aging requirements and price points.

Applications
  • Commercial Distilleries & Wine Estates: Large and mid-scale producers requiring reliable, food-grade closures for premium aging lines and consumer-ready releases.
  • OEM/ODM Beverage Bottling & Co-Packing Plants: Factories requiring high-consistency synthetic stoppers to maximize throughput on automated packaging machinery.
  • Industrial Packaging Wholesalers & Distributors: B2B distributors seeking to offer complete, bundled solutions (cork-finish glass bottles + matching straight stoppers + heat shrink capsules).
  • Artisanal Spirit Craft Brands: Specialty distilleries creating limited-edition runs that require premium laser-branded wood corks to convey craft authenticity.
Cork stoppers in various industrial and craft applications
Important Precautions
Precision Bore Matching (Neck vs. Cork Diameter): Cylindrical straight stoppers rely on compression. A cork diameter of 21mm or 22mm is standard for a bottle neck with an 18.5mm inner bore. If the stopper is too large, it may crease or fail to insert; if too small, it will leak. Please provide your bottle's neck technical drawing for our engineers to recommend the exact stopper diameter.
Moisture Control for Natural Wood Storage: Natural wood corks are sensitive to humidity. Bulk inventory must be stored in a dry, temperature-controlled warehouse (relative humidity 50%-70%, temperature 15°C-25°C). Excessive humidity can lead to mold development, while extreme dryness will shrink the wood, compromising its structural elasticity.
Synthetic Stopper Insertion Speed: When utilizing synthetic polymer stoppers on automated lines, ensure the corking machine's plunger speed and compression jaws are adjusted correctly. Synthetic materials have a different elasticity recovery rate than natural wood, and optimized machine timing prevents post-insertion "pop-back."
