Corks | Nomacorc

What makes Nomacorc closures a superior choice can be summed up in one word: consistency. Their patented co-extrusion manufacturing process creates engineered closures with a foamed core and an outer skin. These two elements work hand in hand to create predictable and consistent preservation results. The core is breathable and allows optimum oxygen transfer rates through the closure, while the outer skin provides a precise and consistent seal. In addition to its function, the skin has the appearance of natural cork and preserves the traditional ceremony of opening a bottle of wine, making Nomacorc appropriate for any and all occasions.

PATENTED CO-EXTRUSION PROCESS Nomacorc's patented co-extrusion process consists of two stages. First, raw materials are mixed, melted, and extruded to create a long, foamed cylinder, forming the closure’s core. Then a second extrusion process applies a flexible outer skin, which is thermally bonded to the inner cylinder. The shape is stabilized in cooling water before our high-speed cutting operation cuts the closures to the proper length.

BENEFITS/FEATURES

• Patented co-extrusion technology creates wine closures that provide consistent, predictable oxygen permeation, eliminating off-flavors due to oxidation, reduction, or cork taint
• Uniform, small cell structure of foamed core, combined with elastic skin, provides more precise preservation performance than that of natural, technical, agglomerated, or screw-cap closures
• State-of-the-art manufacturing technology produces closures that are identical from batch to batch, resulting in trouble-free bottling with traditional corking equipment
• Patented flexible skin ensures a long-term, tight neck seal, eliminating leakage, breakage, and crumbling
• Manufactured with food-industry-approved, inert materials
• Cosmetically optimized color and texture closely replicate look and feel of natural cork and maintain the traditional bottle-opening ceremony
