Manufactured from high-quality aluminum, the cap offers excellent corrosion resistance, lightweight performance, and an elegant metallic appearance that enhances the overall presentation of bottled wines.

ROPP Application Requirements: This product is an ROPP (Roll-On Pilfer-Proof) aluminum closure that requires a dedicated ROPP capping machine for roll-on forming. Please verify that your filling line is equipped with ROPP capping equipment or confirm equipment compatibility with your contract manufacturer before purchasing.
Neck Finish Compatibility: The precision of the fit between the aluminum closure and the glass bottle neck directly affects sealing performance. Ensure the bottle neck finish specifications match the selected closure (e.g., 30mm, 28mm, 31.5mm). We recommend submitting samples for compatibility testing prior to mass production.
Liner Selection for Oxygen Management: Standard products come with a PE-laminated liner. For wines intended for aging, we recommend multi-layer composite liners such as Saranex™ or Sarantin™, which allow for precise oxygen transmission rate control and eliminate the risk of cork taint (TCA odor).
Hot Fill vs. Cold Fill: This product is suitable for cold-filled products (still wines, spirits, etc.). For hot-fill applications, please consult our sales team regarding the need for high-temperature resistant liners (e.g., PVC full-seal liners capable of withstanding up to 121°C).
Minimum Order Quantity (MOQ): Custom colors, printed logos, and special liners typically require higher MOQs; please confirm specific MOQ and lead times with our sales team.
Compliance: Ensure the product complies with food-contact material regulations in your target market. Our aluminum materials and liners meet both FDA (USA) and EU (European Union) standards.
