Product Description
Alu-Plastic T-Top Stopper 19.5mm with Wood Synthetic Cork for Spirits
Product Overview

Our T-shaped bar-top stopper is specifically designed for spirits and other beverage bottles that utilize cork-style closures. This closure solution combines a sturdy top with a compressible sealing shank, ensuring a secure seal while offering optimal brand presentation.

Head Options
  • Aluminum Head: Durable, lightweight, and recyclable. Ideal for ultra-premium spirits positioning.
  • Plastic Head (PP/ABS): Cost-effective with highly flexible color options, suitable for large-scale production.
Shank Options
  • Natural Cork: Harvested from cork oak bark, offering heritage appeal, sustainable branding, and controlled oxygen ingress.
  • Synthetic Cork (TPE): Food-grade elastomer providing excellent ethanol resistance, consistent dimensional stability, and zero risk of TCA contamination ("cork taint").

We offer complete customization including head color (Pantone matching), logo engraving (laser, embossing, debossing), and surface finishing (glossy, matte, anodized).

Stopper applications in various spirit bottles and packaging scenarios
Important Precautions
Strict Inner Neck Tolerance Verification (Bore Matching):
Unlike screw caps, T-top stoppers rely on an interference fit (press-fit). The shank diameter must be precisely matched to the bottle's inner neck diameter. We strongly recommend sending us your bottle drawing or physical glass samples to test the fit before ordering.
Moisture Control for Wood Cork Storage:
Bulk stock of natural cork stoppers must be stored in a dry, well-ventilated warehouse with relative humidity kept between 50% and 70% and temperatures below 25°C (77°F). Excess humidity can cause mold on wood tops, while extreme dryness will cause the cork to shrink and lose its sealing memory.
Capping Tool Adjustment:
For automated bottling lines, ensure the pneumatic plunger or capping jaw is fitted with a soft silicone or non-marring rubber pad. Excessive direct metal pressure on the top cap can scratch the anodized aluminum coating or crack plastic caps.
