Bottle cap and rubber stopper

The bottle cap and stopper are the core components for sealing vials. The aluminum cap and stopper combination achieves both sealing and puncture functions, ensuring the sterility and safety of the medication.
Main Uses: Sealing vials, injection puncture.
Applicable Scenarios: Pharmaceuticals, biological agents, and injectable packaging.
I. Materials and Processes
Aluminum Cap Material: Aluminum alloy (customizable colors: gold/silver/blue/green/red, etc.), surface can be printed/anodized.
Stop Material: Medical-grade butyl rubber/halogenated butyl rubber (gray stopper/white stopper).
Process: Aluminum cap stamping, stopper molding and vulcanization; customizable colors and printing.
II. Specifications
Common Specifications: Matches 2ml/3ml/5ml/10ml/15ml/20ml/30ml vials.
Aluminum Cap Types: Three-piece aluminum cap set, aluminum-plastic combination cap.
Stop Types: Gray butyl rubber stopper, white coated rubber stopper.
Colors: Colored caps (gold/silver/blue/green/red, etc.).
III. Customization Instructions
Minimum Order Quantity: Standard models start with small batches; custom colors/printed models start with 5000-10000 units.
Delivery Time: Standard models 1-3 business days; custom models 10-15 business days.
Customization Process: Requirements communication → Specification confirmation → Sampling → Confirmation → Production → Shipment.
IV. Usage Precautions
Storage: Rubber stoppers must be stored in a sealed, light-proof container to prevent aging; aluminum caps should be protected from moisture and oxidation.
Usage: For medical applications, ensure the material meets pharmaceutical packaging standards (e.g., USP/EP); sealing requires a dedicated capping machine; puncture tests confirm the self-sealing property of the rubber stopper.
