Aluminum-Plastic Cap with Glass Ball Insert

The Aluminum-Plastic Cap with Glass Ball Insert is made of an aluminum outer shell combined with a plastic liner (such as PE, PP, or PET), offering both the strength of metal and the lightweight characteristics of plastic. The glass ball is typically embedded in the internal structure to prevent liquid re-filling and enhance anti-counterfeiting features.

• Aluminum Outer Shell: Provides corrosion resistance, tamper-proof ability, and supports surface treatments (such as printing, embossing, UV coating).
• Plastic Liner: Ensures sealing, prevents leakage, and adapts to different temperature environments.

Glass Ball Function

The glass ball acts as a backflow prevention device, automatically locking after the cap is sealed, preventing liquid from being reinserted. It is commonly used in high-end alcoholic beverage packaging such as whiskey and vodka.
