Unishell Lids
The Unishell Cap is a premium tinplate internal thread closure with a unique and innovative structure, distinctly different from traditional external thread screw caps.
Featuring concealed internal threads, it boasts a smooth, seamless exterior surface with no exposed thread lines, creating a minimalist, elegant and high-end aesthetic that greatly enhances packaging appearance and product grade.
This special internal thread design effectively prevents thread wear, dust accumulation, dirt trapping and corrosion, keeping the packaging clean, intact and stylish even during long-term storage and repeated use.
This high-quality tinplate closure is non-toxic, sturdy, durable and structurally stable, combining excellent practicality with premium visual appeal. Unishell caps are widely applied to food, beverage, cosmetic and daily consumer goods packaging.
