Metal Closure Customization


As a tireless innovator, Tecnocap develops special designs to enhance the package for those customers who believe in metal closures as a marketing tool.

We are focused on providing closures with excellent quality and technical performance and supporting customers who wish to heighten their brand reputation.

Tecnocap designs customized closures in a wide range of colors, shapes, sizes and materials to meet your highest expectations with the ambition to make your package highly noticeable on the shelf.


From a single color to a multi-color photographic image, customized closures can be an integral part of a package, which separates a product from its less attractive competition. All colors and prints are applied in Tecnocap’s lithography facilities, never subcontracted.

Heat Seal Liners offer tamper evident protection. The Heat Seal liner is part of a double liner system.
When the closure is applied, the adhesive is melted through heat induction, and the liner adheres to the container, providing a tamper evident seal.
The opposite side of the liner is typically printed with “Sealed For Your Protection” or “Safety Seal™.”
The Heat Seal liner can be provided with a custom print.
When the customer removes the Metal Closure, the Heat Seal liner remains on the jar neck ring whilest the second liner remains in the cap to seal the container for reapplication.


Choosing the liner type and style is one of the most important factors of a Metal Closure selection.
The liner is a round piece of material that sits between the cap and the jar/container.
Its primary function is to offer proper sealing of the product and often times it determines the Metal Closure fit and function viability.
Since the liner facing is in direct contact with the product, the compatibility is critical.  Liners will help ensure shelf life performance and stop leakage of the product.
Certain products require specialized liners.  Different liner materials are available for moisture barrier, chemical resistance, consumer safety, or preventing leakage.
Tecnocap’s Liner Division has developed further specialized liners such as Pressure Sensitive, PVC-free, Plasticiser-Free, ESBO-Free alongside the Heat Seal.
