Choosing the right Liner. The overlooked element between your product and our Metal Closure.

Choosing the right Liner. The overlooked element between your product and our Metal Closure.

Choosing the liner type and style is one of the most important factors of a Metal Closure selection.
Pressure Sensitive Liners offer tamper evident protection and peace of mind.

The liner is a round piece of material that sits between the cap and the jar/container.
It’s 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 specialised liners, different liner materials are available for moisture barrier, chemical resistance, consumer safety, or preventing leakage.

Tecnocap’s Liner Division have developed further specialised liners such as Heat Induction, PVC-free, Plasticiser-Free, ESBO-Free alongside the Pressure Sensitive.

The Pressure Sensitive liner is part of a double liner system.
When the closure is applied, the pressure sensitive liner uses a light adhesive to adhere to the container.
The opposite side of the liner is typically printed with “Sealed For Your Protection” or “Safety Seal™.”
The pressure sensitive liner can be provided with a custom print.
When the customer removes the Metal Closure, the pressure sensitive liner remains on the jar neck ring whilst  the second liner remains in the cap to seal the container for reapplication.
