The sealing of cosmetics needs to consider the user experience, such as whether it is convenient to open, whether the appearance, printing and texture can attract consumers; as well as highlighting the brand image or marketing effect.

A one-piece induction sealing liner can relatively easily achieve these effects. Sometimes a one-piece or half-pull-tab induction sealing liner can be used in combination with a foam liner made by a special production process, which can further enhance the user experience.
