Two-piece Heat Induction Seal Liner with Paper Layer

This liner is made up of aluminum foil layer and backup layer. It needs the induction seal machine. After induction machine provides a heat-seal laminate hermetically sealed to the lip of a container, the aluminum layer is sealed on the lip of the container and the secondary layer (cardboard of form) is left in the cap. The secondary liner as the reseal liner is left in the cap after heating process.

Factors Affecting Sealing

Contact width of sealing surface: the larger the contact width between sealing surface and gasket or packing, the longer the path of fluid leakage and the greater the flow resistance loss, which is beneficial to sealing. However, under the same compression force, the larger the contact width, the smaller the specific pressure. Therefore, the appropriate contact width should be found according to the material of the seal.

Fluid temperature: the temperature affects the viscosity of the liquid, thus affecting the sealing performance. With the increase of temperature, the viscosity of liquid decreases and the viscosity of gas increases. On the other hand, the change of temperature often leads to the deformation of the sealing components and easy to cause leakage.
