Pinch-pull type closure liner

A pinch-pull type closure liner, comprising:

• a functional layer, comprising a surface film and a bonding film sequentially from top to bottom;
• a sealing layer, located below the functional layer;
• a release layer and a strong adhesion layer, the release layer and the strong adhesion layer are located between the surface film and the sealing layer;
• and
• an electromagnetic induction heating layer, located between the surface film and the sealing layer;
• wherein the functional layer of the pinch-pull type closure liner is provided with a first tearing area, a hollow area, a first tearing line, a second tearing line and a secondary cutting line;
• the first tearing area comprising:
• a lifting part;
• a lifting neck, connected with the bottom end of the lifting part and having a first connection point and a second connection point;
• the first tearing line, connected with the first connection point at one end;
• and
• the second tearing line, connected with the second connection point at one end;
• and
• the hollow area is formed by cutting the secondary cutting line, a thickness thereof is less than a thickness of the pinch-pull type closure liner, and the hollow area is located at a periphery of the lifting part and is connected with two sides of the lifting neck;
• the release layer and the strong adhesion layer are located on a lower surface of the bonding film corresponding to the lifting part or an upper surface or a lower surface of the electromagnetic induction heating layer.
