Sealed liner, easy to peel.

Abstract

The invention proposes a peelable sealing liner (50) comprising a functional layer (100), a strong adhesive layer (200), an electromagnetic induction heating layer (300), a sealing layer (400), and a separating layer (210). The upper surface of the peelable sealing liner (50) comprises a lifting part (610), a lifting neck (620), and a hollow area (630) formed by cutting with a hollow cut line (720). The hollow area (630) is located at the periphery of the lifting part (610) and is connected to the two sides of the lifting neck (620). The functional layer (100) is formed with a tear line (710). One end of the tear line (710) is connected to the lifting part (610), and the other end of the tear line (710) and the outermost circle (OC) of the peelable sealing liner (50) are separated by a tear gap (715). Tear gap (715) is greater than 0 mm and less than or equal to 20 mm.
