Resealable zipper-style lining

Abstract

The invention relates to a ring-drawn sealing liner comprising: a functional layer, a separating and strong adhesive layer, an electromagnetic induction heating layer, and a sealing layer. The functional layer of the ring-drawn sealing liner is made up of a principal cut and a tear line. The principal cut divides the ring-drawn sealing liner into an outer ring and an inner ring. The inner ring comprises the riser, the riser neck, and the hollow area. The riser neck is connected to the lower end of the riser. The hollow area is formed by cutting a secondary cut; this hollow area is located around the circumference of the riser and is connected to both sides of the riser neck.
