Lid for heat-sealing container |
摘要 |
An improved lid for heat-sealing a container is proposed which comprises a substrate and an outer peel layer laminated to the substrate through two adhesive layers, one of which has a weaker adhesion strength than the other. The substrate has a base sheet and is formed with such a discontinuous cut outlining an opening that a tear starting from the end of one cut will be received by the front end of a cut next to the cut, and a partial opening will be formed in the substrate.
