An improved innerseal for sealing containers includes a body portion (22) having an upper surface and structure (24) connected to the upper surface for grasping by a user, whereby the body portion may be removed from a container quickly and efficiently. The body portion includes structure for preventing passage of fluid therethrough, and structure for bonding the body portion against the upper rim of the container with a first bonding force. The bonding structure has a first bonding portion for sealing against the container rim and a second bonding which is adhered to the first bonding with a second bonding force which is greater than the first bonding force. Consequently, a first part of the first bonding portion will delaminate from the second bonding portion over the container rim and re- main adhered to the rim, while a second part of the first bonding portion will remain adhered to the sec- ond bonding portion, thereby exposing the opening in the container when the grasping structure is pulled. A method for manufacturing containers so sealed is also disclosed.
