Closure seal for a container |
摘要 |
A seal for a container opening includes a backing layer and a seal layer for connecting to and covering an opening of the container. A pull-tab forming layer is sandwiched between the backing layer and the seal layer. The pull-tab forming layer has a heat sealable surface joined to the backing layer. An opposite heat resistant surface is joined to the seal layer. A hinge is disposed near the center of the seal that joins the backing layer and the sealed layer wherein the backing layer and at least a portion of the pull-tab forming layer define a pair of pull-tabs extending from the hinge. A method of forming the seal including the pull-tab forming layer and a material blank for forming a plurality of the seals are also described.
