ABSTRACT:
A tamper indicating seal is formed by a first laminate portion, including a layer of aluminum foil and a layer of a heat activated adhesive and a second laminate portion including a layer of heat resistant plastic film or foam and a layer of polyester film. The two laminate portions are secured together by an adhesive layer having two sections: a pattern section and a solid layer section. The solid layer section extends only to about 20% of the diameter of the seal and permanently secures the two laminate sections together. The pattern section covers the remaining portion and only lightly secures the two laminate sections together. The second laminate section can be easily removed from the pattern adhesive to form a pull tab to remove the seal from a container.
