ABSTRACT:
The invention provides a package for packaging of products which provides evidence of tampering with or adulteration of the product by providing a readily visible indication that any such tampering or adulteration has occurred. The invention in one form provides an inner container which is in turn at least partially covered with a tamper evident packaging material. The packaging material is a tamper evident composite material comprising a photopolymerizable composition layer which is cured and it becomes extremely brittle such that any physical penetration of this packaging material will cause the brittle layer to fracture or shatter. Such shattering will provide a clear indication that penetration of the packaging material has occurred. Also there may be provided an asociated dye which will exhibit a color change when the brittle layer is fractured or shattered. The tamper evident composite material of the present invention is also useful in the form of a non-transferable label or sticker which cannot be removed of re-use in that the brittle laeyr thereof fractures or shatters when the label or sticker is removed or tampered with.
