uniformly tight with no evidence of bagginess or wrinkles nor does it relax upon cooling as the outer layer 11 of the tape backing is peeled from the bottle opening it delaminates from inner layer 12 because of the adhesive versus cohesive strengths within the product thus evidence of tampering is highly apparent furthermore delamination of the outer layer 11 will generally cause a partial stretching out of the thin inner layer 12 further increasing the evidence of tampering to provide additional visual tamper indication printed or colored layers can be utilized normally the somewhat fragile inner layer 12 would be printed utilizing distinctive designs which would increase the visibility of tampering furthermore printing onto colored layers on either or both sides provides the tape with a more complicated and more aesthetic tamper indicating packaging for example printing in white on a blue outer layer 11 together with the printing of a message in for example blue on the preferably transparent inner layer 12 of the tape backing provides aesthetic appearance and evidence of tampering by virtue of the hidden message contained on the thin inner layer 12 as the blue outer layer 11 is peeled from the bottle the colored message or logo would be clearly visible through the transparent inner layer 11 adding yet another degree of tamper resistance to the product in the unitizing embodiment individual containers such as small cereal boxes can be rendered a unitary structure as fig3 illustrates the tape 15 can be applied over a number of individual containers 21 as the tough outer backing layer.
