摘要:
A new adhesive seal or tape is provided which consists of a laminated product formed by the application of a strong adhesive to one side of a thin-leaf material that is extremely fragile and easily torn. To the other side of the thin-leaf material is laminated a stronger support sheet by means of an interlying adhesive layer. Adhesive tapes composed of the laminated material of this invention when used to seal a package prevent the secret pilferage or theft of the contents of the packages, since the tape is irreparably damaged when removed.
