全文摘要：The seal comprises a piece of adhesive tape which is passed around the object and stuck to itself. The tape substrate comprises a crackable support so that pulling on either end of the tape will cause the support to become cracked and irreversibly damaged. Independent claims are also included for the following: (1) Multi layer adhesive tape for forming the seal, comprising a stretched thermoplastic film (10) with an optional release coating on the top side (12) and the following layers on the bottom side - a primer layer (14) which is well bonded to and covers part of the film, a separating layer (15) which is bonded to the primer layer better than to the film and which covers the primer layer, and an adhesive layer (16) which is bonded more strongly to the separating layer than to the film and which covers the release layer; (2) Multi layer adhesive tape for forming the seal, comprising a stretched thermoplastic film with an optional release coating on the top side and the following layers on the bottom side - a primer layer which is strongly anchored to the film and covers part of the latter, a first separating layer which is anchored to the primer layer more strongly than to the film and which c overs the primer layer, a second separating layer which is anchored to the first separating layer more strongly than to the film and which is bonds to the first separating layer less than strongly than the adhesive, and an adhesive layer which forms a stronger bond with
the second separating layer than the latter does with the first separating layer and which covers the s
