A packaged product includes an overwrap material wrapped around the product and overlapped to form a seam bonded to prevent ingress of moisture and a tear tape to tear the overwrap material. The tear tape has a first pressure sensitive layer for bonding to the overwrap and a second layer opposite the first having characteristics such that it acts as a release coat toinhibit bonding of the tear tape to itself and such that it acts to bond the substrate to the overwrap material. The second layer converts by heat from the release coat condition to the bonding condition by being absorbed into the first sub-layer or by including a hard rough surface arranged to inhibit bondingto the first layer which is melted.
Produit emballé comportant une enveloppe de suremballage à recouvrement et dont l'extrémité libre est scellée par collage au moyen d'un ruban adhésif avec bandelette d'ouverture pour prévenir toute pénétration d'humidité. Le ruban adhésif à bandelette d'ouverture comporte une première face enduite d'une couche autoadhésive pour collage au matériau de suremballage, et une deuxième face possédant des propriétés antiadhérentes empêchant le ruban de coller à lui-même. L'application de chaleur permet à une sous-couche d'absorber les propriétés antiadhérentes de la deuxième face du ruban et d'en restaurer les propriétés autoadhésives.
