The invention relates to the use of a multilayered, opaque, biaxially oriented polyolefin film of a vacuole-containing base layer and at least one inner cover layer comprising at least 30 - 95% by weight of a copolymer and/or terpolymer I having a seal initiation temperature I of 70 - 105 °C and 5 to 70% by weight of an incompatible polyethylene, each of the specifications in percent by weight being based on the weight of the inner cover layer and the inner cover layer having a seal initiation temperature II of 80 to 110 °C.

L'invention concerne l'utilisation, comme étiquette "In-Mould" lors d'un emboutissage, d'une feuille de polyoléfine multicouche opaque orientée biaxialement qui est issue d'une couche de base contenant des vacuoles et au moins d'une couche de recouvrement intérieure qui comporte au moins de 30 à 95 % en poids d'un copolymère et/ou d'un terpolymère I avec une température d'amorçage de scellage I de 70 à 105°C et de 5 à 70 % en poids d'un polyéthylène incompatible. Les indications en % en poids se réfèrent respectivement au poids de la couche de recouvrement intérieure et la couche de recouvrement intérieure présente une température d'amorçage de scellage I1 de 80 à 110°C.
