Abstract

Die vorliegende Erfindung betrifft eine siegelbare, thermoformbare, wärmeschrumpffähige Mehrschichtfolie mit einem symmetrischen Aufbau um eine zweilagige Innenschicht und mit einer Wärmeschrumpffähigkeit in Längs- und in Querrichtung von jeweils wenigstens 20% bei 93 °C, wobei die Wärmeschrumpffähigkeit durch eine Thermoformung im wesentlichen nicht beeinflusst wird, sowie Verfahren, gemäß denen die erfindungsgemäße Mehrschichtfolie vorteilhaft zu wärmegeschrumpften Verpackungen verarbeitet werden kann, insbesondere unter Einsatz speziell ausgerüsteter Verpackungsmaschinen.
