<p>The present invention relates to a sealable, thermoformable, heat-shrinkable multi-layer film having a symmetrical construction around a two-ply inner layer, and having a heat-shrinkability in machine direction and in cross direction of in each case at least 20% at 93°C, the heat-shrinkability being substantially unaffected by thermoforming, and also to methods whereby the multi-layer film of the invention can be processed advantageously to heat-shrunk packaging, more particularly using specially equipped packaging machines.</p> |
