摘要

Multi-layered plastic foil (5) for the production of at least a two-piece interior layer, relockable packing tray, comprises an outer covering layer (6), which is optionally laminated on a carrier layer (4); an outer sealing layer (7) for the locking of the packing tray; an adhesive layer (8), which is arranged between the covering layer and the sealing layer; and a smell barrier layer (9) containing at least 40 wt.% of cycloolefin copolymer, which is arranged between the adhesive layer and the sealing layer. An independent claim is included for a cover or packing tray of an at least two-piece, relockable packing tray comprises the carrier layer, whose inner portion of the multi-layered plastic foil is laminated.
