Zusammenfassung:Cover tapes for securing electronic parts in a carrier tape are provided. The cover tape includes opposing edges extending along a longitudinal direction of the cover tape orthogonal to a transverse direction, and first and second layers. The first layer is stretch-oriented along the longitudinal direction at a first stretch ratio, and the first and second layers are stretch-oriented along the transverse direction at a second stretch ratio greater than the first stretch ratio. The cover tape further includes a first major surface extending along the longitudinal direction and between the opposing edges, the first major surface including a plurality of linear depressions extending along the longitudinal direction. The cover tape is hand-tearable along each linear depression. Also, assemblies and methods for making cover tapes are provided.
