Abstract
A filmic label including a face material having a front side, a reverse side and an adhesive layer including pressure sensitive adhesive on the reverse side of the face material. The face material includes at least one surface layer on at least one side of at least one central layer. The at least one central layer includes cavities that have been initiated at initiation sites by stretching the face material in a longitudinal direction and in a cross direction. The cavities have been expanded in a thickness direction of the face material by allowing a gaseous substance to have an effect on the at least one central layer. Also a method for forming a plastic film for a filmic label.
Claims8
A filmic label, comprising:
- a face material having a front side, a reverse side and an adhesive layer comprising pressure sensitive adhesive on the reverse side of the face material, the face material comprising at least one surface layer on at least one side of at least one central layer, said at least one central layer comprising cavities which have been initiated at initiation sites by stretching the face material in a longitudinal direction and in a cross direction, wherein the cavities have been expanded in a thickness direction of the face material by allowing a gaseous substance to have an effect on said at least one central layer.
A method for forming a plastic film for a face material of a filmic label, the method comprising:
- providing the plastic film comprising at least one surface layer on at least one side of at least one central layer,
- initiating at initiation sites cavities in said at least one central layer by stretching the plastic film in a longitudinal direction and in a cross direction, and
- expanding the cavities in a thickness direction of the plastic film by allowing a gaseous substance to have an effect on said at least one central layer.
