A blank for forming a wrap-around pack for foodstuffs, comprising: a section of plastics film substrate, the film substrate section being generally rectangular with a front edge, a rear edge, and first and second outer edges, the outer edges (116, 118) being substantially parallel to the direction the blank is fed during assembly of the wrap-around pack; one or more sections of paperboard, adhesively attached to an outer surface of the film substrate, at least one section of the paperboard having at least one fold line, the fold line being substantially parallel to the outer edges (116, 118) of the film substrate; first and second side portions (146a, 146b) between the or each section of paperboard and the respective outer edge (116, 118), configured such that, when the pack is assembled, the first and second side portions (146a, 146b) can be attached to define a longitudinal seam; first and second end portions 148a, 148b, composed of the film substrate with no paperboard attached to it, such that, when the pack is assembled, each end portion 148a, 148b defines a free end of the wrap-around pack that can be heat sealed to define an end seam (204a, 204b); wherein the fold line defines at least two panels (144a, 144b, 144c) of the paperboard section, the panels (144a, 144b, 144c) arranged to be mutually angled when the pack is assembled; and wherein at least one panel (144a, 144b, 144c) of the paperboard section is configured to form at least part of a base of the pack when assembled, and wherein said longitudinal seam is configured to be substantially parallel to the or each fold line and located at the base when the pack is assembled. a section of plastics film substrate, the film substrate section being generally rectangular with a front edge, a rear edge, and first and second outer edges, the outer edges (116, 118) being substantially parallel to the direction the blank is fed during assembly of the wrap-around pack; one or more sections of paperboard, adhesively attached to an outer surface of the film substrate, at least one section of the paperboard having at least one fold line, the fold line being substantially parallel to the outer edges (116, 118) of the film substrate; first and second side portions (146a, 146b) between the or each section of paperboard and the respective outer edge (116, 118), configured such that, when the pack is assembled, the first and second side portions (146a, 146b) can be attached to define a longitudinal seam; first and second end portions 148a, 148b, composed of the film substrate with no paperboard attached to it, such that, when the pack is assembled, each end portion 148a, 148b defines a free end of the wrap-around pack that can be heat sealed to define an end seam (204a, 204b); wherein the fold line defines at least two panels (144a, 144b, 144c) of the paperboard section, the panels (144a, 144b, 144c) arranged to be mutually angled when the pack is assembled; and wherein at least one panel (144a, 144b, 144c) of the paperboard section is configured to form at least part of a base of the pack when assembled, and wherein said longitudinal seam is configured to be substantially parallel to the or each fold line and located at the base when the pack is assembled.
