A resealable package for a product, comprising: a sheet having an outer surface and an opposite, product-facing inner surface, the sheet having a top edge and an opposite bottom edge each extending in a transverse direction, and two opposing side edges each extending in a perpendicular longitudinal direction, between the top and bottom edges (21, 22); a layered structure formed on a discrete first region of the outer surface proximate the top edge thereof and extending substantially from one of the side edges to the other of the side edges, the layered structure comprising a pressure-sensitive adhesive, PSA disposed on the first region of the sheet, and a non-tacky sealant coating disposed over and covering the PSA such that the PSA is not exposed as long as the sealant coating is in place; the sheet having a fold that extends in the transverse direction, so as to envelop the product, with the inner surface of the sheet facing the product, side seals being formed along the two opposing side edges of the sheet, sealant material disposed on the inner surface of the sheet at least along the two opposite side edges for forming the side seals, and along a first portion of the inner surface of the flap portion of the sheet, and a flap portion of the sheet adjacent the bottom edge thereof overlapping the layered structure and the sealant material; and a first permanent seal between the sealant coating of the layered structure and the sealant material on the first portion of the inner surface of the flap portion of the sheet; wherein the first permanent seal has a bond strength exceeding that existing between the sealant coating and the PSA, such that peeling back the flap portion causes the sealant coating to be lifted from the PSA and thereby exposes the PSA, which can then be used for resealing the flap portion to reclose the package; characterised in that, the package further comprising a sealant material disposed on a second region of the outer surface of the sheet adjacent the layered structure, and a second permanent seal between the sealant material on the second region and a second portion of the inner surface of the flap portion, whereby peeling back the flap portion requires first severing the flap portion at a location between the first and second permanent seals (38, 39). a sheet having an outer surface and an opposite, product-facing inner surface, the sheet having a top edge and an opposite bottom edge each extending in a transverse direction, and two opposing side edges each extending in a perpendicular longitudinal direction, between the top and bottom edges (21, 22); a layered structure formed on a discrete first region of the outer surface proximate the top edge thereof and extending substantially from one of the side edges to the other of the side edges, the layered structure comprising a pressure-sensitive adhesive, PSA disposed on the first region of the sheet, and a non-tacky sealant coating disposed over and covering the PSA such that the PSA is not exposed as long as the sealant coating is in place; the sheet having a fold that extends in the transverse direction, so as to envelop the product, with the inner surface of the sheet facing the product, side seals being formed along the two opposing side edges of the sheet, sealant material disposed on the inner surface of the sheet at least along the two opposite side edges for forming the side seals, and along a first portion of the inner surface of the flap portion of the sheet, and a flap portion of the sheet adjacent the bottom edge thereof overlapping the layered structure and the sealant material; and a first permanent seal between the sealant coating of the layered structure and the sealant material on the first portion of the inner surface of the flap portion of the sheet; wherein the first permanent seal has a bond strength exceeding that existing between the sealant coating and the PSA, such that peeling back the flap portion causes the sealant coating to be lifted from the PSA and thereby exposes the PSA, which can then be used for resealing the flap portion to reclose the package; characterised in that, the package further comprising a sealant material disposed on a second region of the outer surface of the sheet adjacent the layered structure, and a second permanent seal between the sealant material on the second region and a second portion of the inner surface of the flap portion, whereby peeling back the flap portion requires first severing the flap portion at a location between the first and second permanent seals (38, 39).
