Mono-web resealable package with tamper-evident tear strip
Abstract:
A reclosable package formed from a sheet having a layered structure formed on a first region of the outer surface proximate a top edge thereof, formed by a pressure-sensitive adhesive (PSA) and a sealant coating covering the PSA. The sheet is folded about transverse fold lines and side seals are formed along the two side edges of the sheet, and a flap portion of the sheet overlaps the layered structure. Permanent seals are formed between the sealant coating of the layered structure and the flap portion. The first permanent seal has a higher bond strength than that between the sealant coating and the PSA.
