摘要： Embodiments of a flexible pouch (1) comprise a pouch body (10), a collapsible perforated folded panel (50), an opening seal (60) disposed between the collapsible perforated folded panel and the second ends (18, 19) of the front wall (12) and the rear wall (14), wherein the opening seal adheres the second end of the front wall to the second end of the rear wall which thereby conceals the collapsible perforated folded panel. The release or removal of the opening seal is operable to expose the collapsible perforated folded panel and application of a pull force is operable to outwardly expand the collapsible perforated folded panel to allow draining of liquid or dispensing of dry powder or flakes from the pouch chamber.

摘要： The present invention provides methods of preparing peelable seal layers, methods of preparing multilayer films, peelable seal layers made therefrom, and multilayer films made therefrom. In one aspect, a method of preparing a peelable seal layer comprises (a) providing a first blend comprising (i) from 5 to 98 percent by weight of a reactor grade propylene based plastomer or elastomer having a molecular weight distribution of less than 3.5 and a density of less than 0.89 g/cc and (ii) from 2 to 95 percent by weight of a second polymer selected from the group consisting of polyethylene, polybutylene, and styrenic polymer and mixtures thereof; (b) providing at least one linear low density polyethylene; (c) blending the first blend with the at least one linear low density polyethylene to obtain a second blend; and (d) extruding the second blend to form a peelable seal layer, wherein the peelable seal layer has a heat seal initiation temperature less than 120° C when sealed at a bar pressure of 40 psi with a dwell time of 0.5 seconds.

摘要： Embodiments of containers are provided, the containers(1) having a container body (10) having a sealing lip (12), wherein the sealing lip comprising an opening end (16) and a seal end (14) spaced from the opening end. The container also comprises a bottom perforated film (20) adhered to the sealing lip at a first adhesion strength (S1), and a top film (30) adhered to the bottom perforated film at a second adhesion strength (S2) at locations not vertically aligned with the seal end, and wherein the top film adheres to the bottom perforated film at a third adhesion strength (S3) at the seal end. The third adhesion strength is greater than the first adhesion strength which is greater than the second adhesion strength, such that the top film is peelable relative to the bottom perforated film at the opening end, and the top film is peelable with the bottom perforated film relative to the container body at the seal end.
