摘要： The present disclosure is directed to compositions and film structures suitable for heat seal production. The heat scalable flexible film structure includes: a layer (A) comprising a blend comprising from 35 to 80 percent by weight of the layer (A) of a propylene based plastomer or elastomer ("PBPE") and from 20 to 65 percent by weight of the layer (A) of a low density polyethylene having a density in the range of from 0.915 g/cm 3 to 0.935 g/cm 3 , wherein the blend has a melt index (as determined according to ASTM D-1238 (at 190°C/2.16 Kg) a layer (B), adjacent to layer (A), comprising a polyolefin-based polymer, wherein the polymer or polymer blend which makes up layer (B) flows more easily than the blend of layer (A) under conditions intended for making a hard seal with the film structure; and an outermost layer (C) comprising a material having a melting point greater than 140°C; wherein the ratio of the thickness of layer (B) to the thickness of layer (A) is 3:1 or greater. The heat scalable flexible film structure is used to make a flexible container having one or more heat seals. The heat seal can be a frangible heat seal, a hard heat seal, or a combination of frangible heat seals and hard heat seals depending on the sealing conditions.

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： 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.
