Abstract: Methods of making containers are provided, including providing a material sheet having at least two barrier layers and at least two polymer layers, forming the material sheet into a tube, sealing the tube at a seal area, and blow molding the tube to form a container in which the at least two barrier layers form a substantially continuous barrier at the seal area.

Abstract: Blow molded containers and methods for making the same are provided. A blow molded container has a container wall including a thermoplastic polymer material having a rheology melt strength (Rms) of at least 30 Pa·s2. A method of making a container includes providing a material sheet including at least one thermoplastic polymer layer having a rheology melt strength (Rms) of at least 30 Pa·s2, forming the material sheet into a tube, sealing the tube at a seal area, and blow molding the tube to form a container.

Abstract: This invention relates to films having selective permeability and/or permeation rates for different gases, liquids, particulate matter, and combinations thereof. The films may be employed as packaging films or separation membranes. The films may be comprised of at least one layer including one or more high permeability polymers blended with one or more low permeability polymers. Blending of different amounts and combinations of low and high permeability polymers may provide a method by which individual permeation and permeation rates can be increased or decreased, and made selective for one or more gasses, liquids, particulate matter or combinations thereof. Methods for making such films are also disclosed.
