A flexible panel in a sealable bag for disaster recovery has permeable inner layers and an impermeable outer layer affixed together so as to provide a plurality of cavities for receiving sorbent material. The cavities are arranged in a pattern across the flexible panel. A port is shown extending through all of the layers of the flexible panel. The port is used for introducing into and removing gas and/or liquid from the bag. The flexible panel may have one or more electronic components operable to monitor or control the chemical environment in the bag. The components may be affixed or printed on internal layers of the bag, such as: a conductor, a heater, a processor, a communications transmitter, a communications receiver and a GPS receiver. A remote module in electrical and/or wireless communication with the bag is operable to monitor and control the chemical environment in the bag

A formed body having a multilayered structure including inner and outer layers of a first ethylene terephthalate type polyester resin, and an oxygen-absorbing intermediate layer containing a non-polymer type organic oxygen absorber. The oxygen-absorbing intermediate layer, further, contains a second ethylene terephthalate type polyester resin that has relatively more copolymerizable units than the first ethylene terephthalate type polyester resin, the non-polymer type organic oxygen absorber being contained therein in an amount of not less than 5 parts by mass per 100 parts by mass of the second ethylene terephthalate type polyester resin.

Methods and systems for co-extruding multiple polymeric material flow streams into a mold cavity to produce a molded plastic article having an injection-formed aperture in gate region of the article are disclosed herein. A method includes providing a valve pin having a distal portion with a first diameter and a mid-portion with a second diameter smaller than the first diameter and providing a mold defining a cavity corresponding to a shape of a resulting molded plastic article. The mold has a recess aligned with a gate region of the mold, extending into the mold and configured to receive the distal portion of the valve pin when the distal portion of the valve pin extends beyond the gate region. The method includes advancing the distal portion of the valve pin into the recess until the mid-portion of the valve pin at least partially extends into the gate region, thereby establishing a flow path for a combined polymeric stream into the cavity at the gate region for forming a molded plastic article having at least one layer of a first polymeric material and at least one layer of a second polymeric material. The method also includes withdrawing the mid-portion of the valve pin from the gate region, thereby forming an injection-molded aperture in the resulting molded plastic article at the gate region.
