Abstract

A product bag includes a bladder and an elongated filtration device. The bladder includes opposing first and second film layers defining a product chamber. The first and second film layers are sealed together along a perimeter seal extending along at least a portion of a perimeter of the bladder. The elongated filtration device includes a housing, a filtration membrane disposed in the housing, an inlet adapted for receiving a fluid to be filtered, and an outlet in fluid communication with the product chamber. A majority of the elongated filtration device is embedded between the first and second film layers of the perimeter seal of the bladder to provide for a compact form factor.
