A portable flexible container integrity test device for conducting integrity testing of flexible containers is disclosed. The test device is particularly useful for testing aseptic flexible film bags in a manner that maintains the sterile nature of the container and removes crinkles by inflating the containers to remove crinkles and establish an inflation set point. The test device includes a programmable logic controller (PLC), a pressure transducer in electronic communication with the PLC, a power source configured to provide electrical power to the PLC, a blower in electronic communication with the PLC, a gas delivery pathway in selective fluid communication with the blower, and a human/machine interface in electronic communication with the PLC. The device is portable and configured to fluidly connect to a flexible container via the gas delivery pathway.
