Testing methods and equipment are provided for fast, non-destructive testing of the quality of seal and/or integrity of a package. According to certain embodiments, dynamic impact characterization is used to determine whether a loss of pressure due to a leak in the package occurs. The methods and equipment can be used in-line with product packaging processes. According to one embodiment, an initial pressure is applied to a package under test. A region of the package is impacted with a force sufficient to create a disturbance to the package while not destroying the package by using an impacting rod. Force sensors/transducers contact with the package and spaced a distance away from the impact region of the package detect a force signature from the impact. The existence of a leak is determined by evaluating the force signature.

Method and apparatus for quality of seal and package integrity testing

A method and apparatus is provided for measuring the oxygen transmission rate (OTR) of a material, such as a perforated film packaging material. The method and apparatus can use a fiber optic oxygen sensor that does not consume oxygen and does do not require any flowing gas during measurement of the OTR.
