The company develop flexible barrier materials utilizing a unique corona beam technology, for pharmaceutical, medical, and food packaging.
The detection of viral and sub-viral sized (as small as 0.5 nanometres) apertures, voids, holes, blisters, contaminants, stress fractures, overlapped material, formulation defects and other anomalies are critical to the product’s protective or performance function.
This technology relates to an electronic measuring method and apparatus which utilizes electron beams in an open atmosphere (i.e. Corona Beams) and electronic instrumentation to measure the constructive and destructive harmonics of the frequency loaded electronic corona discharge from the holes or anomalies in order to qualify, quantify and map their integrity or performance criteria.
The porosity, permeability or integrity of a non-conductive medical and consumer flexible barrier packaging material is determined utilizing a novel electron beam technology and electronic instrumentation in an open atmosphere. The electron beam developed in an open atmosphere maintains its prescribed frequency through the use of a nitrogen cover gas, ionizing the gas to create a corona beam. The corona beam discharge, maintained at a high positive voltage, forms from the holes or anomalies in the flexible non-conductive barrier material.
The anomaly is detected and analyzed in order to determine the presence of viral and sub-viral sized voids or holes, as well as other anomalies such as blisters and bubbles. This process can be performed by the flexible barrier film manufacturer to certify a quality level. It can be performed by the material fabricator to ensure quality standards. It can also be performed by the product manufacturer that uses the packaging material to wrap their products and confirm the integrity of the sealed package by measuring the atmosphere inside the finished package.
