New Edge Compression Cartridge Allows Accurate Permeation Measurement of Paper Barriers
When improving the barrier properties of paper-based substrates, an unevenly applied coating can leave the surface uneven or rough. Barriers with rough surfaces are difficult to accurately test, as the high spots will seal against the cell while the valleys allow gases to flow, causing leaks and leading to erroneous test data.
The Edge Compression Cartridge is MOCON’s newest barrier-testing solution, enabling manufacturers to generate reliable, reproducible testing data for textured paper-based barriers. A compressive force mechanically eliminates micro-porosity, allowing analysis of these hard-to-test structures free of edge diffusion. With a smooth and consistent sample surface, test data is more reliable and repeatable.
Compared to masking, the Edge Compression Cartridge is easier to use, less wasteful, and more reliable; loading samples is quick, minimal grease is needed, and the cartridge can be reused indefinitely. Additionally, since the cartridge is stainless steel without an O-ring seal to the sample, the outgassing time is greatly reduced leading to faster tests.
