Unit of Measure Conversion Problem
Thank you so much. I figured that out after looking at my results and realized that I didn't have the permeability rate for one of the materials and that was only the WVTR, so I converted the units to what I had for the other film. Thanks so much for the input, though!- 310164977

Unit of Measure Conversion Problem
Hey guys, I don't know why I'm having such a hard time cancelling out units here, but here's my predicament. We send out a couple materials to have some MVTR (Moisture Vapor Transmission Rate) testing done to see the permeability of each film. The units we got back were in g/Pa*s*m^2. I have...- 310164977

Water Permeability of materials
The mold was ON the pouch, not inside. The pouches were from the polybags that they are shipped in and individually immersed them in sterile bags and added the extractant (Fluid D). The outside analysis firm says it seems unlikely that organisms could escape from within but all they really...- 310164977

Water Permeability of materials
Hey guys, Hope all is well! I'm running into an issue of mold growth in an aqueous-filled pouch that we have. The film material that houses this pouch is TPU. We also have a pouch that is houses by a PVC film, but this does not have the mold issue. Does anyone know why these two materials...- 310164977
