USP Testing - MVTR and Packaging Performance
MVTR answers a simple question: how much moisture is getting through the container, and is that acceptable for this product?
Even small amounts of moisture can affect stability over time. Thatβs why MVTR matters most with moisture-sensitive products, especially solid and liquid oral dosage forms.
If that comprehensive testing isnβt conducted, it usually shows up later as a packaging issue you have to go back and fix, which can slow timelines and force rework.
