Thickness units
Mil - 0.001 inch, ex) 3 mils = 0.003 x 25.4mm = 0.0762mm = 76.2 microns
Micron - 1/1,000,000m (1/1,000mm = 0.001mm), ex.) 100 microns= 100/25.4 = 3.93mils
MM - 0.15mm = 150 microns
MVTR
The Mdsture Vapor Transmission Rate (MVTR) is the rate that water vapor passes through a specific area of barrier material. MVTR is measured in grams of water vapor per 100 square inches of barrier per 24 hours (g/100 in.2/24 h).
EIA 583 Packaging Material Standards for Moisture-Sensitive Items defines a Class 1 barrier having an MVTR of <0.02 g/100 in.2/24 h.A Class 2 barrier is set at <0.08 g/100 in.2/24 h.
