Why Barrier Performance Matters
A film's barrier is one of the most important layers in flexible packaging that can determine the preservation, shelf life, and production cost of your product. Learn what material properties perform best for your product's packaging!
HOW IT WORKS
Barrier performance is determined by three main factors: material type, number of layers, and the layer thickness. It's all about finding the right balance!
HOW IT'S MEASURED
Barrier Performance can be measured in two ways, WVTR and OTR. The lower the WVTR and OTR of the film, the higher the barrier performance it has (film is less permeable).

Water Vapor Transmission Rate (WVTR)
Measured in cc/m²/day
Oxygen Transmission Rate (OTR)
Measured in g/m²/day
