Comprehensive analysis of barrier materials

A recently published report provides volumetric and revenue forecasts for barrier materials through 2016.

By Pat Reynolds, VP/Editor

Produced by Allied Development Corp., the study examines the full range of commercially proven technologies from the perspectives of their functional ability to meet consumer needs, their worldwide market potential, economic profiles, and environmental impact. The 420-page study describes producer strategies for extending the life cycles of these established products, as well as the potential of several emerging technologies (e.g. ultra-high barrier metallized film) to improve or supplant them.

In-depth market, economic, and environmental analyses (depicted in more than 100 figures and tables) are presented for barrier materials that provide oxygen transmission rates from zero to 77.5 cc/meter squared/day and/or moisture vapor transmission rates from zero to 1.5 gm/meter squared/day. Shown here is a graphic illustration depicting the relative amounts of greenhouse gas (GHG) emissions that occur during the production of certain barrier films.

The study profiles 34 established and upcoming producers of barrier materials, serving the six major geographic markets for flexible packaging.

moisture vapor transmission rate

MVTR stands for "Moisture Vapor Transmission Rate", a measure of the passage of gaseous H2O through a barrier. It's also know as "WVTR", or "Water Vapor Transmission Rate". Moisture resistance is measured in a special chamber where it is divided vertically by the substrate/barrier material. A dry atmosphere is in one chamber, and a moist atmosphere is in the other. A 24-hour test is run to see how much moisture passes through the substrate/barrier from the "wet" chamber to the "dry" chamber. Standard test procedures (TAPPI T-464, ASTM E96) can specify any one of five combinations of temperature and humidity in the "wet" chamber. The toughest conditions are 100°F / 95%RH (Relative Humidity).
