Plastics comparison chart
The following chart compares characteristics for the most common types of resins used for plastic packaging. However, most data refers to tests done on sheets of resin (film) rather than rigid plastic bottles. For best results, Novio Packaging recommends that our customers always test their product in actual bottles to ensure compatibility.

*MVTR stands for Moisture Vapor Transmission Rate in g-mil/100in. 2/24hr. MVTR is a measure of the passage of gaseous H2O through a barrier. The lower the rate, the longer the package protects its contents from moisture and ensures the moisture content of the product remains the same.
**O2 and CO2 stand for Oxygen Transmission Rate (OTR) and Carbon Dioxide Transmission Rate (COTR) in cm3-mil/m2/24hr. OTR and COTR are measures of the amount of gas that passes through a substance over a given period. The lower the readings, the more resistant the plastic is to letting gasses through.
