Understanding Film Properties

In order to understand flexographic film properties, Poly Print Inc. provides answers to many of the questions that are often asked about film property testing, including:

  1. How is this property measured?
  2. What is the ASTM test method number?
  3. What affects the value of this property?

We also discuss when and why the property is important. Sometimes we compare typical OPP property values with the values for other films. In short, we have tried to design a complete and organized resource about the properties used to characterize flexible packaging films.

The discussion about each property follows the same format.
