The converter’s answer typically includes the phrase “it depends.”

So what does it depend on?

There are many factors that determine what the number is and why it can vary by individual project.

  • Chemical resistance

  • Puncture resistance

  • Tear resistance

  • Rigidity

  • Glossy or matte appearance

  • Opacity or translucency

  • Heat sealability
