The production of packaging requires materials resistant to
breakage and abrasion to protect the packaged product during
handling and transport while maintaining its flexibility to adapt
to eventual deformations of the product. Another important feature
is the opacity of the material because low opacity indicates
greater transparency, and for several products, it is important that
packaging is transparent for a good visual presentation. Other
times, protection against incident light is necessary, especially for
products that are sensitive to degradation reactions catalyzed by
light
