Less extensible film — stiff overwrap from resin with a density of 0.935 g/cm3, or a high density, paper-like film — does not have the ability to stretch. The broad "smile" wrinkles appear if no attempt is made to increase the edge velocity. However, if the edge velocity is too great, edge wrinkles occur.

Optimizing output, improving efficiency, and reducing CO2 emissions while keeping investment costs to a minimum are common challenges that the modular vertical roller …
