摘要:
Devices, systems, and methods for preventing or reducing raised edges in wound films are disclosed herein. This improvement can be accomplished by employing a roll spacer that is narrower than the film and/or by entrapping a gas between the layers in the wound film. One or more embodiments of the present invention concern a multilayered wound film roll.
