Backings

Formulation design and patient preference can have a significant impact on your choice of backing. 3M offers a wide variety of backing materials to help ensure suitability and success.

3M™ CoTran™ Backings
Translucent flexible backings that address skin health by increasing moisture near the skin to maintain skin hydration while allowing the skin to breathe.

3M™ CoTran™ Nonwoven Backings
With multi-directional stretch and mechanical strength in all directions, these backings are ideal for large transdermal patches.

3M™ Scotchpak™ Backings
Polyester-based film laminates created without an adhesive tie layer to minimize the potential for drug and/or excipient interactions.
