3M Drug Delivery Systems introduces 3M™ Scotchpak™ white release liners and white backing film. These transdermal components provide high visibility and improve ease of use for patients and caregivers.
3M Scotchpak white backing films make the finished transdermal patch easy to see and easy to remember, increasing compliance with medication regimens. The film can be written on by the patient or a caregiver to note both the time of dosing and dose given. It can also be printed on both sides with graphics, logos, or instructions.
The release liners are coated with a proprietary 3M fluoropolymer that provides premium release from skin contact adhesives, including silicone, acrylates, polyisobutylene (PIB) and rubber-based pressure-sensitive adhesives. The liners also provide excellent chemical stability for a long shelf life.
Recently global regulatory agencies have emphasized the need to make transdermal patches more visible. The new white color backing enhances patch visibility on the patient, and the white liner makes it easier to peel prior to application on the skin.
The liners are available in Premium release (1022W) and Ultra Premium release (9755W) formulations, with 3M Scotchpak 9755W offering the lowest release in the 3M Scotchpak family of polyester release liners. This liner performs well with soft, pressure-sensitive adhesives that have lower internal cohesive strength. The backing is available as 3M Scotchpak white backing film (9733W), a laminate of polyester and ethyl vinyl acetate that offers occlusivity and conformability.
Available in roll form, 3M Scotchpak 9755W/1022W and 3M Scotchpak 9733W can be used in the fabrication of both transdermal and dermal drug delivery systems.
