Introduces 3M Scotchpak white release liners and white backing films
3M Scotchpak films allow the finished transdermal patch to be easy to see and easy to remember
3M Scotchpak white backing films allow the finished transdermal patch to be easy to see and easy to remember, increasing compliance with medication regimens. The film can be written on 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, the company says.
Global regulatory agencies have emphasised the need to make transdermal patches more visible and the new white backing enhances patch visibility on the patient, and the white liner makes it easier to peel prior to application on the skin.
The white liners are available in Premium release (1022W) and Ultra Premium Release (9755W), pictured, formulations
'We knew conspicuous patch backing and liner materials were needed in the market, based on customer demand and inquiries we received,' said Maurice Kuypers, Global Business Manager, Transdermal Components, 3M Drug Delivery Systems. 'Patients and caregivers alike will now have an easier time applying their patch products using the white liner or visually detecting the patch in the case of the white backing.'
The liners are available in Premium release (1022W) and Ultra Premium release (9755W) formulations, with 3M Scotchpak 9755W offering the lowest release within the 3M Scotchpak family of polyester release liners. According to 3M, 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 9733W can be used in the fabrication of both transdermal and dermal drug delivery systems.
