Patch: adhesive securement and covering

Optimized adhesion and patch recovering, breathability… the transdermal patch covering dressings designed by Adhex increase the adhesive area with no maceration for several days. They also do preserve the active ingredient while taking into account the importance of the regulatory aspect (DMF).

Securement and fixation of opioid, nitroglycerine, smoking cessation patches… Adhex matrix patch covering range has been developed by its R&D teams to improve adhesion performances by relying on the regulatory constraints and market standards (Drug Master File EU and US, ISO 10993). The adhesive portfolio proposed by Adhex is thus approved for skin contact and validated for pharmaceutical use. Transdermal matrix patches covering (systemic activity in relation to the blood system) or reservoirs offer an impressive number of additional skin contact points and adhesive surface improvements allowing the patch to last for one to several days as required (24 to 72 hours). These devices also meet breathability requirements to avoid the risk of maceration (> 800g/m²/24h). Thanks to a vertical integration, Adhex controls all the manufacturing steps, from coating to converting. Choice of adhesive materials: non-woven, TPU Meltblown, polyurethane films, printing of logos with inkjet technology allowing to specify the components of the patch, choice of release liners to facilitate die-cutting into patch, security films : siliconing, PE coating, choice of designs to simplify handling of the device: cuts, backsplits, IFU printing… Adhex offers fully customizable solutions.
