Polyurethane Empty Medicated Patch

Our Medical Polyurethane Hollow Plaster is a high-tech carrier designed for the customized delivery of powdered medicines, ointments, and liquid formulations. Manufactured from premium medical-grade Polyurethane (PU) film, this innovative patch serves as a "blank canvas" for compounding pharmacies, TCM clinics, and hospitals requiring personalized treatment solutions.

The product is constructed using a solvent-free, breathable PU membrane that offers exceptional biocompatibility and transparency. The production process involves precision die-cutting and high-pressure lamination to ensure the absorbent core pad (made of viscose or non-woven fabric) is securely fixed within the plaster cavity . Unlike traditional cloth tapes, our PU material is hypoallergenic, latex-free, and features a microporous structure that allows moisture vapor and air to pass through (MVTR > 800 g/m²/24hr), preventing skin maceration while maintaining a waterproof barrier against external contaminants. The adhesive layer utilizes a medical-grade acrylic gel, providing secure skin adhesion without leaving painful residue upon removal . We offer customizable sizes and shapes (round, square, or anatomical contours) to accommodate varying drug volumes and application sites .

As a specialized OEM/ODM manufacturer in the medical device sector, we pride ourselves on vertical integration and stringent quality control. Our facility operates in compliance with ISO 13485:2016 standards, ensuring that every batch is produced under strict environmental monitoring. We utilize automated coating and slitting lines to guarantee uniform thickness and consistent peel adhesion (typically 1.0–2.0 N/cm). With over a decade of industry experience, we offer rapid prototyping and private labeling services to help healthcare brands launch their products efficiently. Our supply chain utilizes only virgin raw materials sourced from FDA-registered suppliers, ensuring stability and lot-to-lot consistency.
