As the global demand for advanced wound care and transdermal drug delivery grows, the quality of the base material—the plaster substrate—has become a critical factor in patient comfort and treatment efficacy. Changshu Yongdeli Spunlaced Non-woven Fabric Co., Ltd., a high-tech pioneer with nearly 20 years of expertise, is leading this transformation with its specialized medical spunlace nonwoven materials.
Specifically engineered for plaster manufacturers, Yongdeli’s latest spunlace solutions bridge the gap between high-performance drug delivery and superior skin compatibility.
Solving the “Breathability Gap” in Traditional Plasters
For decades, patients have struggled with traditional rubber-based plasters that cause skin irritation, moisture buildup, and painful removal. Leveraging its portfolio of 52 patents, Changshu Yongdeli has developed a fiber structure that addresses these clinical pain points directly.
By utilizing high-pressure water jet technology to entangle viscose and polyester fibers, Yongdeli creates a unique “funnel-shaped” microporous structure. This design allows for air permeability that is eight times higher than traditional substrates. This “narrow top and wide bottom” pore design effectively wicks away sweat and moisture while maintaining a protective barrier against dust and bacteria, ensuring a dry and sterile healing environment.
Advanced Compatibility with Global Adhesive Systems
One of the most significant challenges for plaster manufacturers is ensuring the substrate bonds perfectly with various medicated pastes and adhesives. Yongdeli’s spunlace nonwoven is engineered for universal compatibility, providing a stable foundation for:
Hot-melt adhesives and Rubber
Hydrogels and Silicone gels
Oil-based adhesives
This stability prevents “adhesive detachment” and ensures that the plaster stays firmly in place, even on high-movement areas like joints and acupoints. Clinical data and market verification show that plasters using Yongdeli’s substrate maintain a skin irritation rate of less than 3% even after a 72-hour application, making it ideal for pediatric use and those with sensitive skin.
Targeted Drug Loading and Controlled Release
Beyond physical comfort, Yongdeli’s material serves as an active component in the treatment process. The fiber pores are designed to evenly absorb and “lock” medicinal ingredients, preventing drug loss during storage.
This enables a layered targeted release mechanism:
Surface layer: Rapidly releases analgesic components for immediate relief.
Middle layer: Provides sustained release of active substances.
Bottom layer: Creates a “reservoir effect” on the skin to maintain stable efficacy for over 72 hours.
Sustainability Meets Customization
In line with the global shift toward “Green Medical” development, Yongdeli’s production process requires no chemical binders, retaining the natural properties of the fibers and ensuring the material is biodegradable.
Recognizing that aesthetics and patient psychology matter, Yongdeli offers a one-stop customization service. While skin-tone (flesh-colored) substrates remain the industry favorite for their discreet appearance, the company also provides custom colors and cartoon patterns for pediatric applications. With five professional production lines and an annual capacity of 5,000 tons, Yongdeli reliably serves major brands across North America, Europe, and Southeast Asia.
