YDL pitches medical spunlaced nonwovens for plasters and wound dressings

Changshu Yongdeli Spunlaced Nonwoven Co., Ltd. is promoting a medical spunlaced substrate designed for plasters and wound dressings, claiming better breathability, skin compatibility and adhesive flexibility. The company says the material targets global patch makers that need one substrate to work across multiple adhesive systems and production lines.

Why it matters: - Patch substrates help determine comfort, skin safety, adhesion stability and drug release performance in plasters and wound dressings. - YDL is targeting manufacturers that struggle with skin irritation, weak durability and limited adhesive compatibility. - The company is also positioning the material for global medical patch brands that want fewer substrate changes across product lines.

What happened: - Changshu Yongdeli Spunlaced Nonwoven Co., Ltd. introduced YDL Medical Spunlaced Nonwovens for plasters and wound dressings. - The company is based in Jiangsu, China, and describes itself as a Jiangsu Province Specialized & Sophisticated Enterprise. - YDL says the product is designed for topical patches used in chronic pain management, wound care and medical aesthetic repair. - The company says it has nearly 20 years of experience in spunlaced nonwovens, a 100,000-class clean workshop, more than 20 patents and internationally advanced production lines.

The details: - YDL says the substrate uses a high-pressure spunlace chemical-free bonding process with medical-grade viscose, bamboo fiber and polyester. - The material is said to form a 3D porous structure with 10-50μm uniform micropores. - YDL says the breathability rate reaches 1200g/m²·24h, about twice that of ordinary nonwovens. - The company says the product complies with SGS medical-grade skin irritation testing and has a sensitization rate below 0.03%. - An optional antibacterial version is said to deliver more than 99% antibacterial performance. - YDL says fibers are refined to 1-3 deniers, creating a softer surface for sensitive areas such as joints and eye contours. - The company says semi-cross technology keeps the longitudinal-transverse strength ratio at 1.2:1 and supports 50% elongation. - YDL says the substrate remains stable after 100 folds and maintains 72-hour adhesion without edge curling. - The material is said to remove residue-free and without red skin marks. - YDL says the porous structure absorbs sweat and secretions and supports even release of active pharmaceutical ingredients. - The company says drug delivery efficiency is 30% higher than with traditional materials. - Customization options include a basis weight of 40-100g/㎡ and widths from 0.8-3.2m. - YDL says it offers the material in rolls, sheets and special-shaped cuts. - The substrate is said to be compatible with hot melt adhesive, oil adhesive, rubber adhesive, hydrogel and silicone gel. - YDL says the material avoids common issues such as degumming, glue penetration, wrinkling and bottom leakage. - The company says the product is manufactured in a 100,000-class clean workshop with full aseptic management and complies with ISO9001 quality management system and medical device-grade substrate specifications. - YDL says the product is certified by SGS, CE and FDA and has a 99.5% bacterial filtration efficiency. - The company says the substrate is naturally degradable, free of formaldehyde and fluorescent agents, and compliant with EU REACH standards.

Between the lines: - YDL is competing on substrate performance rather than finished patch branding, which suggests the company wants to serve as a supplier to patch makers instead of a consumer-facing brand. - The emphasis on multi-adhesive compatibility points to a market where manufacturers want one base material to support different formulations and reduce retooling costs. - The certifications and clean-room claims are aimed at buyers that need documentation for regulated medical markets.

What's next: - YDL says it will continue offering customized substrate support for pain plasters, herbal patches, post-operative repair patches, wound dressings, fixation dressings and functional dressings. - The company says it is seeking cooperation with global medical patch brands and plans to support international market expansion. - YDL says its production base can support annual output of more than 10,000 tons, which suggests it is built for larger-volume orders.
