ODM Medical Raw Material Hydrocolloid Master Roll Yellow Star Pimple Patch

Hydrocolloid Pimple Patch rolls are core raw materials based on moist wound healing theory, widely used in personal care and medical fields. Since Dr. Winter's 1962 research demonstrated that moist wounds heal twice as fast as traditional dressings, these advanced materials have become essential in modern wound care.

These industrial-grade semi-finished materials feature a three-layer construction:

• Breathable PU film outer layer
• Hypoallergenic hydrocolloid core layer
• Protective release paper backing

The hydrocolloid layer contains CMC and gelatin within elastic polymers. When exposed to wound fluid, these particles rapidly swell to form a protective gel barrier that safeguards the skin while promoting healing.

These master rolls offer exceptional processing flexibility for both industrial and end-user applications:

• Industrial cutting into precise sizes and shapes
• End-user customization for specific wound sizes
• Recommended application: Cover area 2.5cm larger than wound
• Application technique: Press from center to eliminate air bubbles
• Replacement indicator: Change when material turns white or shows leakage
• Removal method: Peel slowly from the edge

Growing demand driven by aging populations and home care trends. Applications span daily skincare to chronic wound management. In evolving markets like China, hydrocolloid dressings are becoming key categories in centralized procurement systems, making quality raw materials essential for cost control and competitive positioning.

Future developments focus on enhanced breathability, improved absorption capacity, and expanded applications in medical beauty products.
