Self-adhering bandages (typically referring to self-adhering elastic bandages) are medical or sports dressings that adhere only to themselves, without sticking to skin or hair.
1. Working Principles
• Pressure-sensitive adhesive and microstructure: The surface is coated with a special hypoallergenic, pressure-sensitive adhesive. It does not stick to ordinary objects (such as skin, hair, or clothing); however, when layers are wrapped and lightly pressed together, the like materials bond firmly (or "interlock" via microscopic fiber structures).
• High elasticity and stretch: Typically composed of non-woven or cotton fabric combined with spandex fibers, the material offers high elastic elongation (180% to 220%), allowing the level of compression to be adjusted by varying the stretching force during application.
• Convenience: No adhesive tape or scissors are required; the bandage can be torn by hand.
2. Application Scenarios
• Sports protection and first aid: Used to protect joints (such as ankles, knees, and wrists) during activities like running or ball sports, or for temporary compression bandaging following sprains or soft-tissue contusions.
• Medical and post-operative fixation: Used to secure wound dressings, gauze, medical catheters, IV cannulas, or splints.
• Veterinary care: Commonly used for bandaging wounds or securing IV catheters on pets (such as cats and dogs); because it does not adhere to fur, removal is relatively painless.
