In the ever-evolving medical device industry, pressure-sensitive adhesive tapes are ubiquitous in their applications. Whether in surgery, wound care, incontinence management, monitoring, or diagnostic products, pressure-sensitive adhesive tapes often serve as a primary or even critical component.
With the continuous advancement of medical technology and new materials science, the variety of medical products is increasing, not only to meet the functional needs of healthcare professionals but also to prioritize patient comfort.
Given that pressure-sensitive adhesive tape products are widely applied on the skin's surface, considerations from both medical staff and patients demand that these products not only have excellent adhesive properties but also minimize their impact on the skin to the greatest extent.
The quality of medical pressure-sensitive adhesive tapes on the market varies greatly. To determine the quality of a pressure-sensitive adhesive tape, the following points are essential.
1. Must comply with biocompatibility evaluation
Pressure-sensitive adhesive tapes come into contact with human skin, so their safety must meet the international standard ISO-10993*** sections: recommended evaluation tests covering comprehensive safety and efficacy assessments, including cytotoxicity, primary skin irritation, and guinea pig skin sensitization. For safer hypoallergenic medical adhesives, more rigorous tests such as the 21-day cumulative human irritation test and human repeated insult patch test (Draize sensitization test) are also required.
2. Functionality must meet clinical usage requirements
For medical tape products, it is necessary to test properties such as initial tack, holding power, and peel strength to ensure they meet clinical usage requirements.
Of course, in addition to being able to adhere well, current development demands also require increased comfort—both in terms of comfortable application and easy removal, which are the hallmarks of high-quality tape.
3. Minimize the impact on the skin to the greatest extent
The structure of medical adhesive tape includes adhesive and backing. Different materials used for the adhesive and backing can have varying effects on the skin. Improper selection of medical adhesive tape may lead to the following common skin injuries: epidermal stripping caused by excessive stickiness, allergic reactions triggered by sensitivity to the adhesive or disinfectant, and skin maceration due to poor breathability.
Since human skin conditions and usage scenarios vary, the selection of medical pressure-sensitive adhesive tape should be based on various factors. The adhesive strength of the tape is not necessarily better when it's stronger, and considerations such as breathability and elasticity must also be taken into account when choosing the backing material.
No single medical tape can cover all conditions and all patients, but during the tape design and development phase, it's essential to make targeted choices regarding adhesives and backings. Even two products that appear similar may exhibit significantly different performance due to variations in design.
Choosing well-researched and designed products can minimize the damage that adhesive tape causes to the skin.
In the product design process, selecting the right raw materials is a crucial task and often becomes a key factor determining the success or failure of the product. Medical tape plays a vital role in determining whether the product is effective.
The editor recommends using Hongling Design's coral-type water-based pressure-sensitive tape. Hongling tape has not only obtained the SGS biological safety evaluation certificate, ensuring the product is non-toxic, harmless, and zero-level sensitization, but also features comfortable and easy peeling, removable without residue. It is suitable even for very fragile skin, making it a high-quality and user-friendly medical tape.
