Polymeric films are used in a variety of medical applications. These include disposable surgical gowns, mattress covers, fluid bags, transdermal patches and wound-care products. Films can be used in single-layer or multi-layer constructions, and can be manufactured from a variety of materials ranging from non-porous PVC to breathable polyether block amide copolymers (Pebax®) as well as high barrier polyamide polymers (MX-Nylon) and even polyolefin copolymers (TPX™)
PVC is a material of choice for many film applications used in this construction of medical bags. These include:
- Intravenous (IV) bags
- Blood bags
- Nutrition feeding bags
- Dialysis bags
Moisture-Vapor Transmission Fabrics
Moisture-vapor transmission (MVTR) properties are critical for many applications that require breathability of the fabric, such as gowns or wound care dressings. Pebax® MV 1074 SA 01 MED is a naturally hydrophilic polymer with excellent permeability to moisture vapor while remaining waterproof. Pebax® can be laminated onto synthetic nonwovens, wovens or any textiles with the help of some functional polyolefins, and does not require any adhesives or bonding agents to adhere with these substrates.
