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 Pebax®, as well as high barrier polyamide polymers, such as MX-Nylon and even polyolefin copolymers, including 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

Medical Gowns & Moisture-Vapor Transmission Fabrics
Moisture-vapor transmission (MVTR) properties are critical for many applications that require breathability of the fabric, such as surgical gowns and 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.
Polyurethane (TPU) film also offers a unique set of properties that make it an excellent choice for medical fabric applications as well,including gowns, drapes, gloves, sheets and pads. TPU offers antimicrobial properties, breathability and biocompatibility, all while maintaining elasticity and a soft to the touch feel. TPU films are also resistant to skin oils and have excellent tear and abrasion resistance.
