Packaging material Makrofol DE1-1
Tried and Tested in a New Application
Besides its use as a medical packaging material, Bayer MaterialScience AG of Leverkusen, Germany, also recommends Makrofol DE1-1 for applications in medical technology. Evidence for this is provided by the new generation of blood and fluid warmers marketed under the brand name Fluido, which can be found in operating theaters and intensive care units. These warmers are fitted with a new type of disposable cassette with a transparent cover made from polycarbonate film. The cover is transparent to infrared light so that the cassette contents, such as blood or other fluids, can be warmed up quickly and gently in a controlled way to the exact temperature required by the patient. The cover is also impact-resistant and well able to withstand the harsh treatment routinely encountered in hospitals. Its high transparency allows hospital staff to check what is happening inside the cassette at a glance. The excellent heat resistance of the film enables the cassettes to be sterilized with superheated steam under pressure at 121°C.
The material is resistant to body fluids and so satisfies the specific requirements of the international standard ISO10993-1 on the biocompatibility of plastics. The polycarbonate also complies with the biocompatibility criteria of the US Pharmacopeia, Class VI.
