As the trends toward miniaturization, portability, improved aesthetics, and environmental responsibility drive ongoing changes in medical devices, selecting the right materials has become more critical. Owing to plastics’ comparatively light weight, low cost, ease of processing, flexibility and superior biocompatibility, medical plastics have become an integral component in a wide range of modern medical devices and supplies, covering disposable syringes, intravenous blood bags, heart valves, etc. To achieve optimal product usability, appearance, endurance and performance, plastics are one of the best options for medical device designers. Plastics are also particularly suitable for medical packaging due to their exceptional barrier properties, light weight, low cost, durability, transparency and compatibility with other materials. Without doubt, modern healthcare would not be possible without plastics technology.
