When admitted to a hospital, patients receive IV fluids. Generally, IV fluids are packaged in flexible plastic bags.
They are lighter and break less than glass bottles, and are easier to move and store.
Plastics used for medical use require more stringent standards because they are directly linked to our health.
Especially since IV fluid bags undergo a high-temperature sterilization process, they must be safe and heat resistant.
Transparency must also be high to ensure that the speed and condition of the IV being administered are clearly visible.
They also need to fulfill multiple properties, such as being flexible and impact-resistant.
This is the reason polypropylene (PP) is used as the material for IV fluid bags.
PP is one of the most widely used general-purpose plastics that can transform into various products depending on the properties and processing method.
With excellent tensile and impact strengths, it is used in a wide range of applications, including films, textiles, and automotive parts.
