Coextrusion is the process of pressing two or more materials into a single piece of tubing.
Coextruded tubing is commonly used in the packaging and medical device industries. For example, multi-layered extruded tubing can be used for drug delivery applications, including insulin delivery, angiography and pain therapy.
Coextruded tubing can also be made into a catheter or to form dual layer tubing. Each tube can be covered with different coatings, such as lubricious or hydrophilic, depending on the application.
