Gelfoam was first marketed in 1945. It is a sterile gelatin foam that promotes blood clotting and thus stops the bleeding from a wound or surgical procedure. It has the distinction of being the oldest product still being manufactured at the former Upjohn (now Pfizer) Portage manufacturing plant. This means it has been in production for 79 years. 

Gelfilm is a gelatin implant which has a rubbery consistancy and can be easily cut to a desired size and shape. It is often used in neurosurgery, thoracic and ocular surgeries. Photos of different Gelfoam and Gelfilm packages are shown below.
