What is the life expectancy of duct tape?

The life expectancy of Duct Tape varies depending on factors such as the environment and conditions in which it is used. Generally, standard duct tape can last for several years when stored properly, but its adhesive properties may degrade over time, especially when exposed to moisture, extreme temperatures, or UV light. In ideal indoor conditions, it can last up to five years or more, while outdoor conditions may reduce its effective lifespan significantly.
