Dunkin Donuts paper cups are made with double-walled paperboard, which is not the most ideal material to use in the microwave. Furthermore, the paper is bonded together with an adhesive glue that can melt or leach into the beverage when overheated.

Instead of brewing a fresh batch of coffee or stopping by the store again, simply reheat the Dunkin Donuts coffee in the microwave.

Microwave ovens work by agitating water molecules with friction to create heat. Although paper cups can be designed to hold hot beverages, they are not made for cooking or reheating.

Dunkin Donuts paper cups are are sealed on the sides with glue that can melt, cause a leak or distort the shape of the cup when microwaved at high heat levels. As a result, the adhesive can leach into your drink which is not safe to drink. 

Generally speaking, microwave ovens create pockets of uneven heat and can also burn the paper when proper reheating methods are not followed. As a result, it is recommended to transfer the hot beverage to a glass or ceramic mug to reheat in the microwave.

These new designed cup have better heat retention properties compared to foam cups. Coffee will stay hot for longer, while the outside of the cup remains cool to the touch. 

Double-walled paper cups are not recommended to use in the microwave. The intense heat generated inside a microwave can melt the adhesive glues use to bond the side walls, leach harmful chemicals into the beverage, distort the shape of the cup and cause a leak from the sides.

Dunkin Donuts are continuously improving cup designs to be eco-friendly and also avoid any leak issues. However, because the double walled cups are better for the environment doesn’t necessarily mean that they are microwave safe.
