What Are Bar Coasters Made Of?

The vast majority of bar coasters you would see from your favorite brands are made of recycled pulpboard paper and printed using offset or digital methods.

Pulpboard is a type of thick, rigid paperboard made from compressed paper pulp. It is commonly used for various packaging and printing applications due to its sturdiness and ability to absorb ink well. Pulpboard is manufactured from layers of paper pulp that are pressed and bonded together to create a dense and durable material.
