Let's start with the basics of foam boards: what they are, what they are made of, what functions they offer, and what sizes they come in.
A foam core is a display and printing material consisting of a dense foam core sandwiched between two sheets of matt paper. Foam cores are usually made from polystyrene, one of the most common types of plastic in the world, which is also used in the manufacture of polystyrene foam. Because the polystyrene core of a foam board is 95-98% air, the foam core board is very light.

Printed foam core signs and boards are ideal for display items to convey that message at your business event. These high-quality boards are best suited for business or academic presentations, lectures, and trade shows. Businesses often create custom foam board signs for special events or to advertise sales to customers.
There is no difference between foam core and foam board; they both refer to printed and display boards made from a foam core between two sheets of paper. You may also see this material referred to as foam core, foam board, paper-faced foam or kappa, depending on the manufacturer and region.
One source of confusion about this terminology may be alligator board, a different printing and signage material that also has a foam center. However, the difference between a gator board and a foam core board is that the surface of the gator board is made of wood fiber veneer.

The foam core has many useful properties that make it one of the most versatile materials used for signs and displays. The following are some of the material's distinguishing features.
Heavy-duty poster board - In contrast to other types of poster board, which are usually ductile and do not have a solid core, foam cores are very strong. The foam core is rigid, can be laid flat on its own, stays straight when supported or hung, and resists bending and curling. This is the material to use if you need a rigid poster board.
Super light - although foam board may be slightly thicker than other types of poster board, there is little difference in the weight of the foam core. Foam core boards are very light, which means they can be easily transported, displayed, and stored.
Easy to print and cut - foam core board is a great material for printing and cutting. Photographs and designs can be printed directly onto the foam core and the boards can be neatly trimmed to almost any shape.
Multiple finish options - you can easily choose to laminate or frame your foam core panels. You can also find foam core boards with a variety of finishes, from glossy to textured to matt.
Low cost - foam core panels are some of the cheapest printing and display materials on the market. Their low cost makes foam panels ideal for short or large projects.
