Expanded Polystyrene foam offers a broad range of physical properties to allow packaging designers to meet the challenges of protection and distribution. These properties, in combination with appropriate engineering design considerations, provide the design flexibility required to create truly cost effective protective packaging
This is an economical packaging foam that is available in densities ranging from 1# to 3# and is easily formed by cutting, hot wiring, molding and routing.
