Disclosed is a closed-cell, non-crosslinked foam structure of a ratio of min or dimension to major dimension of 1/8 or less comprising a plurality of coalesced extruded strands or profiles of a foamed polyolefin composition having an average cell size of from 0.02 to 0.5 millimeters. The cross-sectional geometry of the foam structure substantially corresponds to the overall arrange- ment of the orifices of the die from which the foamed polyolefin composition was extruded. Further disclosed is a process for making the above foam structure comprising extruding a foamable polyolefin composition through the multiorifice die to form the structure.
