What is the difference between a plastic-core and wood-core folding table top?

Folding table tops consist of a core material covered by a surface layer. (1) Wood or particleboard core: traditional construction, provides a solid writing surface, good for laminate coverage, but absorbs moisture if edges are damaged. Standard in most commercial folding tables. (2) Blow-mold plastic core: hollow plastic construction that's very light, completely moisture-resistant, and durable against outdoor use. Surface isn't as solid-feeling as wood core for writing. (3) Steel or aluminum core: used in some heavy-duty industrial tables for maximum strength and moisture resistance. For office and event use, wood-core with laminate is the standard. For outdoor or wet environments, blow-mold plastic is preferred. FindOfficeFurniture.com — call 888-719-4960 for both options.
