1. A shaker screen assembly, comprising:
a support frame that defines a frame opening, said support frame having a top frame surface and a bottom frame surface opposing said top frame surface; and
a screen subassembly attached to said support frame, said screen subassembly, including:
a planar panel having an upper panel surface, a lower panel surface opposing said upper panel surface, a panel peripheral sidewall connecting said upper panel surface and said lower panel surface together, a plurality of undulation sealing tabs attached to said planar panel and extending approximately perpendicularly with respect to said upper panel surface and said lower panel surface, and a plurality of panel perforations extending through said upper panel surface and said lower panel surface; and
a mesh section attached to said planar panel and including at least one mesh layer, said mesh section having a top mesh section surface, a bottom mesh section surface opposing said top mesh section surface, a mesh section peripheral edge connecting said top mesh section surface and said bottom mesh section surface together, and a plurality of mesh section openings extending through said top and bottom mesh section surfaces, wherein said mesh section peripheral edge includes a first side and an opposing second side and said mesh section includes a series of undulations extending from said first side of said mesh section peripheral edge to said second side of said mesh section peripheral edge, each of said undulations including an elongated base portion and an elongated raised portion, and wherein said mesh section is attached to said planar panel such that:
a) said mesh section openings are positioned over said panel perforations;
b) said elongated base portions of said undulations are attached to said upper panel surface;
c) said elongated raised portions of said undulations form a series of elongated open areas positioned between said upper panel surface and said bottom mesh section surface and extending over said panel perforations from said first side of said mesh section peripheral edge to said second side of said mesh section peripheral edge, each of said elongated open areas having a first open end and a second open end opposing said first open end, each of said first and second open ends being positioned adjacent to said panel peripheral sidewall and mesh section peripheral edge; and
d) an undulation sealing tab of said planar panel is positioned in each of said first and second open ends of said elongated open areas.
