A method of manufacturing sheeting is provided, the method including the steps of forming multiple recesses in a symmetrical repeat pattern on a sheet of material, extruding a molten material to form an upper outside wall and a lower outside wall, interposing the formed sheet between the upper outside wall and the lower outside wall, and fixing the interposed sheet to the upper outside wall and the lower outside wall. Also provided is sheeting having an upper outside wall and a lower outside wall and an interposed sheet fixed between the outside walls. The interposed sheet includes multiple recesses in a symmetrical repeat pattern, where the upper and lower outside walls are, or the interposed sheet is, manufactured from a material which includes a polymeric material.

The present disclosure relates to an optical functional film for a head-up display, having two or more slow axis zones different in slow axis angles in the same plane, wherein a maximum difference between slow axis angles is more than 5° and less than 30°.

Described herein is a multilayer microporous film or membrane that may exhibit improved properties, including improved dielectric break down and strength, compared to prior monolayer or tri-layer microporous membranes of the same thickness. The preferred multilayer microporous membrane comprises microlayers and one or more lamination barriers. Also disclosed is a battery separator or battery comprising one or more of the multilayer microporous films or membranes. The inventive battery and battery separator is preferably safer and more robust than batteries and battery separators using prior monolayer and tri-layer microporous membranes. Also, described herein is a method for making the multilayer microporous separators, membranes or films described herein.
