Clear PETG

PETG (Polyethylene Terephthalate Glycol) has high Impact strength and is reasonably flexible. It can be formed with and without heat although tight bend radii could result in splitting and stress marks on along the folded edge. Caution is advised for very detailed, intricate cut outs & large areas of engraving as the build-up of heat can cause the sheet to deform. Line engraving is favored over area engraving and intricate details are not recommended.
