The HANDY CODER is a handoperated machine that can be used to mark or code on corrugated cartons, plywood, wooden crates, paper bags, cement asbestos sheets, leather cloth or any substrate that absorbs ink. A non-porous variant can also be used to mark on nonabsorbent substrates such as metal and plastic drums, HDPE woven sacks etc. The Handy Coder can effectively mark on an area 95 mm in width and 355 mm in length.
