There's an easy way to straighten out (joint) the edge of wood or laminate. Very similar to this method
, You need no trim bit with a bearing. You need no template as a straight edge guide. This is a simple table/fence set up for a router.
Pretty much as the link shows, but more simply, any substrate...plywood, MDF, particle board, or melamine (which is very smooth and works well), is used as a table top. It can be 12" wide and 3' long.
Take any 3/4" substrate, 2"-3" wide, and maybe 3' long, and laminate the 3/4" straight edge with HPL (like Formica). At the middle of the 3" piece, laminate on top of the laminate another strip with 1/32" Formica. This will be the take up for what gets milled off (kinda like the outfeed table on a jointer). Trim off the mica on top and bottom.
Lay the 3" strip on the table so the back edges line up. Make a mark in the center, right where the add on 2nd piece starts. Drill a hole in the table for the router bit you will use...1/4" straight faced carbide tipped bit will do fine. Or, you could use any size bit that's straight faced, like 1/2" will work too. For that bit, drill a 1/2" hole.
Mount the router from underneath, so the bit sticks through. Turn on the router, and feed the face (with the laminate on it) slowly into the bit straight so it makes a slot further into the 3" piece than the thickness of the bit, right where the add on piece of mica is glued. Looking right at it, have the add on piece to the left of the bit.
When positioning the 3" piece, have the cutting edge of the bit line up with the right side face, and fasten the fence down. So, what you have is a nifty jointer set-up that takes 1/32" off on each pass. With the router off, and the bit retracted, take a file and put a small bevel on the add on mica, as a feed in bevel. It won't need much, just take it down to knock off the square edge.
Now, when making a pass, The stock will slide real nice, and only 1/32" will come off. You can make as many passes as necessary to get a straight smooth edge. Looking at it the feed direction would be from right to left. The bit should be turning into the wood as you push the wood.
