Even though knowing the model of printer is slightly helpful, it's not critical to making your print work. Your PLA manufacturer should have recommendations for both the bed temperature and the nozzle temperature. Is your print bed glass or metal?
As an example, my bed is glass and I set the temperature to 70°C for PLA, but the real temperature at the bed is slightly lower than that.
I'm using 3M brand blue painters tape. What type of tape are you using? It will make a difference. I originally used cleaner on the tape, but found it was not needed. Blue tape means parts stick so well that you have to get them free before the bed cools too much, or you'll have to remove the tape to get the part free.
My PLA nozzle temperature settings range from 190°C to 230°C, depending on the filament. I use the manufacturer's figures and vary them five to ten degrees depending on the results.
Too hot at the nozzle will burn the filament possibly causing a clog, while too cold will cause extruder feeding problems. You did not reference having feeding problems, which implies your nozzle settings are acceptable.
Consider to change your tape and to increase the bed temperature. At a 55°C starting point, you could jump five degrees at a time until you get a good bond.
Also be certain that your bed is level and properly calibrated. The first layer should apply in a slightly "squashed" manner. Too close and the nozzle tears up the tape, but too far and the filament will sit on top and not properly adhere.
