I manufacture plastic asnd perspex products , any HEAT processing or thermoforming induces incredible stresses in certain plastics , notably those with short polymer chains (read cheaper materials) like polyprop , extruded pex and polycarbonates. Its pretty easy to see under polarised light. Vinyl is not as affected The only way to reduce these is by annealing, and that is to heat up the materials to temps below their thermosplatic points for quite long times and allow to air cool. You could put your cds in a thermofan oven at 70 degrees c for an hour or so and let em cool if you really wanted to. I also laser cut and engrave plastics , you should see what THAT does to em in regards to stress!!
