You've got a dense thick black absorber versus what is essentially a thin flexible mirror. Granted there are other forces in play here but it's a no brainer that the thin reflective layer will have a cooler result. I would have figured a more fair comparison would be a thin white control, white paper or white thin plastic bag perhaps. Granted the aluminized mylar should still perform better than a white body but the difference won't be as dramatic as your homemade solar collector control.
