I bought a pack of blank Philips DVD+R discs last week, opened them to put them on a spindle and they reek of cooked celery. I bought a pack of RiData blank mini DVD-R discs and opened them, and they also smell like celery. It's a strong smell. I had the same thing with a lot of Philips DVD=R discs I bought in 2011- that same strong smell of celery.
What causes this? Is there a chemical used in their manufacture that has this smell? I never had an odor with blank CDs but since I started getting blank DVds I've noticed strong odors that remind me of cooking celery- and the bigger the pack, the worse the odor.
