Our fridge has two white plastic shelves on the door. Both are cracked in the bottom - one just around the center, and one where almost the entire bottom has cracked along the front. I'm not entirely sure what kind of plastic they are made of - I'm guessing polystyrene because they have PS stamped on the bottom, but that's just a guess. They are off white plastic.
I've looked up replacements for them, but they are more than I'm willing to pay.
What's the best way to repair them? I've seen plenty of questionable methods searching for solutions, but no good ones. I'm not sure what kind of (easily available, something I can pick up at a big box store) adhesive I can use to glue them back together, that will hold under the weight of things we put in the shelves.
I'm guessing superglue and hot glue won't work at all. I considered wrapping the whole thing in white duck tape...but the wife acceptance factor on that solution is quite low :) Perhaps JBweld epoxy?
