Answer 1

Answer 2

Different types of plastic will shrink, slump, and/or melt at different temperatures.
What we call "shrink plastic" is probably polystyrene (#6 recycling number) in general, but not all of those look the same or may act the same, and other types of plastic will also shrink at their particular shrinking temperatures.

If you want to use other materials instead of buying "shrink plastics," try the clear plastics that are used for take-away salads and in bakeries, e.g. (sand first like you would for other shrink plastic sheets).
Or you can shrink the foam-type of polystyrene (like foam drinking cups and plates), but those may end up thicker, etc.

There's more info on "shrink plastic" and other shrinkable, slumpable, or meltable plastics on this page of my site if you want to check it out:

Here's more info on using #6 plastic and a bit more:
