Can I reheat a sauce in a squeeze bottle?

Question

I have some sauces held in squeeze bottles: Low Density Polyethylene (LDPE), recycling code 4, dishwasher safe.

I want to stand them in hot water. Is it safe all the way to boiling point or does LDPE start to deteriorate at a lower temperature?

Thanks

Answer 1

Britannica says LDPE is OK to 110°C but that would leave it pretty close to collapse if it were allowed to touch the pan itself with a burner underneath.

I'd also consider how floppy it might be at 95° or so.

I'd perhaps think of another method.
