No, shiny survival blankets do not help the body absorb heat.

These blankets operate in three ways to reduce the amount of heat a body loses.

Being impervious they protect against water and wind that together or separately can cool a person rapidly - perhaps towards hypothermia.

But the reason it is made of a thin metallic film (usually aluminium) apart from being easily packed into a small space is that, despite being a good conductor of heat (a bad thing in the situation), it is a very good reflector of heat helping to reduce the heat lost by the body.
