it keeps things cold by not letting the molecules or the coldness escape
All food goes off due to bacteria, if the food is shrink wrapped, then it will stop a lot of bacteria getting to it.
It stops the heat from going out of whatever you have wrapped in it
Bacause material used in it does not allow the heat to pass through it
Tight wraps and covering decrease the rate of oxidation (or ripening).
I usually use plastic wrap ( glad wrap) because it isn't as bulky and it's more air tight. So no it doesn't keep meat better than plastic wrap.
It is an insulator. It would take many wraps to make it become a good insulator. There are much better products in the market place to use for insulation purposes which are much safer.
It would definitely have to be plastic wrap because plastic wrap is an insulator, which aluminum is not.
Plastic is an insulator.
Bubble wrap is better because it contains air, which is a very good thermal insulator.
yes plastic is very good insulator
It is not a good insulator if you are dealing with temperature because of the air pockets and the temperature of air inside a bubble (air pocket) but it would be a good insulator if your dealing with something related to circuits because plastic is not a conductor.
No, glad wrap is not a good insulator. There are other materials used in which are much better at insulating than glad wrap, such as aluminium foil or wool.
A good insulator would be rubber or plastic.
insulator
Air bubbles.
Depends what you are insulating against but bubble wrap can be good a insulating.
It seels it the best.
