Bubble wrap can prevent heat loss due to the small air pockets in each bubble. As heat radiates, the air is heated, and the small pockets generate heat to each other. Which is how the heat is kept inside. It only escapes when the bubbles are popped.

Bubble wrap is a material used for impact absorption, the air bubbles act as a cushion for the object which is being protected as well as what the object hits.
Bubble wrap works by surrounding an object with strong cushions of air that keep the item from being damaged when it gets jostled around. Bubble wrap was invented back in 1957.
All Post-Offices, FedEx, and UPS offices sell envelopes with bubble wrap inside. This will help to keep the item you are shipping safe, and it is very cheap in cost.

Glue a sheet of bubble wrap to the inside of a mailer envelope.
No they are not lighter unless the bubble wrap in question is not filled with air, but instead of some other gas that is lighter then air. The object, if filled with air, will in fact weigh heavier, but not by any significant means.
When using bubble wrap do the bubble go on the inside or outside of the object.
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.

Air bubbles.
Bubble wrap is made up of many small pockets of air. Air is a relatively poor conductor of heat, it mostly transfers heat via convection (movement of the heated air). The bubble wrap prevents the air surrounding the object from convecting because it is trapped in the bubbles. This reduces the amount of heat which can be transferred to/from the object, thus insulating it.
