I was watching drive ins diners and dives on tv they covered a meatloaf with plastic wrap then alum. foil to bake. Is this special kind of wrap?

It's highly unlikely they used plastic wrap to wrap the meatloaf before aluminum foil. Here's why:

* Safety: Plastic wrap is not designed for high heat. It can melt or release harmful chemicals into your food when exposed to oven temperatures.

* Functionality: The purpose of wrapping a meatloaf is usually to help it cook evenly and retain moisture. Plastic wrap wouldn't provide that function in an oven.

What they likely did:

* Directly in foil: The most common method for baking meatloaf is to wrap it directly in aluminum foil. This helps create a steamy environment that keeps the meatloaf moist and cooks it evenly.

* Pan and foil: They might have placed the meatloaf in a baking pan, then covered the entire pan with foil. This is another way to ensure even cooking and prevent drying out.

It's important to note: If you're ever unsure about cooking techniques, it's always best to follow a trusted recipe or consult a reliable cooking resource.
