Most of the plastic have materials that help in prevention of evaporation it act as a shield so that water does not gets fade away. That why plastics are being used as a prevention methods for storing food articles & save them spoiling. One of the common example are zip in pouches that most of us must have used at some point or other to store food items in refrigerators.
There are many types of food wrapping such as plastic wraps, aluminum foil, etc. However, many of them are not microwave safe. Most [if not all] kinds of plastic wrappings will melt if put in the microwave. Aluminum foil is actually a metal, so that is a definite no-no for the microwave.
The only thing I suggest if you want to microwave food in a wrapper is wax paper. However, even some types of wax paper might not be suitable for the microwave. Your best bet is to use a bowl/plate that you know is microwave-safe, or use a paper towel under your food. Nothing will happen to the paper towel if you heat your food correctly [in a suitable time frame].
And of course, make sure your food is in an OPEN container/wrapping. Closed containers can cause it to explode as the steam that is created might force the container lid open. Keep it open [this includes wrappers, don't wrap the food so tight] and let the steam come out to avoid any explosions.
None, plastic wrap gives off toxic fumes when heated. Use pure white paper towels, wax paper or parchment paper.
If the package says it is microwaveable....some of the older packages were not.
you use plastic wrap for covering something.
if you want it to melt then yes, but otherwise no No it will melt. --- There are special kinds of plastic wrap that can be used in a microwave. However, I often use normal plastic wrap to cover up a bowl with soup when warming it up in a microwave and it does not melt at all. It gets a little soft but that's it.
Plastic wrap is good to use to retain steam and nutrients in microwave cooking. There are also lids specially made for this purpose.
For freezing, it's best to use plastic wrap or freezer wrap. You can also use zip-lock baggies. Tin foil works in certain instances but you would want to use the meat sooner than if it was wrapped in plastic or freezer wrap.
The best type of plastic wrap for you would be reynolds wrap. It has a strong hold and works very well. I would recommend buying rolls of it in bulk to save money since you will be using a lot.
Most plastic bowls are safe in the microwave. It is best however to check before use as some will melt. On the bottom of all plastic dishes it should tell you if it would be safe.
A plastic lid works best. If you can't get to that use aluminum foil or sealing wrap.
You can reduce using plastic wrap by using Tupperware. It's okay to use reusable plastic because it can be recycled, whereas plastic wrap cannot.
NO
Yes, yes, yes!!! It's the only plastic wrap I will use. Glad doesn't stick. Reynolds is wonderful. I agree that Reynold's has the bet plastic wrap, but unfortunately the company has discontinued it :( http://www.reynoldspkg.com/reynoldskitchens/en/info_page/Product_Locator.asp
A piece of wax paper always works well, as does a paper towel or small plate or saucer or a larger bowl to use as a domed covering. Never use plastic wrap as it will melt and ruin the food.
