Are these envelopes heat resistant?

Unfortunately, these envelopes are NOT heat resistant. :-( I use Stamps.com for a lot of my postage needs, so will print the postage onto a label, then trim that label to fit on these envelopes. I'd only go thru the trouble to do this IF I wanted a "date" stamped on my postage, like for a mortgage payment, etc. Still, you'd be hard pressed to find a better deal for general usage. Hope this helps, Howard

They are. The package has the usual "be careful that you don't set the paper towel on fire" warning, but nothing else re: microwaving

Keep these away from your stovetop, they are not heat resistant at all. I can't really complain since they are inexpensive and are made of plastic. Just be warned.

Yes. These have been through the high heat of the dishwasher dry cycle without issue.

No. These are very good extentions for the price of them but they do not handle heat well.

Yes they are. I have had them a long time and they are very durable and dishwasher safe.....they do get hot in the mocrowave though.

I have had no problem using them on high heat. This is a fine set of cookware.

Certainly, with proper address and adequate postage... But this doesn't mean it is smart to do so. Keep in mind they are transparent, so the contents of the envelope will be visible to people you don't even know! And the envelope doesn't seal closed.

It is my understanding that they are not fully heat resistant. That is why I originally ordered them. If you are looking for hot pads, these are not them. Rather, they are mats to set things on with a small measure of heat reisistance.

Yes! These plastic envelopes have a very secure adhesive, easily accessed by pulling the tab off. Several times i have needed to remove something and was able to reseal each one without a problem. A great product and makes all your endeavors look very professional!

Yes. They are lined with a quilted type of material. I have used these gloves for moving extremely hot items and have never even felt a slight uncomfortable temperature. Love that you can just put a little dish soap and hot water on them to clean off any grease or food if you need. Then just towel dry. Liked these so much I bought a 2nd pair for our trailer. I highly recommend them!

I think they would withstand the heat. I don't know if the size is right but heat wise, yes. I don;t think there is anything saying they wouldn't.

It's listed as. I didn't use heat on it though I'm sorry. The fibers are thick and smooth like heat resistant normally are

...Not sure about the 2.8 ml thick---but if that's the norm for these envelopes, then they probably are. I've received several items (from different venders) mailed in these envelopes, which prompted me to order some. Yes, they do have a sliverish lining to insure privacy.....Certainly are tear-proof & it would require definite intent + a sharp tool to puncture the envelopes.

They do have a heat rating. I assume if you keep it under the correct temperature you should be ok.

I think they can withstand heat; just not from cold to hot. I think most glass is like that.

No. They are flat plastic "envelopes." They tear easily and the adhesive closure does not hold.I can't trust anything I would send in them would arrive. Exceptionally poor quality for the purpose.
