rubber envelope

[zoran]

Do you know how this rubber/plastic/silver envelope is called? It can be sealed by heat, some have a zip lock, but this particular one is sealed when heat is applied by some thermo tool
Sorry i dont know more term specifics to guide you further.

Spoiler: wrong answer – see below

I've always called it shrink wrap.

Shrink wrap, also shrink film, is a material made up of polymer plastic film. When heat is applied, it shrinks tightly over whatever it is covering. Heat can be applied with a handheld heat gun (electric or gas), or the product and film can pass through a heat tunnel on a conveyor.​

​

I remember using it to mock up packages in college; a couple of us got carried away and tried shrink-wrapping everything we could fit.

FWIW, you can shrink-wrap water.

I wouldn't call it shrink wrap. I think of something much different when I think of shrink wrap. Though, my knowledge of shrink wrap could be behind the times.

I did a search for "plastic heat seal bags" and found a bunch of hits and you can order clear ones and foil ones on Amazon among other places.

Shrink wrap is what you wrap pallets in.

To the OP we used to just call them zip lock bags or vacuum bags.

Vacuum is not applied to the sample I attached though 😊

and i am certain that it is not a shrink wrap technology.

The closest thing I can think of is an antistatic bag. The image you posted matches the description of one, being made of PET and possessing one side with metallised film.

Looks likes an plastic zip lock bag to me. It's hard to tell from the picture but it may also be antistatic.

There is machine that uses vacuum and heat to seal heavy bags like the one shown by the OP. The name of brand is called, "Food Saver." However, to seal a bag that contains a liquid vacuum is not used, just the "seal" action by the press of a button. Most vacuum/heat sealers are designed for sealing b both liquids and solids.
