I've done this in max cloth numerous times when I was doing consumer packaged goods modeling. Stuff like hot dogs, bacon, etc. https://drive.google.com/open?id=11Y05ny...o7y_cCjMFc
I'll have to give tyFlow a try to see how it operates, but like Tyson said, negative pressure isn't really negative pressure, and sometimes I'd actually get better results inverting the normals and applying more pressure if that makes any sense.. found that out on accident after a hot dog sim ate itself lol. https://drive.google.com/open?id=1-84cWk...M8McJPucuM
I was playing around in the file and noticed that the timing on the modify binding was not set to continuous which means, if I'm not mistaken, that it is only operating once and not re-iterating over and over, which is how a real shrink-wrap works. Changing that gets something more like a shrink wrap. Is that what you were looking for? In either case, it looks cool.
The bias like Tyson said is like a rubber effect where the material is able to shear or shrink on itself. In this example it would probably lessen the wrinkles that get caught if the self-friction doesn't hold them together. Most of my shrink wrap work was with a more plastic material.
I also reduced the collision particle size because once the negative bias takes over they seem to shear weird. This seems to look good, albeit it's a little slower.
Here it is with some negative bias:
I'll attach that file next. Hope it helps.
