You could try Cloth and Shape key function to get a wrinkle:
Hey.
I made a test. Basically you start with subdivided cube. Use torus for pinching the ‘bag’ and use force to blow the bottom part.

i want to know why using collision and force field…? this tricks is GOOD…i want to try it, but cube (you created) can “expand” scala will worked?
i did try cube to expand… not work …why?
Bake the simulation…
Select cube go to Phisics tab, cloth and under cache press bake.
That should do the trick.
- Self colosion and colision on cloth…
- Torus needs colision for cloth interaction
- Force field to blow the ‘bag apart’

Hello, I’m wondering if I may ask/see this file? I’m trying to achieve the wringkle on the bag like you made but to no avail. Or maybe a step by step to make it? I tried to follow your way but didn’t seem to work the same like that, I’m not sure where I did wrong. Thanks in advance…
Its been a long time I did this. I will take some time and make another file and share it.
Oh i see… Sorry for troubling you. Though it would be nice if you can, but if you can’t, you don’t have to do it… This is what I did. I couldn’t get that shape like yours, so I just manually crease it one by one, and it didn’t look as nice… 
Haha… But thanks for responding to my post… 
Hey. Since I have made it before reading your last post I can nevertheless upload it.Bag_sim.blend (2.8 MB)
