High Pressure Processing (HPP) is a cold pasteurization technique by which products, already sealed in its final package, are introduced into a vessel and subjected to a high level of isostatic pressure (300–600MPa/43,500-87,000psi) transmitted by water.

I have 2 questions and somehow i am not able to understand below mentioned.
1) how is it possible to pressurize a plastic container bottle(As in the video) without collapsing the container?
2) what happens if we use a plastic polyethylene bag of juice instead of bottle?Will that bag also sustains such a huge pressure?
