I can imagine that polypropylene has a strong elasticity, allowing it to be pierced with a syringe filled with the solution the vessel or beaker should be filled with. After filling, the syringe can be pulled back, after which the plastic film closes the hole poked into it due to its elastic properties. I cannot confirm whether this is the case with your polypropylene film, but I am quite sure I remember having seen containers stretched with plastic being pricked with a syringe when I was in my first year as a biology student.

Notes to answerer
Asker: that sounds reasonable, but how do you fill the beaker if it has film over it?
