Para film keeps out dust and "critters" and does have some breathing
capabilities though I'm not sure if has been documented and will differ with
the number of layers of Para film you use.  People also use surgical tape,
saran wrap, Nescofilm, micropore tape, florists tape, Austraseal, etc.
Breath ability differs on all of these and documentation is limited.
Austraseal is advertised as having better breathable characteristics but
again documentation is limited.  Make a nice master's student project???

greetings all,

i wonder why we use a parafilm after capping test tubes filled with media
and cultured explants?

is parafilm even sterile? does it allow gas exchange ?

thanks

best regards
