Wide white background for school groups

[rgrebby]

I've been asked to do some school class photos. They want them on white infinity.
I'm thinking portable rolls and stands but wondering if they will be wide enough. Ideally needs to fit in my car and a think a 2.72m roll will fit.

Any suggestions?

id ask if there is a drama / classroom with a white background , then just back light them? sort it out in post production??

Sadly there isn't. Thought of that already.
