0.6mm PET cut sheets available for visor production

I wondered if someone in the community may be able to help/advise me. I have c13,000 0.6mm cut sheets of PET size 354mm x 278mm that I cannot use myself due to schools being closed to visitors probably until middle of 2021 and I was advised they might be suitable for use in visor production.

Please note I am not a commercial plastics supplier - I normally run a free art project and exhibition service for primary schools and we normally frame about 10,000 children’s pictures a year (we use the PET as safety glazing) - but we have not been been able to operate since March and as i am 68 and do not anticipate being able to resume for several months have decided to retire. If they are suitable for use by someone I would prefer they were used for a good purpose rather than have to sell them for recycling

I hope this post isn’t inappropriate but am struggling to identify whether these sheets are of use to anyone. Thank you for your time
