Are there any PVC-free sleeves that would allow to have two mint sets to a page in a binder?
Lots, assuming you have a heat sealer. Otherwise you're limited to a couple of branded 2-pocket pages, like UltraPro to name one. But if you have a sealer, go get some A4 pages from OfficeWorks or whoever and go to town on them.
Thanks Fulvio. Do you know any of the other brands besides UltraPro?
I've not taken a lot of notice, to be honest, since I had a huge pile of pages from a previous life. But I've seen others mention them here a few times, so I'm sure someone will pipe up soon enough. :)
Can you buy PVC free A4 sheets and use a heat sealer to make bespoke sleeves to suit any situation?
Definitely. Any thermoplastic will work in heat sealers. Just adjust the temperature and time to suit the material.
