Zaba Zoetrope Plastic Sleeve

Just got my Zoetrope copy of Zaba, and just like everyone else I was disappointed to see it shipped in a plastic sleeve.

My first question, is it safe to store the records in this plastic long term? I feel like I read somewhere that certain plastic sleeves can damage records if stored long term?

And secondly, has anyone found a cardboard sleeve to put these records in? Seems like there's a market for someone to print a sleeve that matches the art on the vinyl.
