Protecting LLFP?

Was able to snatch a LLFP repress a couple of days ago and I’m very nervous of the vinyl being damaged by the PVC. How exactly do I store it? I’m assuming it will still be damaged by the PVC even with an inner sleeve over the vinyl. Will I have to bite the bullet and purchase a custom gatefold? I’ve only owned standard vinyls so I’m unsure. It’s a beautiful live album and would hate for the sound to be damaged.
