It’s about time for me to order some inner records sleeves for my vinyl collection, and I have narrowed it to three choices. All are made from polyethylene.
Mobile Fidelity Polyethylene (approx. $20 for 50): These are an old standby, but I have read some reports of them leaving a film of something on the record over time. These reports seem to indicate that it could have been from a defective batch, but I haven’t found confirmation one way or another.
sleevecityusa.com (Diskeeper Ultimate Audiophile LP Sleeve 50 Pk $26.99): These have rice paper on both sides with a cutout so that you can see the record label, vs. only one side on the Mobile Fidelity sleeves.
MA Recordings Inner Sleeves ($33 per 50 pk): These are woven from a blend of two polyethylene based microfibers. They are strong and semi-opaque and porous to avoid trapping moisture in the sleeve.
I am interested in opinions from people who have tried any or all of these sleeves as to any pluses or minuses you have found.
