record inner sleeves

Inner sleeves are commonly made from combinations of paper and HDPE. Listings often describe 3‑ply constructions with an anti‑static rice paper layer sandwiched between HDPE plies; plain acid‑free paper sleeves are also offered.

Most inner sleeves are listed for 12" LPs and are described with 12" × 12" face dimensions. Some listings specifically note fit for 10" records.

Inner sleeves typically come with square or round corners. Round corners are said to reduce snags, jams, and hang‑ups compared with square corners.

Some inner sleeves are labeled archival quality, anti‑static, and acid‑free. Others use HDPE layers combined with an anti‑static rice paper layer to limit static and help prevent label deterioration.

Common lining options include plain paper sleeves, paper sleeves with a soft poly or HDPE lining, and full 3‑ply constructions where a paper layer is sandwiched between HDPE plies.

Most inner sleeves are sized for a single 12" LP. Some listings describe larger outer or protective sleeves that are slightly bigger and can accommodate single records, double discs, heavier 180–200 g records, and gatefold jackets, but this is not true of standard inner sleeves.

Opening styles include an easy‑open lip, a resealable flap with tape closure, and resealable retail packaging designed to keep sleeves organized.

Many listings state that sleeves help prevent static build‑up that attracts dust and dirt. Some sleeves combine anti‑static layers or an anti‑static rice paper layer with HDPE to further limit static.
