Mylux Vault Mylar 12" Vinyl Record Outer Sleeves – Resealable

Crafted from genuine, ultra-clear BOPET (Biaxially-Oriented Polyethylene Terephthalate), the Mylux Vault delivers protection above and beyond standard polypropylene outer sleeves. This is the chemically similar to the archival-grade BOPET commonly sold by DuPont un the Mylar brand. Prized by serious collectors and previously only available from specialist US manufacturers – now engineered specifically for 12" vinyl and sold in Australia! While everyday polypropylene outer sleeves inevitably wrinkle, cloud, and off-gas over time, Mylux Vault BOPET is engineered for eternity. It guarantees zero degradation and no yellowing, so the album jacket underneath stays as vibrant and pristine in fifty years as it is today. At a substantial 4 mil (approx. 100 micron) thickness, this is our heaviest-gauge sleeve – completely non-stretchable and built to withstand the daily handling that destroys ordinary outer sleeves. It holds its rigid, high-clarity shape to defend gatefold and single jackets against ring wear, seam splits, spine creasing, and corner dings on the shelf. Note: This is the Resealable version, finished with a 328mm x 328mm + 38.1mm self-sealing flap for a fully enclosed, museum-grade seal. Prefer an open slip-on fit instead?
