About CPP Outer Sleeves

Our outer sleeves are made from crystal clear cast polypropylene (CPP), a premium material chosen for its exceptional clarity, durability, and long-term performance.

CPP provides a high-gloss, ultra-transparent finish that enhances the look of your record jackets while protecting them from dust, scuffs, moisture, and everyday handling. Compared to standard poly sleeves, CPP offers superior tear resistance, resists creasing, and maintains its clarity over time without becoming cloudy or brittle.

Used in applications where optical quality and surface smoothness are critical, CPP delivers a clean, polished presentation while safeguarding your collection.

Our outer sleeves have passed the Photographic Activity Test (PAT) in accordance with ISO 18916, ensuring they are safe for long-term archival storage and will not cause album artwork or inks to discolour over time.

All sleeves are made in Canada using high-quality, North American-sourced film.
