About CPP Outer Sleeves
Our outer sleeves are made using crystal clear cast polypropylene (CPP) to protect your record jackets from scratches, dust, moisture and more. CPP offers a higher tear resistance than other films, is very hard to crease and won't turn cloudy over time. It is typically used in applications that require superior optical properties, such as gloss, transparency and surface smoothness. Outer sleeves have passed the photographic activity test to meet ISO18916; they won't cause your album covers to discolour over time.
All outer sleeves are made in Canada using pure film from North America.
