Looking for an acid-free protective cover for training certificates, diplomas and awards?

storage.boutique has developed an innovative, lightweight archive sleeve designed specifically to protect A4 size (300 x 214 mm) certificates. These sleeves are available in packs of 40 or 100 individual sleeves. As you would expect, all storage.boutique sleeves are acid free. In addition, all storage.boutique sleeves are manufactured from a triple layer film - protecting from the damage caused by ultraviolet light, moisture and acid. Our sleeves are coated on the outside layer of the three layer film to retard the harmful effect of ultraviolet light. The middle layer is a dense core which prevents tearing. The inside layer of our sleeve is made from an untreated material which ensures that the sleeves are completely acid free on contact with your precious certificate. Our sleeves are sealed at the edge by compression and ultrasound, meaning that they fit neatly around your certificate, putting the focus on the contents. The new technology material does not dull or scratch over time and retains the crystal clear transparency that you want for your documents.

storage.boutique sleeves are perfect for keeping awards clean and crisp. They are ideal for training companies and educational establishments, offering a far more professional display than simply card or traditional polypockets. Our sleeves retain crystal clear transparency for decades and will make the certificate inside the sleeve look as if it had been freshly issued. Gone are the days of tired looking and wasteful plastic polypockets!
