Airvelope® Clip hybrid enclosure

The latest version of the innovative hybrid enclosures, Airvelope® Clip is an enclosure with separate pockets and holes for clipping into a binder. This solution makes it fast and easy to look through the collections. Hybrid enclosures combine best qualities of two different materials: the front cover is made of perfectly transparent and chemically inert Melinex polyester, whereas the material used for the back cover is PAT-certified breathable, neutral cotton paper. No adhesives are used to produce our hybrid enclosures; the two materials are sealed by means of ultrasonic sealing technology.

This enclosure is designed for the storage of photographs and negatives and makes it possible to go through the contents without taking them out.
