Product information

Airvelope® hybrid enclosure for storage of paper

Description

Innovative hybrid enclosures Airvelope® 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 breathable, acid-free 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 archival storage of paper. It makes it possible to see the contents without taking them out.

Types of enclosures: 
L-type enclosure - 2 edges are sealed 
U-type enclosure – 3 edges are sealed
„sleeve” – 2 parallel edges are sealed
