Four-flap Corrugated Board Enclosure

This type of enclosure is constructed from two pieces of acid-free and lignin-free corrugated board (E-Flute) with a Velcro fastener. The four-flap enclosure lays out flat on a table when opened and assumes the shape of a cross.

When do we use this type of enclosure?

Normally used to accommodate books which need more protection and between 2 to 4cm thick.

* Unlike other four-flap enclosures, close the full flap first (from the side).

See the short video below for handling instruction.
