This enables us to reduce the filling depth of a KS 3 clamshell box 50 x 35 cm from the previous 25 mm to => NEW 20 mm. As for the KS 16 telescope type storage boxes the minimum filling depth can be reduced more significantly: By using the F 1.3 mm corrugated board we can reduce the currently/previously valid 30 mm minimum filling depth to => NEW 20 mm* (depending upon the surface grammage). F.1 mm corrugated board is also extremely suitable for making expansion folders with or without flaps (made from a single sheet) or for folders with fabric hinges - it provides form-stablity whilst consuming less space.
The Corrugated board F 1.3 mm is guaranteed to be ageing resistant in accordance with the ISO 9706 standard. The base board material is natural white, the top ply is made from grey-blue archival board 300 gsm with a specially treated top surface, dirt-resistant, erasable and rub-proof (dry wiping). Each individual ply is glued using a moisture-proof adhesive.
* Naturally we can also make boards of a smaller size & lesser filling depth from thicker corrugated board grades, however we would recommend and advise only constructions and minimum filling depths that are practical: KLUG products should be easy to handle, and yet have high stability, so as to optimize their protective functionality and ensure long-lasting satisfaction when using them.
