Acid-free archival cardboard for creating portfolios, folders, models and boxes

We have chosen thinner archival full cardboards that are especially suitable for the independent creation of portfolios, folders, models and boxes. Their excellent grooving and bending properties come to the fore primarily due to the high proportion of long fibers and their transverse-longitudinal direction. They are made without optical brighteners and have passed PAT according to ISO 18916.

The inner side is naturally white, the alkaline buffer neutralizes acids, and the very smooth surface reduces the possibility of abrasive action. The gray-blue color of the exterior is specially refined to be resistant to dust and dirt. Cardboard boxes are effective in many ways, from providing support during manipulation to protection from atmospheric pollution.
