Properties of cardboard honeycomb panels

Honeycomb cardboard panels - like the sandwich panels filled with plastic foam - combine two extremely positive material properties: they are light and yet stable. The following measuring result shows how stable the cardboard honeycomb panel is: a cardboard-clad panel supported on four sides and measuring 20 x 500 x 800 mm bends 6 mm at most when loaded centrally with a weight of around 100 kg. The same plate is pressure-resistant up to a load of 35 to 40 tonnes per square metre! In other words: an area of 10 x 10 centimetres can be loaded with 350 to 400 kg.

The cardboard honeycomb panel is actually used as a material for the manufacture of disposable pallets or door panels with a honeycomb core. We offer it as a building material in trade fair and exhibition construction, for the construction of furniture or playhouses for children, as a light and uncomplicated backdrop material for stage construction in film, theatre or television, as a laminatable carrier board for drawing up plans, photos, posters and and and...

Processing of cardboard honeycomb panels

The various cardboard honeycomb panels can be easily cut with a circular saw, jigsaw or fretsaw. If you don't want to saw the panels yourself, our cutting service will cut them to size for you (in the Berlin shop or online on request). The paper-laminated copies can also be cut very well with the cutter: pull the blade flat through the material freehand or on the ruler.

Folding: Folding is easier with paper- and carton-laminated boards. Paper-laminated sheets are weakened on one side with the folding bone and bent over one edge. The result is a round corner on the outside, the cover paper is creased on the inside. The carton-laminated material can only be folded after removing a top layer strip on the inside of the crease.

Embossing: Recesses are made by cutting the plate on one side to the desired depth of the "embossing" and then pressing it in with a piece of wood and a hammer. However, this only works for small areas or gradually, as the plate is extremely pressure-resistant as described above.

The cardboard honeycomb board can be perforated with a drill or a graver. If paper-laminated boards are to be hung, it is advisable to place a pipe section or rolled cardboard boxes in the hole.

Connecting: The carton-laminated boards can be glued flat with spray adhesiveX-Film DX adhesive foils or Tesa all-purpose adhesive (Technicoll). Bonded corner joints should not be blunt, as the "hollow" plate offers hardly any bonding surface. These joints are more successful when folded and glued flat.

Butt joints can be made as follows: leave one pin at the "impacting" plate and sink it into a slot (cut through or embossed only) in the other plate. If necessary, secure with a pin.

Cardboard laminated panels can also be joined with a screw and nut. A washer as large as possible should be used. A butt joint is obtained by means of a screwed cardboard angle.

Edge protection: PVC U-profile or kraft paper wet adhesive tape can be used to protect the edges. Hard paper tubes are also suitable as connecting or finishing elements. Suitable wooden strips can be glued into the edges of the carton-laminated boards. To do this, remove the honeycomb material in the edge area with the cutter, coat the inside of the cover layers and wooden strip with adhesive (e.g. Pattex) and carefully wrap the strip between the cover layers after the adhesive has dried.

Laminating: The boards are covered with double-sided X-film, spray adhesiveTesa All-purpose adhesive (Technicoll) or paste. If the paper-laminated cardboard honeycomb is glued, the honeycomb structure remains visible at least when thin materials are applied, whereas the cardboard-laminated board is smooth. Counter lamination of the boards is recommended if absolute flatness of the board is important.
