What is the undulating cardboard?

corrugated cardboard was patented in England in 1856. It is made of paper and consists of grooved paper between two flat plates. This design results in a stronger and more durable product that is widely used for transport.

This product is also called pleated paper and was originally used as a liner for hats designed to protect high hats. December 20, 1871, a patent was released on its use Albert Jones from New York. It is commonly used to protect bottles and glass chimneys.

Oliver Long made a significant change in design and added insert leaves to both sides, creating a corrugated cardboard design that is still used to this day. The machine for the production of this material was built in 1874 G. Smyth. The combination of these two changes has significantly increased the demand and use of this new product.

corrugated cardboard has become a very important product when Robert Gair used it to create a corurugated box in 1890. This box was capableTo replace wooden boxes and boxes at a lower price without losing the ability to protect the product during transport. This box design made it possible to send products without damage, which significantly increased the size of the export market.

6 To create undulating cardboard, the paper is subjected to high -pressure steam that softens the fibers. The fibers are bent to create the desired flute thickness between the cardboard leaves.

Furthermore, pressure on the upper and lower part of the cardboard is to increase the power of the material. The flat plates of the insert are brushed on one side with glue and then the corrugated cardboard is inserted between two layers of the flat insert. This material can be made in different colors, but most often produced in brown, white or spotted white.

Flute thickness can be modified to create different degrees of strength in undulating cardboard. In the US there is 5 standard thickness, marked with letters and to F. The letter shows when wouldl invented, not relative size.

There are different types of construction within the undulating cardboard depending on the requirements for the final product. Suppliers can create one wall, a double wall, a specific flute size, a rupture force, the power of crushing of the edges and more. Special surface treatment, coatings and covers can also be provided.
