CORRUGATED CARDBOARD

      We have been using corrugated cardboard designed for the purpose of transporting sensitive products for about 100 years. Corrugated cardboard have been used in different structures and sectors, but the patent thereof has been obtained in about the 1850’s. This patent was obtained in 1856 in the UK, but it was designed in the form we use now by Albert Jones in New York.

The first machine for producing large quantities of corrugated board was built by G. Smyth in 1874, and in the same year Oliver Long improved upon Jones’s design by inventing corrugated board with liner sheets on both sides. This was the forerunner of the corrugated cardboard we know today.

PRODUCTION OF CORRUGATED CARDBOARD

        Corrugated cardboard formed by means of a cardboard material corrugated by grooves between two straight cardboard materials provide a high level of protection since it absorbs impacts due to its special structure. This cardboard manufactured from paper sheets of 0.25 mm in thickness is mostly used for the production of boxes. Corrugated cardboard and cardboard box are two different products that are often confused with each other, but although the paper material used for the production of corrugated cardboard looks like cardboard material, it is not cardboard.

 

Such machines with a complex mechanism and high level of sensitivity are used in the production of corrugated cardboard to avoid any possible deformation. The manufacturing process that starts with the paper made of copper and cellulose fibers used in the production of cardboard being moistened with vapor pressure and, continues the paper being dried at a high temperature to shape it and maintain the shape. Corrugated cardboard manufactured with a high level of energy consumption is one of the packaging materials delivering the highest performance.

MANUFACTURING PROCESSES THAT MAKE A DIFFERENCE

     Different characteristics may be needed in the production of corrugated cardboard depending on the need for packaging. Additional characteristics such as water impermeability, coloring, additional unit applications and, reinforcement for larger scale of transportation business are added to the cardboard using different processes. A proper course of these processes called Coating, Painting, Tear Tape and Reinforcing Tape affects the quality and protection level of the product achieved as a result of the manufacturing. During the process called Coating, additional applications are made to ensure that the cardboard manufactured are resistant to water and, a special type of glue should be used accordingly. It is possible to deliver a different floor color by means of a process called surface painting, which is applied during the manufacturing, but this system is not commonly used in our country. And the process called Tear Tape makes the packaging used for the purposes of handling and transportation suitable for exhibition. Tear tapes must be attached to the boxes that are to be used for these purposes during the manufacturing process. Reinforcing Tape are used in the production of corrugated cardboard designed for the purposes of a large scale of transportation. These tapes are applied in frequent intervals during the manufacturing of these types of boxes also known as bulk bin capable of transporting a large weight of loads. This process delivers a high level of reinforcement to the cardboard and, thus results in a significantly lower level of deformation.
