Corrugation and Pasting Gum
Pasting and Corrugation Gum powder are used for the manufacture of Corrugated Box Manufacturing. The process and raw material used in the manufacture of Pasting Gum Powder as well as Corrugation Gum are the same as mentioned in Dextrin. The heating process of cold changes from high to moderate to maintain the viscosity.
Pasting Gum powder is available in two different Grades :
Hot Process and Cold Process. In Hot process the powder has to be cooked with recommended ratio in water up to 800 C to prepare the gum. The hot gum are highly recommended to use for the manufacture of corrugated boxes to get the better strength of boxes. Due to high cost of electricity and time consuming the Pasting Gum has been converted from Hot process to cold process.
In Cold Process this Gum is being prepared by adding caustic solution in the mixture of starch with cold water and getting ready in a small period of time. Even the PH value is high in this gum, manufactures preferred the same for fast production and reduction of manufacturing cost. Corrugation Gum Powder is made from raw starch or cooked starch. The Mixer of starch with cold water and caustic solution prepare the gum. Some catalysts are added to increase the strength of boxes.

The ratio is 1:4 (1kg perfect gum powder Cold to 4 liters of Water). Take water in a container and stir it with a stirrer at 900-rpm. While the stirring is in progress, add Smil-o-Cold gradually into the vertex of water formed by stirrer.The Smil-o-cold to water ratio may however, be changed to ensure required viscosity depending on the gsm, quality of paper and single facer or double backer bonding. |
