Starch and Corrugated Cardboard Manufacturing - Its History and Bonding with Starch Adhesive?-

Abstract

Corrugated cardboard was developed about 100 years ago. Jordan V. Bauers of the Stain Hall Company, developed a starch adhesive of high concentration (starch solids 18-25%) and low vis-cosity (150-250 cps) in 1940, and since then high-speed mass-production of corrugated cardboard has been possible. The largest corrugater in the world currently is 350 m/min, and 3000 mm in the paper width. As for the starch adhesive for corrugated cardboard manufacturing, three kinds [Stain Hall System (two-tank system, one-tank system), Premix System (one-tank system), and No Carrier System (one-tank system)] are used. In this text, the principle of bonding corrugated cardboard and an outline of the corrugated cardboard manufacturing method are first described, and the manufac-turing methods, features, etc. of each adhesive are explained afterwards. In addition, problems, etc. which occur when corrugated cardboard is manufactured using these adhesives are described, and actual countermeasure are explained.
