With the development of market economy, small and medium-sized carton plants in China flowed everywhere. For a long period of time, the relevant departments did not clearly put forward the requirement that adhesive cartons could not be made of adhesive materials by using sodium silicate in the domestic packaging carton. Clearly defined. At present, the market is a popular “cardboard box”, “starch glue”, its performance and price are not ideal, causing confusion to the market, so that users in the choice of glue caused psychological problems, for which many small carton factory due to simple Plans save trouble, so the use of more than 100 years of traditional products sodium silicate do carton bonding material, do not know using sodium silicate as binder there are many drawbacks, experts call for reiteration in the production of cartons should be eliminated sodium ca dope and require the use of Starch binder. Sodium silicate sodium silicate solution, is a strong alkali weak acid salt, was
