SUBSTANCE: composition contains carrier starch and secondary starch. The carrier starch contains (in terms of dry mass), less than 50% pre- gelatinised starch and has higher sensitivity to alkali than the secondary starch. The secondary starch is selected from a group comprising maize starch, potato starch, wheat starch and a mixture of two or more of the said types of starch. The carrier starch is selected from a group comprising wheat starch, potato starch, cassava starch, barley starch and a mixture of two or more of the said types of starch. The composition contains (in terms of dry mass) 0.5-60% carrier starch, 40-99.5% secondary starch and 1-8% alkali. The composition also contains (in terms of dry mass) 0.1-3.5% boron compound. An adhesive is obtained by adding the composition to water and stirring while adding a sufficient amount of alkali. The adhesive is used to make corrugated cardboard and multilayer materials. The advantage of the adhesive composition lies in that it can be easily prepared with low expenses on time and equipment.

EFFECT: use of the adhesive improves quality of cardboard, reduces adhesive consumption and increases rate of production.
