FIELD: production of the glue composition of labeling assignment.
SUBSTANCE: the invention is pertaining to production of the glue composition of labeling, in particular, to the glue composition designated for sticking of the glue impregnated-paper labels to the glass, plastic, metallic, ceramic and wood surfaces. The invention allows to produce the glue compositions, which are distinguished by the increased frost-resistance: withstanding the multiple freezing and defreezing. The composition is produced by combination of two compounds preliminary heat-treated at the temperature of 80-90°C and their subsequent heat treatment together with the modifying agent - Amylum at 90-95°C, and bring up to pH=7.0-7.5 IN by KOH or NaOH solution. At that the composition 1 contains: dextrin, gum-arabic pretreated at 130°C and under the residual pressure of 05 mmHg, water; the composition 2 contains: colophony, glycerin, borax, water. At that the first composition was thermotreated in presence of several drips of antifoaming liquid. The labels gain positive stability against a shearing within 10 seconds and after 5 minutes can be torn-off only with a break of the paper.
EFFECT: the invention ensures, that the labels gain positive stability against a shearing within 10 seconds and after 5 minutes can be torn-off only with a break of the paper.

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.
