Glue for articles of the tobacco industry such as cigarettes, cigarillos, cigars, filter tips, coupling-sleeves, etc., characterized by the fact that at ambient temperature it is in gel form composed mainly of water and gelatine, the gelatine concentration being in the 25-180% range in relation to the water weight, and a minor quantity of plasticizer for the gelatine in aqueous solution, belonging to the food polymers group comprising natural and modified vegetable gums and cellulose ethers, the plasticizer's concentration being within the 0.25-8% range in relation to the weight of the gelatine alone, and being adjusted so that the temperature at which the liquefied gel viscosity remains superior to 50 centipoises and becomes lower than 1000 centipoises is within the 40-70.degree. C. range.
