Abstract

L'invention concerne un adhésif pour sacs en papier contenant essentiellement de l'amidon et un procédé de sa préparation. Pour préparer un adhésif à base d'amidon pour sacs en papier qui peut contenir des charges minérales et des additifs connus, on amène l'amidon sous une forme pratiquement soluble dans l'eau par mélange d'une suspension aqueuse constituée d'amidon ou constituée essentiellement d'amidon, à une température de 120 à 200 degrés C, sous une pression supérieure à la pression atmosphérique, de façon à ce que la viscosité finale de l'adhésif, mesurée à 25 degrés C avec un viscosimètre Brookfield muni d'une tige n degrés 4 à la vitesse de 20 tr/min, soit de 700 à 5 000 mPa.s et mieux de 1000 à 3 000 mPa.s. L'invention s'applique en particulier à des adhésifs pour sacs en papier convenant à l'emploi avec les machines de fabrication rapide de sacs en papier.The invention relates to an adhesive for paper bags essentially containing starch and a process for its preparation. To prepare a starch-based adhesive for paper bags which may contain mineral fillers and known additives, the starch is brought into a substantially water-soluble form by mixing an aqueous suspension of starch or consisting essentially of starch, at a temperature of 120 to 200 degrees C, under a pressure above atmospheric pressure, so that the final viscosity of the adhesive, measured at 25 degrees C with a Brookfield viscometer fitted with a n ° 4 rod at a speed of 20 rpm, i.e. from 700 to 5,000 mPa.s and better still from 1,000 to 3,000 mPa.s. The invention is particularly applicable to adhesives for paper bags suitable for use with high speed paper bag making machines.
