Beschreibung
Zusammenfassung:	The present invention relates to a polyether having a urethane group density of from 2 to 10 urethane groups per mol of polyether, a polyurethane (PU) adhesive that comprises the polyether and at least one NCO-terminated compound, and to the use of the polyurethane adhesive for producing packaging, in particular food packaging. L'invention concerne un polyéther ayant une densité de groupe uréthane de 2 à 10 groupes uréthane par mole de polyéther, un adhésif polyuréthane (PU) qui comprend le polyéther et au moins un composé à terminaison NCO, ainsi que l'utilisation de l'adhésif polyuréthane afin de produire un emballage, en particulier un emballage alimentaire.
