An adhesive composition comprising a two-component system comprising A) at
least one polyester urethane containing at least two isocyanate groups,
which polyester urethane may be obtained by reaction of one or more
polyesters 1 with aliphatic diisocyanates and reaction with one or more
polyesters 2, wherein polyester 1 exhibits a number average molecular
weight Mn in the range from 3,000 to 7,000 g/mol and polyester 2 exhibits
a number average molecular weight Mn in the range from 700 to 2,000 g/mol
and B) one or more branched polyesters with a number average molecular
weight Mn in the range from 1,000 to 3,500 g/mol and optionally one or
more conventional additives; the present invention provides a
polyurethane-based adhesive composition which is suitable for the
production of laminates for sterilizable packaging and exhibits a low
residual content of highly volatile diisocyanates. The adhesive according
to the invention ensures that no or only slight delamination of the film
composites occurs even at elevated temperatures.
