I think you've got yourself a bargain bagful of Danish (not German) yarn.
I don't speak any of the Scandinavian languages, but from experience I am guessing that:
the "U" in ULD stands for "Ull," which is wool;
Polyamide is a form of nylon;
"Garn" is yarn;
And "jumper" equals sweater though "jumpergarn" might refer to knitting yarn in general.
From their Web site, Strompe would appear to be a Danish manufacturer of fiber products.

If there's any gauge or care information on the label it's probably shown in international symbols and can be easily translated.
