it's because my $zip = Archive::Zip->new(); AND writeToFileNamed are both in the loop .. so you're not appending to the same zip object -- you're creating, adding one file, writing out to disk, and then $zip is destroyed before the next iteration. Move my $zip = Archive::Zip->new(); to before the forloop, and the write to after. 
my $zip = Archive::Zip->new();
foreach $case (@items) {
  ...
  my $member = $zip->addDirectory( 'dirname/' );
  $member->desiredCompressionMethod();
  $member = $zip->addFile( "$file_to_zip", "$file_name" );            
+   
}
die 'write error' unless $zip->writeToFileNamed( $zip_file_name ) == A
+Z_OK;

btw, are you doing use strict; and use warnings; somewhere in your code?
