Not exactly sure what you're trying to do, but my suggestion is:

sedcmd="sed -i "
$sedcmd s/$orig_pkg/$package_name/g $f

You must set variables orig_pkg package_name and f in your shell first.

If you're replacing variable names in a file, try:

$sedcmd s/\$orig_pkg/\$package_name/g $f

Still f must be set to the file name you're working on.
