According to one commenter there are some semi-valid reasons –
The companies that provide these services claim a lot, but it is definitely going to provide the protection from the following things:
Tampering (or at least make it clearly evident)
Weather (rain, snow, etc)
The companies go on to suggest that you can also prevent scratches, wear and tear, and other such things. I find it hard to believe a thin layer of plastic could do that, but it probably does provide some degree of protection from those too.
The most convincing however, is the protection from Weather. The tarmac where the plane is loaded isn't protected from these things. If I have fabric luggage, I can use these wrapping services to prevent rain, mud, or frozen winter shit from getting into or on my luggage. Possibly damaging it permanently. – http://travel.stackexchange.com/a/3233

I've yet to find something missing, but I do find that they don't always close the bag well, or make sure things are inside the way I left them. I hate that.
I've seen this, haven't used it, people do it for tamper proofing.
They also said that if it has to be undone if they find something in the X-ray machine and have to open the bag, they will re do it for free.
