UPS and Purolator are generally kinder on baggage (I don't know about Fedex) because they're too cheap to buy all that wicked machinery and use static chutes when moving bags from one conveyor to another. However these chutes are poorly designed and the bag comes off the end of the conveyor fairly fast and hits the wall of the chute before dropping down. I had a design for a 'kinder - gentler' chute at one time but no one was interested because it would have required actually making a trial one and adjusting it for best performance. It would have also been a lot cheaper to make but as the company I worked for had priced their bid on the more expensive 'standard' chute, they weren't interested.
