Aside from just the convenience of carrying multiple items in a box at a time, packing does way more than just that! Making sure that you pack boxes with as much as you can, while maintaining the integrity of the box so you can stack and pack it. It's also important what size boxes you decide to pack items in because you don't want to overload a box and make it too heavy, especially a fragile box because that makes it hard to put on the top doesn't it. As a mover I see all the different types of packing jobs and I love it when I get the opportunity to pack a house because there is truthfully so much thought that goes into it. The labeling is extremely important as well because not only will it be important for unpacking but also your movers need to know so they know how to pack it, and on top of all they if you need to put it somewhere that you'll need to regularly access items, you'll need a system that'll make it easy to find what you need and be on your way and part of that goes with the packing and labeling and the other part goes down to the stacking and organizing portion of the move. How you pack also effects how much you can fit in whatever you're using to get your items from place to place, because a little known secret is that the amount of trips from carrying to fo and from your vehicle to loads from place to place in a truck/trailer. If you have a lot of loose items it'll be more difficult to stack items to maximize space...why do you think that retail stores put everything in a box? It's not just so you have something pretty to bring things home, and even those boxes and all the other things you get from stores originally come in a box because it's more efficient for spack to get more per a load and it cuts down on trips, and the less space for things to move around the less opportunity for things to break. So be sure to take the packing and prepping portion of your move seriously! I have quite a bit of tips on this in the "Man and Dolly Complete Moving Guide".
