If any of you know someone who works in a factory, you should ask them if they use plastic wrap on their palletized items.
Most food places package items in boxes or cases of some sort, those get stacked on pallets and the entire pallet goes through a wrapper where it is wrapped in industrial (but still food grade) plastic wrap. Very few operators run the rolls completely empty. Instead, when it gets down to about a 1/2 to 1/4 inch of wrap left, they pull it off and add a new roll. The new rolls are about 10 to 14 inches in diameter and ours came in two lengths. The small ones were about the size of the wide stuff you get in the stores and the long one is about two feet long. The long ones are great for wrapping big pieces of meat like entire hind quarters.
At the factory I worked at, these used rolls would be thrown away all the time and some had a good 1/2" of wrap left on the tube. The tubes were about 3" diameter, heavy cardboard so 1/2" on that big tube was a LOT of plastic wrap if using it at home. One roll would last in our kitchen about 3 to 6 months. I'd ask a manager for a material pass for "used shrink wrap rolls" and they'd give me one no problem. I'd bring 10 to 15 of them home at a time. Still have some in the basement but don't work there any more so I'm kinda being frugal with them. While I was working there, I gave away a bunch of them to friends who hunted.
Cool thing was, it is heat shrinkable. Wrap stuff with it and use a hair dryer or heat gun and it shrinks down wicked tight. Basically the same as meat from the store in the styrofoam trays. If you look at most of those from the bottom, you can see it was plastic wrapped and the bottom was heated to stick it all together.
Just thought this was an option to throw out there. I've gone through the same thing with vacuum sealers and blood in the seal or the units not lasting very long and have gone back to just multiple layers of plastic wrap. Heck, I was getting it for free so I wasn't stingy. Going around and around half a dozen times seals stuff where it will last for years. I don't even bother with freezer paper or bags most of the time.
Here in the midwest, there are a lot of factories and even those that don't make food still use a palletizer to stack and wrap the pallets of goods to be shipped out to the stores. Heck, just look in Home Depot or Sam's Club at the pallets on the shelves and you will see what I'm talking about. Practically EVERYTHING gets shrink wrapped onto pallets these days.
By the way, those stores can be a good source of used plastic wrap which just happens to be one of the best things there is for the you-stuff-it type targets...
