Is that why the boxes all the Made in China stuff comes in seems so thin and weak? Do they only use #7 boxesAnd they will be turned into new boxes.
Corrugated board is one of the most recycled materials. More than aluminum cans, for sure.
You can recycle a box about 7 times before the cellulose fibers get too short to make it over the fourdrinier screen at the paper mill. That's ok, those short fibers will be dried and turned into energy at the boiler.
Wonderfully efficient industry.
