I've been using this one for a year and works ok with corrugated cardboard. It just might heat up if you do too much.

I've been using this Fellowes 10-sheet micro-cut shredder for the last two years and it has been a real champ: https://www.amazon.com/gp/product/B010E9M3KG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1&fpw=alm

Amazon says it's currently unavailable so they may have some new model or something. I think when I bought it it was about $80 but I could be wrong. But at the time I bought it I specifically wanted something that was rated for several sheets because when I run paper grocery bags though, I just rip them down the middle and fixed them in, which works really well from an efficiency standpoint (as opposed to having to cut the whole thing up). If you think about it, when feeding them in this way when the bottom of the bag goes through the shredder it is having to process up to five sheets thick of grocery bag (two sides of the bag plus two sides of the lower bag plus the bottom).

Additionally, the micro cut option seems to be the perfect size. I put kitchen scraps in a 5 gallon bucket with a Gamma Seal lid. When I do a run out to the worm bin I often mix the kitchen scraps with the shredded paper and then put it into the overall bin. I've had really good results with this as it generally prevents big pockets of kitchen scraps and keeping things airy and all that. The gamma seal lid on a 5 or 7 gallon bucket has been really great because my scraps sit outside my kitchen (I have a side door in the kitchen) and the lid is really quick to remove but also tight enough to keep fruit flies and things out. It's the best solution I've found over the years in terms of balancing how much effort I need to put in as well as keeping rats out of the 'staging' area.
