Yes, you may use a baler for compacting light metal waste like food cans and aluminium cans.
You need a baler with a relatively high press force to compact empty aluminium cans. It is important that the material is well compacted from the very first press cycle. Our X-series balers, which have cross cylinders with long cylinder strokes, are very suitable for this purpose.
We recommend that you put a layer of cardboard at the bottom and on top of the bale to keep it stable. Sometimes you might also benefit from wrapping the finished bale with plastic film.
