Blister packs for medication are a plastic/aluminum composite that can't be recycled. A necessary evil, I suppose.
But they can still be used for something! I've been bandaging an injury on my hound, and noticed the scissors were getting all gummed up with tape adhesive and didn't cut well. So, I made a few cuts into the empty blister packs for his meds and voila, they cut better. Looking at the blades, I could see the goop had been moved away from the zone where the cutting surfaces meet.
I'm pretty sure that's where the myth of "cutting aluminum with scissors to sharpen them" comes from. Aluminum doesn't abrade steel, therefore no actual sharpening occurs. But it's very effective for grabbing adhesive and other goo out of the working zone, meaning the scissor sections aren't being pushed apart by foreign material. And the scissors seem to cut properly again.
