Ah, the blister pack, used to package everything from medications to toys. Perhaps the only thing harder than opening these plastic containers is determining whether or not they are recyclable. Blister packs fall into the catch-all category of rigid plastics, similar to plastic cups, yogurt containers and clamshell packaging. While the recycling market was first limited for rigid plastics due to the challenges of transporting them (they can’t be crushed and baled like plastic bottles), more and more communities are now accepting them in curbside programs.
