Single use packaging has done wonders for maintaining sterile technique. It's also done wonders for the plastic packaging industry's bottom line. Funny how Hospitals used to have no trouble maintaining sterile technique when they didn't have everything individually wrapped to within an inch of its life? Of course, they used to have to pay the technicians who sterilised everything so there's a point they can make, but they also didn't have to buy everything brand new every time they want to use it either.
