The packaging has undergone many changes since its inception. Unlike McDonald's, the company never used the clamshell style box made of Styrofoam, so when the environmental concerns over Styrofoam came to a head in the late-1980s, the company was able to tout its use of paperboard boxes for its sandwiches. To cut back on the amount of paper that the company used, the paperboard box was fully eliminated in 1991 and was replaced with waxed paper. For a short time in 2002, the company used a gold-toned, aluminum foil wrapping for the sandwich as part of the 45th anniversary of the sandwich. The packaging was changed again in 2012 when the company moved to half wrapped sandwich packaged in a paperboard box, marking a return to the paperboard box for its packaging since 1991.
