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.[14] 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.[15] 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.[16] 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.[17]
