Abstract
An insertion plunger for inserting at least one wrap-around label and at least one bottom label into an injection mold for producing a plastic container has an outer plunger and an inner plunger that is movable relative to the outer plunger. In a method for insertion of a wrap-around label and a bottom label into an injection mold, the labels are inserted by an insertion plunger in that the wrap-around label and the bottom label are inserted in a single stroke performed by the insertion plunger into the injection mold.
