A method for evenly dyeing yarn cheeses comprising: enveloping the cheeses, which have a generally cylindrical outer configuration, e.g. a cylindrical, truncated conical, pineapple cone form or the like, in a perforated heat-shrinkable film of a synthetic resin; applying heat to the film to shrink and adapt it to the outer configuration of the cheeses, thus wrapping up the cheeses in the film; charging the wrapped cheeses onto spindles in a dyeing machine; and flowing a dye liquor through the wrapped cheeses from inside the spindles to the outer yarn layer sides of the cheeses, and vice versa, alternatingly, thereby evenly dyeing the cheese. Preferably, the film is fashioned into a generally cylindrical body having a marginal extension projecting longitudinally through a joint line thereof, wherein the body is hot-melt sealed to form the joint line. The film can be readily removed from the cheeses by tearing along the joint line, when the extension is pulled.
