However, white heat-shrinkable films are required from the viewpoint of diversification of designs. As a method of whitening a heat-shrinkable film, a method of containing an inorganic white pigment such as titanium oxide and a coating method using a white ink are proposed (for example, Patent Document 1 and 2).[Patent Document 1] Japanese Unexamined Patent Application, First Publication No. 2004-155482[Patent Document 2] Japanese Unexamined Patent Application, First Publication No. 2005-212226However, it is difficult to uniformly disperse an inorganic white pigment in a resin film. As a result, problems such as classification and an increase in specific gravity of the film occur. In addition, the coating method using a white ink is not easily performed.Moreover, when a label looks unattractive, a product having the label mounted thereon also gives a bad impression.
