PURPOSE:To improve the resistance to cosmetics and obtain the above film at a low cost by a structure wherein protective layers having the resistance to cosmetics are formed on the outer surfaces of base film made of uniaxially stretched polystyrene. CONSTITUTION:As the stock material of base film 2, which is the base material of the shrinkable film 1 concerned, uniaxially stretched polystyrene film is employed. On the outer surfaces or both the sides of the shrinkable film 1, protective layer 3 having the resistance to cosmetics made, for example, of acrylic resin or the like, which is alcohol-soluble resin and has favorable printability and the coating made of which has lower-solubility to alcohol after being printed and dried, are formed. Through the formation of the protective layers 3, even the uniaxially stretched polystyrene film, which has low resistance to cosmetics, is used for cosmetic liquid, resulting in allowing to supply a large quantity of high quality shrinkable film at a low cost. |
