いうのが昨今の状況である。2. Description of the Related Art Conventionally, paper cups and plastic cups have been used as containers for instant noodles. In this case, the lid material is a thin paper / aluminum foil / polyethylene composition or the like in order to prevent the instant noodles, which are the contents, from being discolored or oxidized by the light of a fluorescent lamp when displayed in a store. Lids made of aluminum foil have been used. The use of aluminum foil is much better in terms of protecting the contents such as light shielding, gas barrier, and water vapor barrier (moisture permeability), but it is seen from the environmental aspect such as streamlining of packaging and disposal of waste. However, the current situation is that using aluminum foil is not the best method.

い。In order to evaluate the light transmittance of four types of lid materials, the fading properties of the contents, and the tearing of the lid material at the time of opening, they were checked and measured in accordance with the following test methods. . Table 1 shows the results. Light transmittance of the lid material: A 330 type spectrophotometer (manufactured by Hitachi, Ltd.) was used to measure the transmittance in the ultraviolet region of 878 to 350 nm, and the scanning speed was 100 mm / min. Fading property of contents: A bead-expanded polystyrene container (hereinafter referred to as EPS) having an internal capacity of 50 g filled with leeks, instant noodles, and dried shrimp is sealed with the above four types of lid materials. Each sealed container is left under a 600 lux fluorescent lamp for 1 week. Then, the container is opened and the contents of the container are visually observed for the degree of fading. ○ ‥‥ No fading. ×: There is fading. Rupture of the lid material when opening ... The sealing pressure of the EPS and each lid material is changed with a cup sealer, and the sealing pressure is 2 kg / c.
Sealing is performed under conditions of m 2 and sealing time of 0.8 seconds, and then the lid material is opened and the opened state is observed. ○ ・ ・ ・ The lid does not tear and peels off from the EPS cleanly. × ・ ・ ・ The lid is torn and cannot be removed from the EPS cleanly.

わかる（比較例１）。Considering from Table 1, the lid material on which the ultraviolet absorbent coating layer is formed and the acrylic resin layer is formed on the surface on which the ultraviolet absorbent coating layer is not formed has no fading of the contents, It can be seen that the lid material does not break when opened in a wide sealing temperature range (Example 1). On the other hand, a lid material that does not form an ultraviolet absorber coating layer or a lid material that does not form an acrylic resin layer is insufficient as a lid material for instant noodles, because the contents may fade or the lid material may tear when opened. (Comparative Example 1).

る。As described above, according to the present invention, the lid material in which the organic ultraviolet absorber is applied to the thin paper, and the acrylic resin is applied to the surface not coated with the organic ultraviolet absorber is It can be seen that it is suitable as a lid material for instant noodles. It can be seen that the performance is not inferior to the conventional lid material using aluminum foil. Since the aluminum foil is not used, the lid member of the present invention can be preferably used from the viewpoints of rational packaging and easy disposal of waste.
