Tables 3 and 4 show the obtained results. Comparative Example 4
- a transparent vapor-deposited polyethylene terephthalate film was formed on the colored coating layer of the laminated structure obtained in Reference Example 5 using a urethane-based adhesive containing no colorant.
- Stretched nylon film, unstretched poly A propylene film was sequentially laminated by dry lamination to produce a packaging material.
- the substrate is irradiated with light having a predetermined wavelength of 600 nm, 700 nm, 800 nm, and 900 nm from the side on which the white coating layer is not formed, and the transmittance is purple. Inspection was performed using an external visible spectrophotometer V-570 (manufactured by JASCO Corporation).
- a sample of the obtained packaging material is placed on a colored mount in which black, indigo, purple, red, and yellow are arranged in this order such that the side of the base material on which the white coating layer is not formed comes to the front side, and is visually observed.
- the concealability was determined based on whether or not the color of the colored mount was visible. The criteria were as follows.
- ⁇ The color of the colored mount is slightly visible.
- A The color of the colored backing is hardly recognized.
- the obtained packaging material is overlaid so that the unstretched polypropylene film is on the inside, and the periphery of the three sides is heat-sealed (condition: 220 ° C, 2 seconds) to form a bag with a content of about 5 O ml.
- the body was made.
- the bag in which the pseudo food was sealed was subjected to a retort treatment (120 ° C, 30 minutes). 1 f
- Laminating adhesive strength (between substrate PET and vapor deposition PET) of the packaging material before and after the retort treatment was measured using a STROGRAPH MI (manufactured by Toyo Seiki Seisaku-sho, Ltd.).
- the measurement was performed using a STROGRAPH MI (manufactured by Toyo Seiki Seisaku-sho, Ltd.).

- the packaging material according to the present invention As shown in Tables 1 to 4, in the examples of the packaging material according to the present invention, the number of times of printing in the formation of the white coating film layer is small, and even if it is relatively thin, sufficient light shielding properties are exhibited. It is. In particular, depending on the formation of the ink coating layer, it has a light transmittance of less than 1% for each wavelength and excellent concealing properties, which can only be obtained by printing four or more times. It can be seen that the packaging material can be achieved by combining the printing of the white ink twice or three times with the colored adhesive layer, and the manufacturing cost and the number of manufacturing steps can be reduced. In terms of laminating adhesive strength and heat sealing strength, characteristics comparable to those obtained by using an uncolored adhesive were obtained.
