Abstract

PURPOSE:To produce a packaging material having an excellent light shielding property and throwing property by composing the packaging material of a light shielding layer successively formed with a white ink layer, yellow ink layer and red ink layer on a resin film and a barrier layer formed with an inorg. vapor deposited film on this resin film. CONSTITUTION:This packaging material 1 is formed of the light shielding layer 2, the barrier layer 5 and a heat sealing layer 8 (nonstretched polypropylene resin, etc., and thickness about 10 to 100mum). The light shielding layer 2 is formed by laminating the white ink layer 4a (titanium oxide pigment), the yellow ink layer 4b (disazo yellow pigment) and the red ink layer 4c (watching red pigment) on a resin film 3 (stretched polypropylene resin, etc., and thickness about 5 to 30mum). The coated amts. of the respective ink layers are about 1.5 to 2.0g/m<2> and the light transmittance over the entire part of the ink layers is confined to about <=0.02%. The barrier layer 5 is constituted by forming the inorg. vapor deposited film 7 (SiO2, etc., and thickness about 10 to 100nm) on the resin film 6 (polyester resin, etc., and thickness about 5 to 20mum).
