provides substantially complete sunlight shielding characteristic and the sunlight shielding characteristic is lowered at a given rate to its minimum sunlight shielding characteristics application_number US 19123394 A description referring now to the drawings particularly to fig1 the preferred embodiment of a growing fruit protective paper bag has a two bag construction including an outer bag 1 and an inner bag 2 the outer bag 1 is provided a predetermined and constant sunlight shielding characteristic ratio of sunlight which is passed so as to pass the sunlight in a controlled amount and or intensity on the other hand the inner bag 2 is colored to initially provide a substantially complete sunlight shielding characteristic a color provided in the inner bag 2 has the property of fading as a result of irradiation by the sunlight through the outer bag 1 to reduce the light permeability the final light permeability of inner bag 2 after completely fading is selected so that a limited amount or intensity of sunlight is irradiated on the surface skin of fruit and a desired degree of total sunlight shielding is attained in cooperation with the sunlight shielding characteristic of the outer bag 1 therefore when it is time to remove the protective bag the desired final light permeability is established as seen in fig1 the outer bag 1 has an open top end 1a to accommodate the inner bag 2 similarly the inner bag 2 has an open top end 2a both of the outer and inner bags 1 and 2 are formed with slits 1b and 2b for permitting a stem 3a of the fruit 3 to extend therethrough.
