A packaging bag contains a lens-fitted photo film unit in a pillow-type
package. Optically transparent window sections are provided on front top
and bottom portions of the packaging bag. And a belt-like shaped
lightproof section is provided in a center portion of the window section.
The window section is made translucent by printing a half-tone dot
meshing with a white coating, so that the lens-fitted photo film unit is
observable through the window section. The lightproof section is printed
with a lightproof coating and covers the front of the taking lens. Opaque
coating is printed on an opaque section, which is a portion except the
window section and the lightproof section.
