发明名称 Lens-fitted photo film unit and manufacturing method therefor
摘要 A lens-fitted photo film unit has a body section, a front cover and a rear cover, all of which are plastic parts. These plastic parts are made of raw materials restored from used plastic parts. A plastic parts recycling line is constisuted of a pelletizing line and a non-pelletizing line. In the non-pelletizing line, the used plastic parts are crushed for procuring crushed materials. In the pelletizing line, the crushed materials are melted, extruded and molded into the strand-like resin, which is cut into recycled pellets. The crushed materials are used for forming the plastic parts that are not in contact with a photo film. Meanwhile the recycled pellets are used for forming the plastic parts that are in contact with the photo film.
