PROBLEM TO BE SOLVED: To prevent a content packaged object from coming out by bringing a heat-sealing layer of a cushioning synthetic resin sheet which has been heated to be adhesive into contact with an adhered of an opposite cushioning synthetic resin sheet to package the object between both cushioning synthetic resin sheets. SOLUTION: A cushioning synthetic resin sheet S1 fed from one of sheet supply beams on which cushioning synthetic resin sheets S1 , S2 of an air cellular composition are rolled is heated on an adherents where it mates with the other sheet S2 at a predetermined temperature thereby forming an adhesive heat- sealing layer (h). Both cushioning synthetic resin sheets S1 , S2 are made to pass through a sheet discharge port 13a on a lower part 13 of a guide plate with an object C to be packaged interposed between their adherends, and upper and lower parts of the sheets S1 , S2 interposing the object C which have been fed out with both side ends heat-sealed by a sheet side end pressing roller 11 are pressurized for heat-sealing. |
