Packaging device for home delivery service

Abstract

[Object] To reduce the trouble of packing an article the repair of which a customer is going to request. [Solution Means] A mat 1 , an outer layer sheet 2 , and cushioning bodies 4 are combined. The mat 1 is an airtight square-shaped sheet, and is sealed airtightly and laminated on and integrated with the outer layer sheet 2 to form a packing region Wa. The packing region Wa sandwiches an articles M and is folded in two, and a flap 5 of the outer layer sheet 2 formed on an extension portion of the packing region serves as an extension portion Wc that closes a gap of the folded portion of the mat 1 . When the air in the mat 1 is evacuated and the capacity of the bag body is reduced, the cushioning bodies 4 fit the shape of the article packed in the mat 1 and increase the filling density, and are brought into close contact with the surface of the article M.
