Packaging container and method of manufacturing the same

Abstract

An object is to provide a packaging container which can be easily recycled after being thrown away, which allows food to be heated by dielectric heating, and which has an excellent thermal insulating performance. Another object is to provide a method for manufacturing the packaging container. The packaging container includes a sleeve (12) having upper and lower ends folded inward, a film (16) which covers the sleeve (12), an inner container (11) formed inside the sleeve (12), and a lid for sealing the inner container (11). The film (16) and the inner container (11) are fused and joined integrally at folded portions of the upper and lower ends of the sleeve (12). Since it becomes unnecessary to provide a thermally activatable adhesive or the like between the sleeve (12) and the inner container (11), or to apply a thermally activatable adhesive or the like onto the inner surface of the sleeve (12), storage and handling of the sleeve (12) become easier.
