PROBLEM TO BE SOLVED: To provide a packaging apparatus and its manufacturing method wherein the packaging apparatus can be easily unsealed to remove from a packaged object and the entire packaging apparatus can be disposed of as a single body. SOLUTION: A cylinder 12 formed with a joint strip 14 by overlap-joining a surface of one of side rims of a thermoplastic film sheet and a rear face of the other with each other in a strip is equipped with guide-to-unseal means 15, 17 from one of opening rims to the other opening rim with a predetermined width left in the vicinity of both sides of the joint strip 14 in parallel to it. The cylinder 12 is put over a surface of a container and heat-shrunk, constituting the packaging apparatus 10 as an end face coat 12a wherein at least a part of an annular portion with the predetermined width of the cylinder 12 covers at least a periphery of one of the end faces of the container and a peripheral side face coat 12b wherein a remaining part of the cylinder covers a peripheral side face and at least a part of the other end face of the container. |
