DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. In the figure, reference numeral 13 denotes an outer body made of a substantially rectangular synthetic resin film having a size large enough to enclose a main body such as an onigiri. The outer body 13 is preferably formed by stretching in the longitudinal width direction, or is made of a material that is easily severable at least in the longitudinal width direction.
A thin film 17 having a longitudinal width is laminated and integrated at a central portion of the outer surface of 3. The outer body 13 at the center of the thin film 17
Is formed with a waveform dividing line 16 extending from the inner surface to the longitudinal width. The thin film 17 is formed to have an appropriate width that can cover the dividing line 16.

Inside the outer body 13, two inner bodies 14, 14 made of a synthetic resin film having respective edges 14 a, 14 a overlapped with each other at the center of the outer body 13 are arranged. Are overlapped with both halves in the lateral direction of the body, and are adhered to the outer periphery of the body by heat sealing or the like.
A bag is formed between 14 and the outer body 13.

Reference numeral 15 denotes a wrapping material, such as laver, which is housed in a bag and formed into an appropriate shape according to the shape of the main body to be packaged.

The thin film 17 is a film obtained by applying or adhering a hot melt adhesive such as edible paste (for example, trade name “Part Coat”) with an appropriate width and laminating the same. By changing the adhesive concentration of such an adhesive,
The strength of the force with which the thin film 17 seals the dividing line 16 can be adjusted as appropriate. In the state shown in FIG.
6 is provided within the width in which the thin film 17 is formed,
The left and right sides of the outer body 13 bordering on the dividing line 16 are thin films 17
Are adhered to each other through the through hole to securely seal the bag body. Therefore, in this state, the dividing line 16 does not open to the left and right, so that the moisture-proof effect of the bag does not decrease, and no foreign matter enters the bag.

The dividing line 16 is a tear line that divides the outer body 13. By forming this in a waveform, the tearing force at the time of opening the packaging material 11 is dispersed at each vertex of the waveform, so that the straight line is divided. It can be more easily torn than when it is broken. Of course, it is not limited to this form,
Depending on the sealing force of the thin film 17, an appropriate mode such as a straight or curved line, a strip-shaped perforation, or the like can be used.

In the method of manufacturing a packaging material having the above-described structure, a thin film is first formed on the center of the outer body when the outer surface of the outer body film is printed on a manufacturing line, and the thin film is formed in the next step. A corrugated tear line is made on the inner surface of the outer body film corresponding to the portion. Then, after placing the wrapped object at a predetermined position on the outer body film while flowing the outer body film and the inner body film in parallel, the inner body film is overlaid thereon, and the outer body film and the inner body film are It can be manufactured by heat-sealing a predetermined position in a state in which the wound material is sandwiched between them, and simultaneously cutting into a predetermined shape.

After the dividing line is formed on the outer film, a thin film may be formed integrally with the outer film, or a thin film may be formed on the inner surface and divided on the outer surface of the outer film. A disconnection may be formed.

Next, a method of using the packaging material 11 having the above configuration will be described. First, as shown in FIGS.
