1 and the gripping sheet 2 are torn together, and
If you try to remove the halved package from side to side,
This is because the object 2 is also removed together.
In addition, it is high in the overlapping portion between the edges of the interior films 4 and 5.
When heat is transmitted and the edges are welded together,
Even if the opening with the piece 1c is completely completed at 360 degrees, the interior
The edges of the lumps 4 and 5 and the edge of the exterior film 1 are welded
Is not completely divided into two parts,
Cannot be removed from side to side. As described above, in the present invention, packaging is completed.

It is good to match to film 1. That way, the heat
Insert the knife edge of the sealer 16 into the film and draw
When providing a notch 7 for tearing by fusing
Since the only sheet 2 is a heat-resistant film,
There is no cut in the laver 3. If the heating temperature of the heat sealer is too high,
Or if the heat sealing time is a little too long
Notch 7 is not a linear cut but a large hole
The periphery of the tearing notch 7 is disturbed, and
Heat is applied to the overlap between the edges of the interior films 4 and 5
There is a fear that a seal will be made. Also, on a triangle rice ball M
