によってシール（密封）状態が得られる。The article to be packaged is wrapped with this packaging film 1 and folded along the side surfaces 2, 3 and 4, and the folded portions are used as adhesive portions. That is, by applying heat to the folded portion, the film in this portion is melted and adhered, whereby a sealed state is obtained.
【００１４】本例においては、上記側面２，３，４の各
面の接着部のうち、側面４における接着部５に開封手段
を設けてある。この開封手段を詳細に説明すると、先ず
接着部５の一部には、開封のきっかけとなる凹状の切り
込み部６が設けられている。In the present embodiment, the unsealing means is provided at the adhesive portion 5 on the side surface 4 among the adhesive portions on the respective side surfaces 2, 3 and 4. The opening means will be described in detail. First, a part of the adhesive portion 5 is provided with a concave cut portion 6 that serves as a trigger for opening.

刷を施す工程において同時に行なわれる。In this example, printing is used as a means for partially changing the adhesive strength of the adhesive portion 5. That is, in this example, since the PP film is heated and adhered, if printing is performed on this adhered surface (when ink is placed)
It becomes difficult to adhere, and the higher the density of this printing, the weaker the adhesive strength. Therefore, by utilizing this, in this example, 100% solid printing is performed on the adhesive surface of the portion a, and a mesh having a gradation of 60% → 0% from the side near the cut portion 6 is applied to the adhesive surface of the portion b. Dot printing is done respectively,
No printing is performed on the adhesive surface of the portion c. It should be noted that the printing of the adhesive portion 5 is performed at the same time as the design printing on the transparent film.
【００１８】上記の如き印刷を施したことにより、この
部分に熱を加えるとａの部分は殆ど接着されず、ｂの部

側の部分には何らの印刷も施していない。このため熱を
加えると、切り込み部６のすぐ両側は接着強度が弱く、
切り込み部６から離れるに従って徐々に接着強度が強く
なるように接着されることになる。Also in this example, the adhesive strength of the adhesive portion 5 is partially changed. That is, in this example, the portions indicated by d on both the left and right sides of the cut portion 6 (range of about 10 to 20 mm)
In the same manner as in the portion b of the first embodiment, halftone dot printing with gradations of 60% → 0% is symmetrically applied to the adhesive surface of the above. No printing is done on the part. Therefore, when heat is applied, the adhesive strength is weak on both sides of the cut portion 6,
Bonding is performed so that the adhesive strength gradually increases as the distance from the cut portion 6 increases.
【００２３】このように本例では切り込み部６の左右両

開封することができる）。As described above, in this example, since the adhesive strength on the left and right sides of the cut portion 6 is weak, it can be easily opened from here (in this example, the portions on both sides of the cut portion 6 are adhered although they are slight. Therefore, unlike the first embodiment, it does not curl up due to heating, but it can be easily peeled off by rubbing it once with a nail or the like, and the opening can be easily used as a trigger.
【００２４】そして本例では切り込み部６が中央にあ
