本考案は紙とフイルムとの積層材からなる二重
角底袋の改良に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a double square bottom bag made of a laminated material of paper and film.
プラスチツクフイルムと紙との積層材から構成
する二重角底袋の製造に当たり、接着剤として、
サイドシール、底シールともにエマルジヨン糊を
用いる場合と、サイドシールはホツトメルト剤、
底シールはエマルジヨン糊を用いる場合とがあ

When manufacturing double square bottom bags made of a laminated material of plastic film and paper, as an adhesive,
In some cases, emulsion glue is used for both the side and bottom seals, and in other cases, hot melt adhesive is used for the side seals.
The bottom seal may be made of emulsion glue, and current technology relies on one of these.
〔考案が解決しようとする課題〕
しかし、かかる構成ではサイドシールに問題が
あつた。すなわち、サイドシール部では、紙とフ
イルムとの積層材の両側縁部を重ね合わせてシー
ルするため、その重ね合わせ部では、一方の側縁
部の紙と他方の側縁部のフイルムとが向い合うこ
ととなり、紙とフイルムとの接着が必要となる
が、紙とフイルムとを良好に接着しうるエマルジ
ヨン糊はあまり見られない。しかも、エマルジヨ
ン糊は、水分が蒸発し、樹脂が造膜硬化してはじ
めて接着力が生じるため、十分な初期接着力を得

難しい。特にフイルムに対してはフイルムが吸水
性を有していないため、一層エマルジヨン糊中の
水分の蒸発が遅く接着に時間がかかつていた。[Problem to be solved by the invention] However, with this configuration, there was a problem with the side seal. In other words, in the side seal section, both edges of the laminated material of paper and film are overlapped and sealed, so in the overlapping section, the paper on one side edge and the film on the other side are facing each other. Therefore, it is necessary to bond the paper and film, but emulsion glue that can bond paper and film well is not often found. Moreover, emulsion glue produces adhesive strength only after the water evaporates and the resin forms a film and hardens, so it takes a considerable amount of time to obtain sufficient initial adhesive strength, making it difficult to speed up bag-making operations. In particular, since the film does not have water absorbency, the water in the emulsion paste evaporates more slowly and takes more time to bond.
一方ホツトメルト剤は、溶融したホツトメルト
を塗布−圧着−冷却することにより直ちに接着す
るので、ごく短時間で接着が完了し、製袋の高速
化が容易である。反面ホツトメルト剤の接着力に
は温度依存性があり、高温（40℃以上）及び低温
（５℃以下）になると、接着力が低下する。この
ため、ホツトメルトを使用した包装袋は、夏、冬
は輸送途上で破袋を生じる恐れがある。 On the other hand, hot-melt agents bond immediately by applying, pressing, and cooling molten hot-melt, so that bonding is completed in a very short time, making it easy to speed up bag manufacturing. On the other hand, the adhesive strength of hot melt agents is temperature dependent, and the adhesive strength decreases at high temperatures (above 40°C) and low temperatures (below 5°C). For this reason, packaging bags using hot melt may break during transportation in summer and winter.

As shown in the drawing, the double square bottom bag of the present invention has a double square bottom bag 1 made of a laminated material of paper 2 and film 3.
, it has a side seal part 5 in which both side edges of the laminate are overlapped and sealed together, and among the side edges constituting this side seal part 5, the side edge of the laminate that contacts the paper ( At the side edge located on the lower side in Figure 2), extend the paper longer than the film so that the paper faces each other, and at the other side edge (the side edge located on the upper side in Figure 2). ), the film is stretched longer than the paper so that the films face each other, and the adhesive part 51 is made of emulsion glue in the part where the paper faces each other, and the adhesive part 51 is made with a hot melt agent in the part where the two films face each other. It is characterized in that a portion 52 is provided respectively.

Because hot melt agents immediately develop adhesive strength,
Forming the adhesive portion 52 using a hot-melt agent makes it possible to speed up the bag-making operation. Furthermore, this adhesive part 52
Since only the film 3 is attached to one of the side edges to be bonded, cooling can be carried out quickly, making it possible to achieve even higher speeds. In addition, by making the paper face each other and forming an adhesive part 51 using emulsion glue in that part, it is possible to achieve strong adhesion, maintain high temperature and low temperature resistance properties of the bag after bag making, and improve packaging. Demonstrate sufficient performance as a bag.
