〔産業上の利用分野〕
本発明は主として米袋のような強靭なプラスチック製の
袋を得るための包装材の製造方法に関し。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention mainly relates to a method of manufacturing a packaging material for obtaining strong plastic bags such as rice bags.
包装材の基材フィルムへの印刷の入れ方に特徴を有する
ものである。It is characterized by the way the printing is applied to the base film of the packaging material.
包装フィルムの代表例としてポリエチレンフィルムが公

あって完全密閉ができ、引裂強さや（Ｇｊ撃強さが大き
く柔軟で強靭、しかも無毒・無臭であるなど包装フィル
ムとしての必要な性質の殆ど全てを備えている。Polyethylene film is known as a typical example of packaging film. This is the cheapest of all plastic films (
It is easily available, can be easily thermally bonded (heat-sealed), can be completely sealed, has high tear strength (Gj impact strength), is flexible, strong, and is non-toxic and odorless, all of which are necessary for packaging films. It has almost all the characteristics.
しかし、ポリエチレンフィルムの最大の欠点は材質的に
高級印刷が困難な点にある。つまり、材質的に印刷適正
に欠ける。However, the biggest drawback of polyethylene film is that it is difficult to perform high-grade printing due to the material. In other words, the material is not suitable for printing.
一方、ポリエステルフィルムはプラスチックフィルムの
巾でも引張強さが大きく、従ってフィルム厚みを極めて
薄くてき２ とくに美しい多色印刷が可佳であることが
知られている。On the other hand, it is known that polyester film has a high tensile strength even with the width of the plastic film, and therefore the film thickness can be made extremely thin, and particularly beautiful multicolor printing is possible.

袋をつくれない。[The invention solved it! However, even if a laminated polyester film (laminated with a polyester film already printed on a polyethylene film) is used as a packaging material, it is not easy to make bags from the laminated film. This is because the packaging material is in an unfolded state, so first we fold it up and then heat seal the periphery of the opening 171. 1 must be joined. In other words, unless at least two sides are thermally bonded, it is not possible to create a bag that is open only on the top.

が施されていない。基材フィルムが印刷適性を有するか
否かはさておき。On the other hand, as a simple packaging material, a base film is formed into a long cylindrical shape, and after filling the base film, the edges of both openings are heat-sealed. There is. However, the surface of the base film in that case is not printed. Regardless of whether the base film has printability or not.
筒状の基材フィルムの表面に全長にわたって印刷を連続
的に入れることは困ゲＷないし不可能とされていたから
である。This is because it has been considered difficult or impossible to print continuously over the entire length of the surface of a cylindrical base film.

選ばれる。Separately, an endless transparent printing film 2 is prepared in which unit printing indications 3 are applied at equal intervals over the entire length. As the printing film 2, a film is selected which has printing suitability and compensates for the tensile strength lacking in the base film 1, most preferably a polynisder film or a nylon film.
まず、筒状の基材フィルム１は第１図に示すごとく全長

基材フィルム１は扁平に折り畳むだけで。According to the present invention as described above, the base film 1 formed into a cylindrical shape can be simply folded flat.
あたかも１枚ものと同様になり、基材フィルム１と印刷
フィルム２とを簡単・確実に貼合できる。The base film 1 and the printing film 2 can be laminated easily and reliably as if they were one sheet.
したがって、基材フィルム１の表面に印刷処理された無
端状の包装材Ａが量産可能となり安価に製造できる。Therefore, the endless packaging material A printed on the surface of the base film 1 can be mass-produced and can be manufactured at low cost.
