2. Description of the Related Art In packaging bags for storing foods and the like, various devices have been conventionally devised so that they can be easily opened by hand. For example, by providing a large number of scratches at the end portion of the sealing portion of the packaging bag, providing a cutout of an I-shaped notch or a V-shaped notch, and further cutting the end portion into a mountain shape to form a start portion of opening.

る。However, these opening start portions cannot be formed at any position of the packaging bag, and the range of the forming position is limited by itself. For example, in a back-seal type packaging bag as shown in FIG. 3, an opening start portion can be formed only in the seal portions 11 and 12 of the opening as in the position A, and in the position B and the position C, The opening start part cannot be provided. Therefore, a means for cutting by tearing in parallel with the opening seal portions 11 and 12 cannot be taken. Further, with these conventional methods, it has been difficult to tear straight at the time of opening and cut off the opened end. In addition, providing the opening start portion at the end of the seal portion of the packaging bag requires a certain amount of trouble.

に引き裂くことができる。In the present invention, a packaging bag is formed of a laminate. In the present invention, the laminated body has a large number of fine holes perforated in a high-strength stretched synthetic resin film which is a main body of the laminated body and which is a core, thereby easily tearing into a packaging bag. It is to give the degree. That is, in the packaging bag made of this laminated body, a part of a fine hole is inevitably present at the peripheral end of the packaging bag, and that part becomes a tearing start point. It can be torn by hand from any point and can be torn in a straight line.

ましい。In the present invention, various methods can be considered for the perforation processing for perforating a large number of fine holes in the stretched synthetic resin film.
That is, a method of piercing by irradiating a laser beam, a method of piercing and melting a needle heated above the softening point of a synthetic resin film, a method of rotary die cutting, a method of passing between rollers having a sawtooth file-shaped surface. For example, a method of forming a hole by pressurizing and heating with an emboss roller can be considered. In the present invention, a stretched synthetic resin film is used in which a needle having a temperature equal to or lower than the softening point of the synthetic resin film is pierced to form a burst-like hole. The shape of this perforation is x shape or *
A burst shape such as a shape is preferred. The size of the hole is preferably 0.1 to 2.0 mm. Also, a lattice shape of 1.0 to 10 mm is preferable as the hole interval.

この際、穿孔ロール21の針23の温度は、延伸合成樹脂フ
ィルムの軟化点以下の温度に維持する。FIG. 4 shows a preferred example of the perforating process of the stretched synthetic resin film in the present invention. This perforation process is performed by passing a stretched synthetic resin film 24 between a perforation roll 21 having a large number of needles 23 planted on its surface and a rubber roller 22.
At this time, the temperature of the needle 23 of the perforation roll 21 is maintained at a temperature equal to or lower than the softening point of the stretched synthetic resin film.

〜2.0mmφである。By piercing the stretched synthetic resin film with a needle having a temperature equal to or lower than the softening point of the stretched synthetic resin film, the pierced portion becomes a burst shape having a X shape or a * shape. In the perforated stretched synthetic resin film, since a burst-shaped hole is formed over the entire surface, a crack exists based on the peripheral end of the synthetic resin film as well as the burst-shaped hole. It is easy to tear straight from any part of the body. Immediately after the above-described perforation, the place where the needle is stabbed is raised, but the raised portion becomes flat in the winding process. Therefore, there is no hindrance in the subsequent printing process and laminate manufacturing process, and the printing ink and adhesive do not ooze out of the holes. The cross section of the needle used for perforation is arbitrary, but triangular or square needles are preferred. The diameter of the part in contact with the synthetic resin film is 0.1mmφ
~ 2.0mmφ.

いていけるので、直線状に引き裂きやすい。(Effects of the Invention) In the packaging bag of the invention, a large number of fine holes are formed in the high-strength stretched synthetic resin film serving as the core of the laminated body constituting the packaging bag over the entire surface. Since there is a fine hole everywhere in the part, and this part is the opening start point, it can be easily teared open from any position of the peripheral edge by hand, and the tear part is straight Become. Therefore, unlike the conventional easy-open packaging bag, this packaging bag does not need to provide an opening start portion (opening notch) in the seal portion of the opening, and can be opened from a position other than the seal portion. Particularly, it is useful for a back seal type as shown in FIG. In addition, since the above-mentioned fine holes were pierced by a needle piercing at a temperature equal to or lower than the softening point temperature of the synthetic resin film, there was a linear tear in a burst shape such as an X shape or an * shape, so that the opening portion was opened. It is suitable as. In addition, since the linear cracks can be torn one after another, it is easy to tear linearly.
