ている。2. Description of the Related Art Conventionally, a bag-like package is easily opened by a method of providing perforations, or laminating a film having scratches or perforations in a certain direction of the film or a film having a significantly different tear strength in vertical and horizontal directions. There was a method in which the tear direction was specified and used. There is also a method of obtaining an easy-opening property by cutting the heater or providing irregularities on the heater surface to form an adhesive portion and a non-adhesive portion. For example, Japanese Unexamined Patent Publication No. Hei 8-301307 discloses a bag-like package in which a film made of a thermoplastic resin is folded in two, and the product is filled in a bag formed by thermally bonding (heat-sealing) the film overlapping surfaces on three sides. A thermoplastic nonwoven fabric having a lower melting point than the film is interposed between the film overlapping surfaces on one side serving as an opening and thermally bonded at a low temperature to melt the nonwoven fabric and partially overlap the film overlapping surface. Are described as being adhered.
This weakens the adhesive strength of the thermal adhesive band at the opening to facilitate opening. On the other hand, in Japanese Utility Model Publication No. 60-25400, a plastic film is vertically folded, the vertical edges of the superimposed films are heat-sealed to each other, the opposing sides are folded in a gusset shape, and cut at two locations in the vertical direction. Then, in a bag-like package in which the product is stored and the vicinity of these transverse cut portions is heat-sealed, a plastic film is stretched in the vertical direction in advance, and cuts are made at two places of the transverse cut portions. Put in to form an ear,
It describes that the bag is torn in the longitudinal direction from the ear part. Further, Japanese Patent Application Laid-Open No. 7-300142 describes that a handle portion is formed by being connected to a thermal bonding band on the top side of two thermal bonding bands orthogonal to a fold line of a gusset-shaped bag storing a product. Have been. Additionally, perforations are provided adjacent to the thermal adhesive strip to facilitate opening.

In addition, as a method of bonding the bonding portion, thermal bonding using the thermal bonding property of the plastic film itself is often used because the device is simple and easy to handle, and if there is printing on the bonding surface, the bonding strength is low. No printing was applied to the adhesive part due to the decrease. In the present invention, the phenomenon that the adhesive strength is reduced by printing on the adhesive surface is utilized, and ink is applied in an appropriate distribution by printing to at least one portion of the heat-bonded portion, and non-adhesive is performed by this ink. The adhesive strength is adjusted by adjusting the ratio between the ink application area and the non-application area, thereby obtaining easy-openability.

Let it. At this time, by applying the printing ink in a predetermined pattern to the adhesive portion of the film in advance, since the adhesive surfaces of the film at that portion do not directly contact each other, the ink applied portion is not bonded, and Heat bonding at the part. Making use of this, a weak adhesive band is created by distributing the adhesive surface where the films adhere to each other and the non-adhesive surface coated with ink at an appropriate area ratio, and the adhesive strength is changed by changing the ink printing area or printing pattern. Adjustments can be made. For example, a grid-like printing is performed within a certain range, and the width of the grid is changed to be large, so that the area of the non-printing surface is relatively reduced and the adhesive strength is weakened. Also, the opening property can be changed by changing the printing pattern. The printing pattern at this time has various shapes such as a grid, a circle or a polygon, a straight line or a wavy line arranged at an arbitrary angle.

Even if the bag is shocked when taken back after purchase and the adhesive is peeled off, if this adhesive method is used for the handle portion, it is possible to prevent damage due to product drop or the like just by opening the adhesive portion. Further, when provided on the handle portion, the product remains in a bag state even after use of the product, so that the remaining product in the bag state can be stored and reused for another use, leading to recycling. Conventional products could not be taken out without breaking the bag, so the bag after taking out the product turned into garbage and was not suitable for storing the surplus product.

に開放することができる。Embodiment 2 FIGS. 2 and 3 show an example of a package using a gusset bag made of a plastic film according to a second embodiment of the present invention. The difference between the gusset bag-shaped package and the first embodiment is the structure of the top. In this example, the reinforcing plate 11 is bonded to the film 16. The reinforcing plate 11 is made of plastic, paper, or the like. The heat-bonding band 13 forms a weak bonding band including a non-bonding portion 14 formed of printing ink and a bonding portion 15 which is in direct contact with the film surfaces and is heat-sealed. As a printing pattern for forming the non-adhesive portion 14, a repetitive pattern similar to that shown in FIG. 4 can be used. In FIG. 4, locations where thermal bonding is not performed are indicated by thick solid lines for convenience, but actually, the inner surfaces of the films are merely in contact with each other. In the illustrated example, the weak adhesive band 13 is applied to the lower region of the handle portion, but may extend to the vicinity of the top opening. In this case, heat bonding is not performed near the top opening, and The adhesive band 13 increases the area of the non-adhesive portion 14 made of the printing ink upward, and increases the adhesive portion 15 between the films downward,
The easy-opening property can be improved while sufficiently securing the sealing strength. According to this configuration, by holding the top opening with both hands and pulling it apart, the weak adhesive band can be peeled off and the package can be easily opened.
