Detailed ways

As shown in FIG. 1 , the packaging bag of the present invention includes a bag body 1 and a sealing part 2 . The bag body 1 is used for containing articles, and the bag body 1 can be made of materials such as plastics, paper, and chemical fibers. The packaging bag of the utility model is transparent or translucent or opaque. When no articles are contained, the bottom material of the bag body 1 can be tightly fitted, as shown in FIG. 2A . It may also have a certain space, as shown in Fig. 2B. The bag body shown in FIG. 2A is more portable, and the bag body shown in FIG. 2B can hold more articles.

Figure 2C shows a bottom view of the bag bottom of the bag shown in Figure 2A. The shape shown is the shape of the bottom of the bag after it has been unfolded. This design increases the volume of the bag compared with the bottom of the ordinary envelope in a line.

Looking at Fig. 1 again, the bag body 1 and the sealing part 2 are provided with a pre-cut line 3, the pre-cut line 3 can be formed by a cutter, and punch, cut or roll at a certain distance on the bag body, and the punching and cutting can form through holes, It is also possible to form a semi-permeable hole through only a part of the thickness of the bag material. Rolling may be through only a portion of the thickness of the bag material. The larger the spacing between the through holes or the semi-through holes, or the deeper the inclination, the easier it is for the pre-cutting line 3 to tear, but on the other hand it may also be easily damaged. After the pre-cut line 3 is formed, the sealing part can be easily torn off from the bag body 1 along the pre-cut line 3 . The part of the bag body 1 close to the pre-cutting line 3 is provided with a pre-cutting line handle 4 , and the forming principle of the pre-cutting line handle 4 is the same as that of the pre-cutting line 3 . Preferably, the pre-cut handle 4 is located in the middle of the bag body and is oval.

The closure part 2 has a seal 5 for closing the packaging bag. The sealing member 5 can be a sealing tongue, and the structure of the sealing tongue is that at the opening of the packaging bag, half of the material protrudes, and the length of the protruding part can cover the opening of the packaging bag. For the structure of the tongue seal, please refer to the national standard "GBT16606.3-2009 Express Packaging Products Part 3: Packaging Bags". Further, an adhesive tape 6 is provided on the sealing tongue. One side of adhesive tape 6 is adhered on the sealing tongue, and the other side is covered with a protective film, and under the protective film is an adhesive layer. When the protective film is removed, the adhesive layer is exposed, so that the sealing tongue can be adhered to when the packaging bag is sealed. on the bag. Adhesive tape 6 has the function of anti-tear and anti-destructive, once it is torn, it cannot be restored to its original state.

The sealing member 5 can also be a snap-fit part, for example, on the inner side of the opening of the packaging bag, a protruding part is provided on one side, and a groove for engaging the protruding part is provided on the other side. When sealing the packaging bag, the protruding part and the groove are pressed against each other under force, and the protruding part snaps into the groove, thereby sealing the packaging bag.

The sealing member 5 can also be a drawstring type, and a drawstring is arranged along the opening of the packaging bag, and the opening of the packaging bag can be closed by tightening the drawstring.

The structure and function of each part of the packaging bag will be further described below through the use method of the packaging bag. At the beginning, the staff opens the sealing part 2, and puts the article into the bag body 1 through the sealing part 2. Seal the packaging bag with a seal 5 to prevent the packaging bag from being opened. If the sealing member 5 is a flap, the protective film on the tape 6 is peeled off and the flap is adhered to the packaging bag. Closed and packaged items are sent to their destinations.

The process for the addressee to open the packaging bag is: tear off the sealing part 2 along the pre-cut line 3, then the bag body 1 opens, and the article is taken out from the opening. At the same time, if desired, the pre-cut handles can be torn off to form the handles of the bag, thus becoming a tote bag with handles.

Fig. 3 shows a front view of another embodiment of the present invention. The difference from the first embodiment shown in FIG. 1 is that the pre-tangent line 3 is no longer a straight line, but a curved line, such as a wave. The pre-cut line may not be parallel to the bag opening, but may be oblique, etc. In FIG. 3 , the pre-cutting line 3 protrudes toward the sealing part 2 to form a protrusion, that is, the bag body 1 has a protrusion, and the sealing part 2 has a recess correspondingly. The protrusion is preferably formed in the middle part of the pre-cut line. A pre-cut handle 4 is provided on this protrusion. This modification makes the setting position of the handle more ergonomic and more convenient to use. This modification is especially suitable for the case where the bag body 1 is made of hard material.

Fig. 4 shows a front view of another embodiment of the present invention. In contrast to the second embodiment shown in FIG. 3 , the precut line 3 protrudes towards the bag 1 , so that the bag 1 has a recess. Preferably, the recess is formed in the middle of the precut 3 . The pre-cut handle 4 is arranged on the bag body 1 near the bottom side of the recess. This modification makes the setting position of the handle more ergonomic and more convenient to use. This modification is especially suitable for the case where the bag body 1 is made of hard material.

Fig. 5 shows a front view of another embodiment of the present invention. The difference from the embodiment shown in FIG. 2 is that a cut 7 is formed on the side of the bag body 1 on the precut line 3 . The so-called side of the bag body 1 means that, relative to the shape of the bag body in normal use, the two sides of the bag body 1 are the sides of the bag body 1 when viewed from the front view of the bag body. The precut 3 can be torn more easily due to the inward cut, which is preferably V-shaped. The slit 7 can be provided only on one side of the bag body 1, or both sides.

The above embodiments can be combined arbitrarily, and the structure of the combined utility model is also within the protection scope of the utility model.

The utility model combines two kinds of packaging materials in the prior art into one, which reduces the cost of the packaging materials. At the same time, the packaging process is simplified and the efficiency of packaging operations is improved. Moreover, after the packaging bag of the utility model is opened from the pre-cutting line and the handle of the pre-cutting line, it has the function of a portable shopping bag and can be reused, saving environmental resources.

The above-mentioned embodiments are typical implementations of the present invention, but the utility model is not limited by the above-mentioned embodiments, and any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention, All should be equivalent replacement methods, and all are included in the protection scope of the present invention.
