Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail with reference to the accompanying drawings. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 3, the embodiment of the present invention discloses a packaging bag for food, including the packaging body made of kraft paper, the packaging body includes a front bag body 1, a back bag body 2, two side bag bodies 3 connecting the front bag body 1 and the back bag body 2, and a sealing edge 5 heat-sealing the top and bottom edges of the front bag body 1, the back bag body 2 and the side bag body 3 together, the sealing edge 5 has two, wherein, the front bag body 1, the back bag body 2, the side bag body 3 and the sealing edge 5 are integrally formed. The contained angle of the folding formation indent of the inside direction of the side bag body 3 orientation packaging body, the formation the contained angle is 60 degrees to 150 degrees preferred, and the too big or the not ductility that does not do benefit to the wrapping bag of angle, owing to be the indent, so the width of the side bag body 3 is adjustable, and this internal splendid attire food of packing has certain elastic expansion space, adapts to different food volume sizes. The folding line 8 is formed in the center of the side bag bodies 3, the packaging body is symmetrical about the folding lines 8 in the centers of the two side bag bodies 3, and the combination edges of the side bag bodies 3 and the front and back bag bodies are relatively sharp, so that the packaging body is convenient to stand. Transparent plastic window 4 has still been seted up on the front bag body 1 surface, transparent plastic window 4 is the rectangle, sets up transparent plastic window 4 and makes things convenient for the user to observe the inside food state of food bag from the outside. The transparent plastic window 4 is adhered to the front bag body 1 in a heat sealing manner, specifically, the front bag body 1 is made of kraft paper, the kraft paper is relatively thick, a hollow groove is formed in the front bag body 1 during manufacturing, then the groove edge of the transparent plastic edge front bag body 1 is heat sealed into a whole, and the edge of the transparent plastic window 4 is fixed in the kraft paper.

In this embodiment, the obliquely transition portion 6 that has between the front bag body 1 and the back bag body 2 all and the sealing edge 5, the transition portion 6 totally four, for four inclined planes, all form the obtuse angle contained angle between this transition portion 6 and the front bag body 1, the back bag body 2 and the sealing edge 5, like this, the part that is close to sealing edge 5 is comparatively narrow, and convenient portable. Wherein, because transition portion 6 is, towards the inboard bending of packaging body, so the 3 width of the side bag body can become narrow gradually in both sides, has obvious folding line that is certain angle between transition portion 6 and the positive bag body and the sealing edge 5, makes junction between the side bag body 3 and the sealing edge 5 forms triangular supporter 7, and in this embodiment, triangular supporter 7 totally 4 is located four angles of wrapping bag, and when conveniently placing, the side bag body 3 part can stabilize straight placing on the platform.

Further, the inner layer of the package body is further provided with a relatively thin cast polypropylene film sheet (not shown in the figure) adhered with kraft paper, and the cast polypropylene film has a function of preventing hot fog and does not obstruct the view of the transparent plastic window 4.

Because two sealing edges 5 are provided, and a plurality of serrated tearing openings are formed on the sealing edge 5 on at least one side, in the embodiment, both sides are serrated tearing openings, and because the production is carried out in batch, both sides are serrated tearing openings, the assembly line production is facilitated.

The above is only the preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, and although the present invention has been disclosed as above by the preferred embodiment, but not limited to the present invention, and those skilled in the art can make some changes or modifications to equivalent embodiments using the above disclosed technical content without departing from the technical scope of the present invention, but all the simple modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention still belong to the technical scope of the present invention.
