In the present embodiment, the transverse crease 100 and the longitudinal crease 200 are perpendicular, so the first fold-over area 1100, the first end area 1200, the second fold-over area 1300, the third fold-over area 3100, the second end area 3200, and the fourth fold-over area 3300 are all square. Of course here square encompasses the special case of a square.

Referring to fig. 2, first, a case in the first folded region 1000 is described, where a first end region 1200 partitioned by the longitudinal fold 200 is divided into first end regions, four end points of the first end region 1200 are first points 10, two first points 10 located on the left side of the first end region 1200 respectively extend first folds 300 to the first folded region 1100, similarly, two first points 10 located on the right side of the first end region 1200 respectively extend first folds 300 to the second folded region 1300, in this embodiment, two first folds 300 in the first folded region 1100 are perpendicular to each other and meet at the same point, and similarly, two first folds 300 in the second folded region 1300 are also perpendicular to each other and meet at the same point. The situation in the third folding region 3000 is the same as the situation in the first folding region 1000, and therefore, the description thereof is omitted here.

Referring next to fig. 1 and 3, first, the second folding region 2000 is illustrated, wherein two second creases 400 extend from each of the four first points 10 in the second folding region 2000, and each second crease 400 extends from a third crease 500, the second creases 400 and the third creases 500 extending from the two first points 10 on the left side of the second folding region 2000 form a "[ ]", and the second creases 400 and the third creases 500 extending from the two first points 10 on the left side of the second folding region 2000 form a "[ ]". Similarly, the situation in the fourth folding region 4000 corresponds to the situation in the second folding region 2000, and it should be noted that the position of the lower side of the fourth folding region 4000 corresponding to the second folding region 2000 is the first point 10, and the second fold 400 and the third fold 500 extending from the first point 10 on the same side (i.e., left side or right side) in the fourth folding region 4000 form a "[ ]".

Meanwhile, in order to facilitate sealing, sealing areas 5000 separated by the sealing creases 600 and used for forming the sealing seams are reserved on the left and right sides of the packaging material, and sealing areas 5000 separated by the sealing creases 600 and used for forming the sealing seams are reserved on the upper side or the lower side of the packaging material, although the sealing areas 5000 used for forming the sealing seams may be reserved on the upper side and the lower side of the packaging material at the same time. In order to facilitate drinking of the liquid contained in the packaging container, a marking region 3210 is further disposed in the first end region 1200 or the second end region 3200, in this embodiment, the second end region 3200 is provided with a marking region 3210, and a bottle cap may be disposed in the marking region 3210. Generally, the opening mark region 3210 may be a circular mark for inserting a straw or a cap mark region for installing a cap, and the thickness of the opening mark region 3210 is thinner than other regions (non-opening mark regions) to facilitate opening.

The blank of this embodiment is typically a multi-ply material, with all folds (transverse fold 100, longitudinal fold 200, and first fold 300) being formed by pressing or scoring. The blank comprises seven layers of materials, and the seven layers of materials are sequentially from outside (the outer side of the packaging container after the packaging container is formed) to inside (the inner side of the packaging container after the packaging container is formed): PE layer, adhesive layer, paper layer, PE layer, adhesive layer, aluminum foil layer, adhesive layer, PE layer, and PE modified layer (note: the number of layers of material contained in the blank in the marking region 3210 for inserting a straw or for installing a bottle cap is usually less than seven). The number of layers of the material included in the blank and the specific material used for each layer are not limited in this embodiment.

Referring next to fig. 4 and 5, the packaging container according to the present embodiment is formed from the blank shown in fig. 1, and the process of forming the packaging container may be: after the blank is folded in half, the sealing regions 5000 provided on the upper and lower sides of the blank are bonded to each other, so that the first end face 1 and the second end face 3 are formed, and since the sealing seam 30 is on the side of the second end face 3, the sealing seam 30 is not affected by the sealing seam 30 when the first folded region 1100, the second folded region 1300, the third folded region 3100, and the fourth folded region 3300 are subsequently folded.

Then, the sealing area 5000 on the left side or the right side of the blank is sealed to form a sealing seam 30, after liquid is filled, the sealing area 5000 on the other side is also sealed to form the sealing seam 30, so that a sealed container is formed, of course, if the sealing area 5000 is not arranged, the position needing to be sealed can be sealed through a sealing strip to form the sealing seam 30, referring to fig. 2 and 4, the first end surface area 1200 forms the first end surface 1, the second end surface area 3200 forms the second end surface 3, so that the first end surface 1 and the second end surface 3 are complete end surfaces (see fig. 4 and 5), and no sealing seam exists, so that the situation that the blank cannot be normally folded due to the fact that the sealing seam is too thick when being folded is carried out, or the yield is not high is. Then, the first fold 300 in the first fold region 1100, the second fold region 1300, the third fold region 3100, and the fourth fold region 3300 are folded, so that the second fold region 2000 and the fourth fold region 4000 form the side face 2, and the two second folds 400 and the third folds 500 extending from the same first point 10 in the second fold region 2000 and the fourth fold region 4000 naturally form a diamond shape, so that the appearance is elegant and convenient to hold. Meanwhile, the first end face 1 and the second end face 3 are not provided with any sealing seams (the upper side and the lower side of the blank), so that a larger marking area 3210 can be arranged, more dense liquid such as yoghourt can be contained, when the food is eaten, the marking area 3210 can be directly opened, a spoon or other tableware can conveniently enter a packaging container to obtain food materials, and a bottle cap can be arranged.
