Description
Technical Field
The utility model particularly relates to a four-edge sealed self-standing packaging bag.
Background
At present, most of traditional packaging bags are not convenient to stand by themselves under the prior art, so that liquid or objects in the packaging bags easily escape out due to inclination, great waste is caused, and the stereoscopic impression is avoided.
Disclosure of Invention
In view of the above, an object of the present invention is to provide a four-sided sealed self-standing packaging bag having high structural strength and enhanced three-dimensional appearance.
In order to solve the technical problem, the technical scheme of the utility model is as follows:
a four-side sealed self-standing packaging bag comprises a bag body, a bottom sheet and a built-in zipper, wherein the bottom sheet is positioned at the lower end of the bag body and is in hot-press sealing connection with the bag body; the bag body is formed by performing heat sealing on two sides of two inserting pieces, the sealing edge after heat sealing extends to the lower end of the bag body, the negative comprises a negative body and a round thick pad which is integrally formed with the negative body, four corners of the negative body are corner sealing ends which are subjected to heat sealing with the two inserting pieces, and two side edges of the negative body are edge sealing ends which are subjected to heat sealing with the bottom edges of the two inserting pieces.
Preferably, the tab is a puncture resistant bi-directional polyamide layer.
Preferably, the lower end of the insert is heat-sealed with the corner sealing end of the bottom sheet, and then the insert and the bottom sheet are heat-sealed with each other.
Preferably, the circular thick pad is located in the middle of the bottom plate body and is arranged in a downward protruding mode.
The technical effects of the utility model are mainly embodied in the following aspects: according to the utility model, the four corner sealing ends of the bottom sheet are subjected to heat sealing with the lower ends of the two inserting sheets, and then the edge sealing ends are subjected to heat sealing with the edge parts of the lower ends of the two inserting sheets, so that the two inserting sheets can be connected to form a bag body, and then the corner heat sealing parts of the two inserting sheets are subjected to hot-press sealing again, so that the bag body can be supported by the bottom sheet, can be unfolded and can stand by itself, the structural strength is high, and the stereoscopic impression of the bag body is enhanced.

Detailed Description
The following detailed description of the present invention is provided to facilitate the understanding and appreciation of the technical aspects of the present invention in connection with the accompanying drawings.
In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description of the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, the detailed description thereof is omitted in this embodiment.
Examples
A four-side sealed self-standing packaging bag is shown in figures 1-3 and comprises a bag body 1, a bottom sheet 2 which is positioned at the lower end of the bag body 1 and is in hot-press sealing connection with the bag body 1, and a built-in zipper 3 which is positioned at the upper end of the bag body 1; the bag body 1 is formed by heat-sealing two sides of two inserting sheets 11, and the sealed edge after heat-sealing extends to the lower end of the bag body 1,
as shown in fig. 4, the film 2 includes a film body 21 and a circular thick pad 22 integrally formed with the film body 21, four corners of the film body 21 are corner sealing ends 211 for performing heat sealing with the two insert sheets 11, and two side edges of the film body 21 are edge sealing ends 212 for performing heat sealing with bottom edges of the two insert sheets 11. The circular thick pad 22 is located in the middle of the bottom sheet body 21 and protrudes downward, and specifically, the bottom sheet 2 can be prevented from being worn by the circular thick pad 22.
In this embodiment, the tab 11 is a puncture resistant bi-directional polyamide layer.
In this embodiment, the lower end of the insert 11 and the corner sealing end 211 of the base sheet 2 are heat sealed and then heat sealed to each other.
The technical effects of the utility model are mainly reflected in the following aspects: according to the utility model, the four corner sealing ends of the bottom sheet are subjected to heat sealing with the lower ends of the two inserting sheets, and then the edge sealing ends are subjected to heat sealing with the edge parts of the lower ends of the two inserting sheets, so that the two inserting sheets can be connected to form a bag body, and then the corner heat sealing parts of the two inserting sheets are subjected to hot-press sealing again, so that the bag body can be supported by the bottom sheet, can be unfolded and can stand by itself, the structural strength is high, and the stereoscopic impression of the bag body is enhanced.
The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all the technical solutions formed by equivalent substitutions or equivalent changes are within the scope of the present invention as claimed.
