Embodiment Construction

[0013] like figure 1 Shown, a kind of liquid plastic packaging bag, comprises square packaging bag body 1, has gap 2 and gap 3 on the two sides of packaging bag body 1 corner, has curved strip-shaped hole between two gaps, so The two ends of the above-mentioned notch and the curved strip hole are adjacent to each other; the notch is arranged on the sealing edge of the packaging bag, and the curved strip hole communicates with the space containing the liquid in the packaging bag, and the diameter of the connected through hole 41 is less than or equal to 3mm.

[0014] The notch 2 and the notch 3 are pointed notches, and can also be designed as arc-shaped notches.

[0015] like figure 2 As shown, the curved strip-shaped hole is arc-shaped or a vertical linear hole 4 with a curved angle.

[0016] The two ends of the vertical linear hole 4 have sharp points, which can facilitate the tearing of the packaging bag.

[0017] The vertical linear hole 4 communicates with the space co...

Abstract

The invention provides a liquid plastic packaging bag comprising a square packaging bag body. Gaps are formed in the two sides of one corner of the packaging bag body, a curved strip hole is formed between the two gaps, and the gaps are adjacent to and opposite to the two ends of the curved strip hole; and the gaps are formed in the sealing edges of the packaging bag, the curved strip hole communicates with a space in which liquid is contained in the packaging bag, and the communicating hole diameter is smaller than and equal to 3 mm. According to the liquid plastic packaging bag, when a package needs to be opened, only small force is needed for opening the packaging bag; and as the communicating hole diameter of the curved strip hole and the space in the packaging bag body is smaller than3 mm, too much liquid in the packaging bag is prevented from being extruded out even though too large force is applied.

Description

technical field [0001] The invention relates to a liquid plastic packaging bag, which belongs to the technical field of food packaging. Background technique [0002] Now some liquid food packaging generally adopts the structure of direct sealing of square plastic bags, such as milk packaging. But for this kind of packaging seal, it is very easy to squeeze out the liquid in the packaging bag after people open it. If the packaging bag has high strength and strong toughness, it is very difficult to tear the plastic packaging bag. Turn it on. If you don't use tools, when you directly tear it open with your bare hands, the liquid inside will flow out from the torn mouth under the squeeze force. If the torn mouth is larger, the liquid that flows out is often very large. SUMMARY OF THE INVENTION [0003] The present invention provides a liquid plastic packaging bag, which can solve the above-mentioned defects. The packaging bag can be opened without using tools, and a large amo...
