Description

A double-layer sealed plastic packaging bag

technical field

The utility model relates to the field of packaging, in particular to a double-layer sealed plastic packaging bag, which is suitable for packaging powdery objects. the

Background technique

At present, known plastic packaging bags are generally single-layer sealed packaging bags, and some of the sealing parts have small openings, and some do not. Generally, it is opened by tearing by hand or cutting with scissors. However, there are many detailed everyday problems that arise when and after opening plastic bags. The problems are as follows: first, tearing by hand or cutting with scissors is not appropriate to grasp the size of the opening; second, the opening of the bag is too large, and it is easy to accidentally pour out the contents of the plastic bag; third, the opening of the bag is too large. If it is too small, the contents in the bag should not be poured out or poured out slowly; Fourth, when taking a large amount of contents in the plastic bag, the opening of the bag should be slightly larger, and when washing a small amount of contents in the plastic bag, the opening of the bag should be slightly smaller A little, but the size of the opening is inconvenient to adjust after the general opening of the current plastic packaging bag. Fifth, if the plastic packaging bag is opened, if the air is humid or placed in a humid place, the substances in the bag will be more likely to be damp or some substances will agglomerate. Damp or agglomerated substances should not be poured out of the bag when used, it is easy to pour too much, and some are not easy to disperse and dissolve quickly; Openings are more susceptible to moisture or are more likely to be splashed with water and cause dampness. When the powdery substance is poured out of the wet opening, the powdery substance is likely to stick to the opening of the bag and cause the mouth to be blocked, so it is not suitable to pour out; seventh, the bag should not be sealed after opening, and the substance contained in the bag is easy to spill, so it is not suitable for carrying . the

Detailed ways

Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail. the

Example 1

As shown in Figures 1 to 3, a double-layer sealed plastic packaging bag includes a packaging bag body 5 and a PVC zipper 3 for sealing the packaging bag body 5, and the PVC zipper 3 is close to the tearing edge of the packaging bag body 5 One side of the bag is provided with a sealing line 2, and the side of the packaging bag body 5 is provided with an opening 1, and the opening 1 is located between the sealing line 2 and the PVC zipper 3. The packaging bag body 5 is also provided with a packaging bag carrying hole 6 . The PVC zipper 3 is also provided with a zipper puller 4, and the small opening 1 is one, which can reduce the probability that an object will be torn apart by scratching at the small opening 1 during transportation and the like. When the PVC zipper 3 was closed, the zipper slider 4 was close to the side of the opening 1. The PVC zipper 3 is parallel to the sealing line 2. The distance between the PVC zipper 3 and the sealing line 2 is 10 mm to 20 mm, which is convenient for tearing by hand or cutting with scissors from the opening 1 .

As shown in Figure 2, open the sealing line 2 (upper seal) from the small opening 1 by hand or cut with scissors, pull the zipper puller 4 of the PVC zipper 3 to open the closed PVC zipper 3 (lower seal), Control the opening size of the PVC zipper 3 (lower seal) by pulling the zipper puller 4 to grasp the required opening size of the plastic packaging bag. Complete the closure of the plastic packaging bag. the
