DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4The utility model provides an embodiment: an easy-tear composite film and a packaging bag, comprising: a packaging bag 1 and a composite film 2, the packaging bag 1 is made of the composite film 2, an easy-tear mechanism 3 is provided on the upper side of one side of the packaging bag 1 for facilitating opening of the packaging bag 1, and a lifting mechanism 4 is provided on the top of the composite film 2 for facilitating carrying the packaging bag 1.

[0022] See also Figure 1-3 In this embodiment, the easy-tear mechanism 3 includes a plurality of cutouts 301, which are equidistantly arranged on one side of the packaging bag 1. The long strip formed by the plurality of cutouts 301 is a tear strip 302. A transparent sticker 303 is adhered to the outer wall of the tear strip 302 away from the packaging bag 1, and the transparent sticker 303 is larger than the tear strip 302. The plurality of cutouts 301 arranged on the packaging bag 1 form a rectangle to form the tear strip 302. Because of the plurality of cutouts 301, the tear strip 302 is in contact with the packaging bag 1. The firmness of the packaging bag 1 is relatively weak. The tear strip 302 can be torn open by tearing the transparent sticker 303. The transparent sticker 303 is larger than the tear strip 302, which makes it convenient to tear the transparent sticker 303 and can block the incision 301 to seal the incision 301. At the same time, the part of the transparent sticker 303 that is larger than the tear strip 302 is bonded to the packaging bag 1 with a relatively small adhesion, which is much smaller than the adhesion between the transparent sticker 303 and the tear sticker 304 and the adhesion between the transparent sticker 303 and the tear strip 302.

[0023] See also Figure 1-3 In this embodiment: the outer wall of the transparent sticker 303 away from the tear strip 302 is adhered with a tear sticker 304, and the adhesion between the transparent sticker 303 and the tear sticker 304 is greater than the adhesion between the transparent sticker 303 and the tear strip 302. The transparent sticker 303 is easily torn through the tear sticker 304, and the adhesion between the transparent sticker 303 and the tear sticker 304 is relatively large, which makes it easy to tear the tear strip 302.

[0024] See also Figure 1 In this embodiment: the lifting mechanism 4 includes a lifting strap 401, the lifting strap 401 is connected to the top of the packaging bag 1, an arc-shaped hole 402 is opened in the middle of the lifting strap 401, and a cotton layer 403 is provided on the top inner wall of the arc-shaped hole 402. By holding the arc-shaped frame 402 by hand, it is convenient to carry the packaging bag 1, and the cotton layer 403 improves the comfort of holding.

[0025] See also Figure 4 In this embodiment: the composite film 2 includes a PET film 5, one side of the PET film 5 is connected to a PE film 6 by solvent-free glue, one side of the PE film 6 is provided with a reinforcing layer 7, and the PET film 5 and the PE film 6 are composited by solvent-free glue. By providing the reinforcing layer 7, the overall quality of the packaging bag 1 can be improved.

[0026] See also Figure 3In this embodiment: a convex strip 8 is connected to the upper part of the inner wall of one side of the packaging bag 1, and a groove 9 is provided on the inner wall of the other side of the packaging bag 1, which is press-fitted with the convex strip 8. If all the items in the packaging bag 1 need to be sealed again after not all of them are taken out, the convex strip 8 can be pressed into the groove 9 to seal the packaging bag 1 again.

[0027] Working principle: when the packaging bag 1 needs to be torn open, pinch the tear sticker 304 and then pull the tear sticker 304, the tear sticker 304 drives the transparent sticker 303, so that the transparent sticker 303 pulls the tear strip 302, because the tear strip 302 is surrounded by a plurality of cutouts 301 and is weakly connected to the packaging bag 1, the tear strip 302 can be easily torn off by pulling to form an opening for taking out the items, when not all are taken out at one time and the items in the packaging bag 1 need to be stored for a second time, the convex strip 8 and the groove 9 can be pressed together to seal, and after sealing, the items can be easily carried through the arc hole 402. The contents not described in detail in this description belong to the prior art known to professional and technical personnel in this field.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
