Through adopting above-mentioned technical scheme, through setting up the thickening portion to make it can consolidate the position of tether portion, avoid it to take place damaged problem easily.

The utility model is further configured to: the thickness of the bag sealing part is more than twice of the thickness of the bag body.

The utility model is further configured to: the bag body is folded below two ends of the bag sealing part to form a sigma-shaped folding part.

The utility model is further configured to: the bag body, the bag sealing part and the thickened part are all made of high-density polyethylene materials.

In conclusion, the utility model has the following beneficial effects:

through setting up the portion of restricting to when making this plastic film bag ordinary transport, can establish the bag body cover in the outside by the protection thing, then make the expansion end of portion of restricting to drop from the bag body through manual mode, twine through the portion of restricting and tie a knot after that, thereby make the bag body be difficult for coming off from by the protection thing.

Detailed Description

The utility model is described in detail below with reference to the figures and examples.

Example (b):

a novel plastic film bag is shown in figures 1 and 4 and comprises an annular bag body 2 and a bag sealing part 1 with one end closed, wherein the thickness of the bag sealing part 1 is larger than the double thickness of the bag body 2, the bag body 2 is folded below two ends of the bag sealing part 1 to form a folding part 5 in a sigma shape, one end of the bag body 2, which is far away from the bag sealing part 1, is at least integrally formed with two rope tying parts, each rope tying part is provided with a movable end, and the movable end is attached to the bag body 2.

As shown in fig. 2, 3, 5 and 6, the cutting horizontal grooves 3 that two sets of even intervals set up are seted up on the one end periphery wall that bag portion 1 was kept away from to the bag body 2, the number of every group cutting horizontal groove 3 is a plurality of, and the one end that bag portion 1 was kept away from to the bag body 2 has seted up two sets of cutting vertical grooves 4, tether portion is formed on the bag body 2 through cutting vertical grooves 4 and cutting horizontal grooves 3, and bag body 2 length between adjacent cutting horizontal grooves 3 and the adjacent cutting vertical grooves 4 is less than the ductility fracture length of cutting vertical grooves 4 and cutting horizontal grooves 3, bag body 2 that lies in simultaneously between two sets of cutting horizontal grooves 3 is along its thickness direction fixedly connected with thickening portion 6, the bag body 2, bag portion 1 and thickening portion 6 all adopt the high density polyethylene material.

When people need to obtain the plastic film bag, people firstly send high-density polyethylene particles into an extrusion blow molding machine for processing, and carry out drawing and blow molding to obtain a plastic film, then, thickened parts 6 with the same material at two ends are bonded at one end of the plastic film, the distance between the two thickened parts 6 is equal to the width of the plastic film minus one half of the width of the two thickened parts 6, and people send the plastic film roll into a hot press machine to press a plurality of cutting transverse grooves 3 and cutting vertical grooves 4 on the plastic film between the adjacent thickened parts 6 through the hot press machine, then, people carry out thermal bonding on the length direction of the two plastic films through a thermal bonding process to form a bag body 2, and the bag body 2 is folded and punched in the width direction to form a sigma-shaped folding part 5, and the sealing part is formed at one end of the plastic film without the thickened parts 6 through hot melt adhesive bonding, thereby obtaining the whole plastic film bag.

When people need to use the plastic film bag, the folding part 5 can be opened through the friction force of the bag body 2 by kneading the folding part 5, the folding part 5 can save area after the plastic film bag is folded and stored, and after the folding part 5 is unfolded, the folding part 5 can unfold the inside of the bag body 2, so that air enters the bag body 2, then people sleeve the bag body 2 outside the rolled yarn, then people tear the bag body 2 in a manual mode, so that under the guiding action of the cutting vertical groove 4 and the cutting transverse groove 3, people can tear the rope tying part easily, the thickened part 6 at the root part is firmer, so that people can wind the two rope tying parts outside the rolled yarn, and can also carry out knotting, the plastic film sleeve is firmer, the problem of separation is not easy to occur.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
