[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 3 This utility model provides a technical solution: a stretch wrap film that is easy to cut, comprising a wrap film body 1 and a cutting line 3. This technical solution is an improvement on the wrap film in the patent literature mentioned in the background art. In this technical solution, the wrap film body 1 is provided with connecting portions 2 arranged at equal intervals. The connecting portion 2 includes a connecting film 21, a connecting piece 22 and a protective piece 23. A cavity 211 is formed in the connecting film 21. One end of the connecting piece 22 is fixedly connected to one side of the cavity 211. The cavity 22 has the function of hiding the connecting piece 22. The two ends of the connecting piece 22 are... A protective sheet 23 is attached to the side by adhesive. The protective sheet 23 can be made of silicone paper and is attached to the connecting sheet 22 to protect the adhesive. The cutting line 3 is arranged around the outside of the connecting film 21 and opposite to the cavity 211. The cutting line 3 adopts a common point-break shape, which is easy to tear manually. After the film body 1 is torn, the corresponding connecting film 21 will be divided into two parts. At the same time, the connecting sheet 22 in the cavity 211 will be exposed. When the protective sheet 23 is peeled off manually, the adhesive will be exposed, which makes it easy to bond the tail of the film body 1 on the wrapped product to the outer wall of the film body 1.

[0024] Furthermore, the connecting film 21 is provided with a number of equally spaced partitions 212 located in the cavity 211. The partitions 212 divide the cavity 211 into a number of sub-gaps 2111. A connecting piece 22 is provided in each sub-gaps 2111. In other words, the cavity 211 is provided with a number of independent connecting pieces 22. When the wrapping film body 1 wraps the irregularly shaped product, the cut line 3 on the connecting film 21 will be in a bent and deformed state. However, the individual connecting pieces 22 will not be affected by the bending and deformation, so that the tail of the wrapping film body 1 can be fully and tightly bonded to the outer wall of the wrapping film body 1.

[0025] The two sides of the septum 212 and the two side walls of the cavity 211 located on one side of the cut-off line 3 are fixedly connected. That is, when a connecting membrane 21 is separated from the cut-off line 3, the septum 212 and the connecting piece 22 will be together.

[0026] In this embodiment, the outer side of the protective sheet 23 located on one side of the connecting piece 22 and one side inside the cavity 211 are fixedly connected. The cavity 211 is connected to the protective sheet 23 and the connecting piece 22 at the two sides of the cut-off line 3, respectively. The purpose of this arrangement is that when one connecting film 21 is torn open, the protective sheet 23 on one side of the connecting piece 22 will be automatically peeled off, while the protective sheet 23 on the other side remains attached to the connecting piece 22. This arrangement eliminates the need for manual peeling of the protective sheet on one side of the connecting piece 22, thus improving the convenience of bonding.

[0027] Furthermore, a flap 231 is provided on one side of the protective sheet 23 connected to the cavity 211. One side of the flap 231 is fixedly connected to one side of the cavity 211. The function of the flap 231 is to improve the smoothness of the protective sheet 23 being peeled off, and to avoid the problem of the protective sheet 23 being torn and difficult to peel off completely from the connecting piece 22.

[0028] In this embodiment, a ring rib 213 is fixedly sleeved on the outer periphery of the connecting membrane 21. The cross-section of the ring rib 213 is triangular. The function of the ring rib 213 is to improve the strength of the connecting membrane 21 and avoid tearing when it is torn. In other words, the setting of the ring rib 213 makes it easier for the connecting membrane 21 to be torn from the cutting line 3, and the connecting membrane 21 is approximately in a complete state after being torn.

[0029] Furthermore, there are two ring ribs 213, which are located on both sides of the cut-off line 3, making it more convenient to manually tear open the connecting membrane 21.

[0030] Working principle: After the product is wrapped with the stretch film body 1, the connecting film 21 is manually torn open by the two ring ribs 213. At this time, the connecting piece 22 in the cavity 211 is exposed, and the protective piece 23 on one side of the connecting piece 22 is peeled off. Then, the connecting piece 22 with exposed adhesive is manually attached to the outside of the stretch film body 1. At this time, the entire stretch film body 1 is in a state of tightly wrapping the product.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
