[0001] This utility model relates to the field of stretch film technology, specifically a stretch film with high adhesion. Background Technology

[0002] High-adhesion stretch film is a transparent, elastic, and strong soft plastic film. Its most significant feature is its excellent self-adhesion, which allows it to be cold-stretched longitudinally and laterally without heating, tightly wrapping goods and adhering the outer packaging film layer to the inner layer, making the goods secure.

[0003] Typically, stretch film is self-adhesive, while high-adhesion stretch film usually has tackifiers and adhesives added to further enhance its adhesion. When the high-adhesion stretch film roll has a high degree of adhesion, the following shortcomings will occur during subsequent use: Existing high-adhesion stretch film rolls are usually in the form of a roll, supported by a paper tube inside. Due to its high adhesion, it is not convenient to cut during subsequent use. At the same time, due to the high adhesion, it is not easy to find the initial position of the stretch film roll when using it again, making the stretch film inconvenient to open, and the operation is time-consuming and laborious. In view of the shortcomings of the existing technology, this utility model provides a high-adhesion stretch film to solve the above problems. Utility Model Content

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] This application provides a high-adhesion stretch film, which solves the problems of existing high-adhesion stretch film rolls, which are usually in the form of a roll and supported by a paper tube inside. Due to their high adhesion, they are not easy to cut during subsequent use. At the same time, due to their high adhesion, it is not easy to find the initial position of the stretch film roll when using it again, making it difficult to open the stretch film and causing time-consuming and laborious operations.

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] Example 1:

[0037] This utility model discloses a high-adhesion wrapping film, according to the attached... Figure 1-5 As shown, it includes a wrapping film body 1, an outer frame 2, a first support base 3, a second support base 4, a positioning unit 5, and a cutting unit 6;

[0038] The stretch film body 1 is coated with a high-viscosity adhesive material. This adhesive material has strong adhesion, enabling the stretch film to adhere tightly to the object when wrapped, preventing it from easily coming loose. It is rolled into a cylindrical shape for easy storage and retrieval. When the stretch film is needed, the stretch film body 1 is unrolled from its rolled state, and its high-viscosity adhesive material is used to wrap it around the object to be packaged.

[0039] The outer frame 2 provides a stable support structure for the entire device. The central shaft 21 set on it passes through the axis of the stretch film body 1, so that the stretch film body 1 can rotate around the central shaft 21, which facilitates the use of the stretch film.

[0040] Install the stretch film body 1 on the outer frame 2, ensuring that the central shaft 21 passes through the axis of the stretch film body 1, so that the stretch film body 1 can rotate freely.

[0041] The first support base 3 and the second support base 4 are mounted on the outer frame 2. They provide installation positions and cooperation for the positioning unit 5 and the cutting unit 6, ensuring the stability of these components during operation.

[0042] The positioning unit 5 consists of a first connecting plate 51, a lead screw 52, ​​and a pressure plate 53. The first connecting plate 51 is mounted on the outer frame 2, the lead screw 52 is threaded onto the first connecting plate 51, and the pressure plate 53 is slidably connected below the first connecting plate 51 and rotatably connected to the lead screw 52. By rotating the lead screw 52, ​​the pressure plate 53 can be moved up and down, ultimately clamping the stretch film body 1 between the first support base 3 and the pressure plate 53, thereby limiting the position of the stretch film body 1.

[0043] When it is necessary to limit the position of the stretch film body 1, rotate the screw 52 to move the pressure plate 53 downward, press down on the stretch film body 1, and prevent it from deviating during the wrapping process.

[0044] The cutting unit 6 consists of a second connecting plate 61, a movable rod 62, and a blade 63. The second connecting plate 61 is mounted on the outer frame 2, the movable rod 62 is slidably connected to the second connecting plate 61, and the blade 63 is mounted on the movable rod 62. By pressing down on the movable rod 62, the blade 63 can contact and cut the wrapping film body 1.

[0045] When it is necessary to cut the wrapping film, press down on the movable lever 62 to make the blade 63 cut the wrapping film body 1.

[0046] Example 2:

[0047] This utility model discloses a high-adhesion wrapping film, according to the attached... Figure 1-5 As shown, it includes a wrapping film body 1, an outer frame 2, a first support base 3, a second support base 4, a positioning unit 5, and a cutting unit 6;

[0048] Furthermore, the pressure plate 53 is provided with a lateral support rod 54, which passes through the first connecting plate 51 and extends therefrom. The lateral support rod 54 can enhance the stability of the pressure plate 53 and prevent it from shaking during operation.

[0049] Furthermore, a pressing handle 64 is connected to the movable rod 62, and a spring 65 is fixedly connected between the pressing handle 64 and the second connecting plate 61. The spring 65 can automatically reset the movable rod 62 after it is pressed, making it convenient for the next use.

[0050] The outer frame 2 is provided with a sleeve 22 for limiting the position of the central shaft 21, and a locating pin 23 is threadedly connected between the sleeve 22 and the central shaft 21. The sleeve 22 can limit the position of the central shaft 21, and the locating pin 23 further enhances the stability of the central shaft 21, so that the central shaft 21 can limit the position of the wrapping film body 1.

[0051] When installing the central shaft 21, place it into the sleeve 22, and then screw in the locating pin 23 to fix the central shaft 21 onto the outer frame 2.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
