[0023] Example

[0024] like Figure 1 As shown, a roll protective film structure proposed in this embodiment includes a protective film body 1, and a lower release film 2 is provided at the lower end of the protective film body 1. A handle 11 is provided on the side of the protective film body 1, and a ribbon 12 is provided on the surface of the handle 11. Preferably, the ribbon 12 covers the surface of the handle 11, and the handle 11 is made integrally with the protective film body 1.

[0025] At present, the size of the ribbon 12 on the handle 11 of the protective film product is unstable and cannot meet the quality requirements. Furthermore, in order to detect whether the size of the ribbon 12 is stable and meet the production requirements, a limit mark is provided on the lower release film 2 at the position of the handle 11, and the limit mark is provided on the side of the handle 11. The first limit mark 3 and the second limit mark 4 are used as marks for comparison of the size deviation of the ribbon 12.

[0026] Preferably, the limit mark includes two, namely, a first limit mark 3 located at the upper end of the handle 11 and a second limit mark 4 located at the lower end of the handle 11. The first limit mark 3 is used to mark and compare the maximum size position of the ribbon boundary 121, and the second limit mark 4 is used to mark and compare the minimum size position of the ribbon boundary 121. If the ribbon boundary 121 exceeds the first limit mark 3 and the second limit mark 4, it can be determined that the quality is unqualified and picked out.

[0027] Preferably, the shape of the limit mark can be a combination of one or more of numbers, letters, and patterns. Figure 1 As shown, the limit mark is a vertically arranged "I"-shaped notch mark. Specifically, the width of the "I"-shaped notch mark is 0.01-2.0 mm; and the length is 0.5-10.0 mm.

[0028] Preferably, the first limit mark 3 and the second limit mark 4 are at different distances from the side of the protective film body 1. They are used to mark and compare the boundaries of the color band 12, so that the staff can identify products with substandard quality.

[0029] Preferably, the protective film body 1 is a PE film layer, a PET film layer or a PP film layer.

[0030] Preferably, the release force between the lower release film 2 and the protective film body 1 is 25-30 g / 25 mm.

[0031] Preferably, the thickness of the lower release film 2 is 35-50 um.

[0032] In the present application, the roll protective film and the die-cut protective film products are harvested in a barrel shape, which is convenient for installation on automated equipment such as film laminating machines.

[0033] In actual production, the die-cutting of the roll film and the marking of the limit mark on the lower release film 2 can be performed synchronously or crosswise, and finally the feature of the roll protective film product having a special mark is realized, which is convenient for the staff to identify and detect.

[0034] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
