Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of labels, in particular to a high temperature and moisture resistant self-adhesive label. Background Art
[0002] Self-adhesive labels have the advantages of no need to apply glue, paste, or water, no pollution, and save labeling time compared to traditional labels. They have a wide range of applications and are convenient and fast. Self-adhesive labels are a kind of material, also called self-adhesive label material, which is a composite material with paper, film or other special materials as the surface, adhesive on the back, and silicone-coated protective paper as the base paper. After printing, die-cutting and other processing, they become finished labels.
[0003] The application of self-adhesive labels has developed rapidly along with the packaging industry. Self-adhesive labels of ordinary strength cannot meet the needs of special industries, such as meteorology, electricity, petrochemicals and other industries. The working environment in the above fields is mostly high humidity and high temperature. If the pressure applied when sticking the self-adhesive label is not enough or too small, it will cause the adhesion between the adhesive layer and the sticking surface to be insufficient. Long-term use will easily accumulate moisture inside, causing bubbling or even label shedding. Utility Model Content
[0004] The utility model aims to overcome the deficiencies of the prior art and provides a high temperature and moisture resistant self-adhesive label which is easy to stick and can be used for a long time in a high humidity and high temperature environment.
[0005] In order to solve the above problems, the utility model proposes a high temperature and moisture resistant self-adhesive label, including a base film layer, the lower surface of which is compounded with a first adhesive layer, a glass fiber layer, a second adhesive layer and a release film layer in sequence, and the adhesive force of the first adhesive layer is smaller than that of the second adhesive layer.
[0006] As an improvement of the above technical solution, the base film layer is a BOPET film with a thickness of 10-50 μm.
[0007] As an improvement of the above technical solution, the thickness of the first adhesive layer is 20-30 μm, the 180° peeling force is 13-18N, and the annular initial adhesive force is 25-30N.
[0008] As an improvement of the above technical solution, the thickness of the second adhesive layer is 25-40 μm, the 180° peeling force is ≥55N, and the annular initial adhesive force is ≥20N.
[0009] As an improvement of the above technical solution, the thickness of the glass fiber layer is 40-60 μm, and the diameter of the single fiber is 10-20 μm.
[0010] As an improvement of the above technical solution, the release film layer has a thickness of 25-40 μm and a release force of 0.1 N / 25 mm.
[0011] As an improvement of the above technical solution, the upper surface of the base film layer is compounded with an ink printing layer.
[0012] As an improvement of the above technical solution, it also includes an antistatic layer, which is compounded on the upper surface of the ink printing layer.
[0013] The implementation of this utility model has the following beneficial effects:
[0014] The utility model sequentially compounds a first adhesive layer, a glass fiber layer, and a second adhesive layer between the base film layer and the release film layer. Since the first adhesive layer and the second adhesive layer are compounded on both sides of the glass fiber layer, the two adhesive layers penetrate each other on the glass fiber layer, which can improve the adhesion firmness of the base film layer on the glass fiber layer; secondly, the glass fiber has a high strength, and combined with the second adhesive layer with higher adhesion, it can prevent the surface of the object from being affected by wear, scratches and moisture; finally, due to the presence of the glass fiber layer, it can effectively solve the problem of easy bubbling of the label when used in a hot and humid environment. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a cross-sectional view of a self-adhesive label according to an embodiment of the utility model. DETAILED DESCRIPTION
[0016] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.
[0017] See also Figure 1 As shown, an embodiment of the utility model provides a high temperature and moisture resistant self-adhesive label, comprising a base film layer 1, the lower surface of which is compounded with a first adhesive layer 2, a glass fiber layer 3, a second adhesive layer 4 and a release film layer 5 in sequence, and the adhesive force of the first adhesive layer 2 is smaller than that of the second adhesive layer 4.
[0018] The utility model sequentially compounds a first adhesive layer 2, a glass fiber layer 3, and a second adhesive layer 4 between a base film layer 1 and a release film layer 5. Since the first adhesive layer 2 and the second adhesive layer 4 are compounded on both sides of the glass fiber layer 3, respectively, the two adhesive layers mutually penetrate on the glass fiber layer 3, which can improve the adhesion firmness of the base film layer 1 on the glass fiber layer 3; secondly, the glass fiber layer 3 has a high strength, and combined with the second adhesive layer 4 with a higher adhesive force, it can prevent the surface of the article from being affected by wear, scratches and moisture; finally, due to the presence of the glass fiber layer 3, it can effectively solve the problem of easy bubbling of the label when used in a hot and humid environment.
[0019] Furthermore, the base film layer 1 is a BOPET film with a thickness of 10-50 μm. It should be noted that the tensile strength of the base film layer 1 is MD / TD≥170Mpa, and the elongation at break is MD / TD≤200%. The strength and tear resistance of the base film layer 1 match the peeling force after the second adhesive layer 4 penetrates into the first adhesive layer 2.
[0020] Furthermore, the thickness of the first adhesive layer 2 is 20-30 μm, the 180° peeling force is 13-18 N, and the annular initial adhesion is 25-30 N. The first adhesive layer 2 meets the wetting requirements of the glass fiber layer 3. When the thickness of the first adhesive layer 2 is greater than 30 μm, the adhesive layer is too thick and will cause glue overflow; when the thickness of the first adhesive layer 2 is less than 20 μm, the adhesive layer is too thin and cannot completely cover the glass fiber layer 3.
[0021] Furthermore, the thickness of the second adhesive layer 4 is 25-40 μm, the 180° peeling force is ≥55 N, and the annular initial adhesive force is ≥20 N. The adhesiveness of the second adhesive layer 4 can ensure the adhesiveness of the label after it penetrates into the glass fiber layer 3 .
[0022] Furthermore, the thickness of the glass fiber layer 3 is 40-60 μm, and the diameter of the monofilament is 10-20 μm. The glass fiber layer 3 is composed of high-strength glass fibers, which can ensure the strength requirements after glue coating and is more suitable for the second adhesive layer 4 to penetrate into the glass fiber layer 3. When the diameter of the monofilament is less than 10 μm, the strength of the glass fiber layer 3 is insufficient and the label is easily damaged; when the diameter of the monofilament is less than 20 μm, it will affect the penetration speed of the second adhesive layer 4 into the glass fiber layer 3.
[0023] Furthermore, the release film layer 5 has a thickness of 25-40 μm and a release force of 0.1 N / 25 mm. The release film layer 5 is made of PET material, and the tensile strength and tear resistance of the PET material of the release film layer 5 can meet the labeling requirements of the production line.
[0024] Furthermore, an ink printing layer is compounded on the upper surface of the base film layer 1. The ink printing layer is arranged on the base film layer 1 to facilitate printing information on the label.
[0025] Preferably, it also includes an antistatic layer, which is compounded on the upper surface of the ink printing layer.
[0026] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
