[0036] In one embodiment of the present invention, as Figures 1 to 4 shown, a manufacturing process for a waterproof, high-temperature resistant, printable label is provided, including the following steps:

[0037] S100: Provide a PET film 10, and the PET film 10 has a first surface and a second surface arranged opposite to each other; in this step, it is also necessary to inspect the appearance of the provided PET film 10, that is, if it is found not to meet the set standards, it needs to be rejected to improve the yield of the waterproof, high-temperature resistant, printable labels produced subsequently;

[0038] S200: Print a waterproof coating 21 on the first surface of the PET film 10; the setting of the waterproof coating 21 can isolate the penetration of moisture and play a waterproof role;

[0039] S300: Provide a printable matte film 20, and attach the printable matte film 20 to the surface of the waterproof coating 21; label information can be printed on the surface of the printable matte film 20; in this step, it is also necessary to inspect the appearance of the provided printable matte film 20, that is, if it does not meet the set standards, it needs to be rejected to improve the yield rate of the waterproof and high-temperature resistant printable labels produced subsequently;

[0040] S400: Provide a release film 30, apply an adhesive layer 31 on the second surface of the PET film 10, and then bond the release film 30 to the adhesive layer 31 to form a semi-finished waterproof and high-temperature resistant printable label 200; in this step, it is also necessary to inspect the appearance of the provided release film 30, that is, if it does not meet the set standards, it needs to be rejected to improve the yield rate of the waterproof and high-temperature resistant printable labels produced subsequently.

[0041] Furthermore, the adhesive layer 31 forms a double-sided adhesive function, and the adhesive layer 31 is used to bond the release film 30 to the second surface of the PET film 10. In this way, when in use, the release film 30 can be torn off to bond the adhesive layer 31 to a component of an electronic product.

[0042] S500: Die-cut the outer frame of the semi-finished waterproof and high-temperature resistant printable label 200 to form a finished waterproof and high-temperature resistant printable label 100. The shape of the finished waterproof and high-temperature resistant printable label 100 die-cut in this way is the shape set according to requirements, that is, according to the different environments where the waterproof and high-temperature resistant printable label is applied, its shape is die-cut into a specific shape.

[0043] In subsequent processes, it is also necessary to inspect the finished waterproof and high-temperature resistant printable label 100. If it is qualified, it can be packaged. After final packaging, finished product inspection is also required, such as inspecting the cleanliness and looseness during packaging, whether the quantity of products is correct, whether the packaging label information is correct, etc., to ensure the yield rate of the products after shipment.

[0044] In the manufacturing process of the waterproof and high-temperature resistant printable label according to the embodiment of the present invention, a waterproof coating 21 is first printed on the first surface of the PET film 10, then a printable matte film 20 is attached to the waterproof layer, then a release film 30 is bonded to the second surface of the PET film 10 through an adhesive layer 31, and finally a finished waterproof and high-temperature resistant printable label 100 is formed by die-cutting the outer frame. In this way, the manufacturing process is simple, the production efficiency is high, and the formed waterproof and high-temperature resistant printable label has the functions of waterproof and high-temperature resistance, that is, waterproofing and not easy to fade are achieved through the setting of the waterproof coating 21, and high-temperature resistance is achieved through the setting of the printable matte film 20, and it can remain flat for 30 minutes at a temperature of 120°C.

[0045] Further, in the step S100, the thickness of the provided PET film 10 is between 0.025 mm and 0.1 mm. Specifically, the thickness of the PET film 10 can be 0.025 mm, 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm or 0.1 mm. Within this set thickness range value, the PET film 10 has sufficient toughness or strength, is durable and not easily torn, and will not be difficult to bend due to an excessive thickness value, nor will its small flexibility affect the flexibility of its use.

[0046] Further, in the step S200, the thickness of the waterproof coating 21 is between 0.001 mm and 0.002 mm. Specifically, the thickness of the waterproof coating 21 can be 0.001 mm, 0.0015 mm or 0.002 mm. The thickness of the waterproof coating 21 is reasonably set. On the one hand, it can ensure that it has sufficient thickness to play an effective waterproof function; on the other hand, it also avoids affecting the thickness of the entire waterproof, high-temperature resistant and printable label due to excessive thickness.

[0047] Further, in the step S200, the surface energy after printing the waterproof coating 21 on the first surface of the PET film 10 is between 35 and 42. In this way, the waterproof coating 21 on the PET film 10 can form a better bonding effect with the printable matte film 20, and the waterproof and anti-warping effects at high temperatures are better.

[0048] Further, in the step S300, the thickness of the provided printable matte film 20 is between 0.01 mm and 0.05 mm. Specifically, the thickness of the printable matte film 20 can be 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm or 0.05 mm. The setting within this thickness range value can ensure that the printable matte film 20 has appropriate transparency, and can also form a good display effect. With a reasonable thickness, the product use effect reaches the optimal state.

[0049] Further, in the step S400, the waterproof, high-temperature resistant and printable label semi-finished product 200 is in a strip shape, that is, after the PET film 10, the printable laminated film and the release film 30 are laminated, they all form a relatively long strip shape. Then, several waterproof, high-temperature resistant and printable label finished products 100 are punched out on this strip-shaped waterproof, high-temperature resistant and printable label semi-finished product 200. Then, the outer frame of the waterproof, high-temperature resistant and printable label semi-finished product 200 is the waste material. Thus, in the step S500, the waste material after the outer frame is punched is recycled in an automatic winding manner. It is wound and stored by means of automated mechanical control, which is convenient for storing or reusing the waste material.
