Description

Technical Field

[0001] The utility model relates to the technical field of correction tapes, in particular to a correction tape core. Background Art

[0002] The working principle of the correction tape core is to transfer the correction coating to the paper surface through friction, forming a smooth white covering layer that is easy to write on. Figure 1 As shown, the correction tape core generally comprises a tape body 1, a supporting winding core 3 and a correction coating 2. The tape body 1 is generally wound on the supporting winding core 3, while the correction coating 2 is coated on one side of the tape body 1.

[0003] Currently, the correction coating 2 is typically made of synthetic resin, rubber, or similar adhesive materials, which are somewhat hygroscopic. However, when the ambient humidity is high, the correction coating 2 absorbs moisture from the air, which may react with certain chemical components in the coating, causing it to become more viscous. Furthermore, since the correction coating 2 is typically applied to one side of the tape 1, it can easily adhere to the back of the next wrap of tape 1 in humid environments, causing portions of the correction coating 2 to adhere to the back of the tape 1. Consequently, the correction coating 2 cannot be released smoothly during use, resulting in intermittent application, which affects the effectiveness and user experience of the correction tape. Utility Model Content

[0004] The utility model provides a correction tape core, which makes it difficult for the correction coating to adhere to the back of the tape body, thereby improving the effect of the correction tape and user experience.

[0005] The technical solution of the utility model is as follows: a correction tape core, comprising a tape body and a correction coating, wherein the correction coating is arranged on one side of the tape body, the tape body comprises a base layer, one side of the base layer is provided with an anti-sticking layer, the other side of the base layer is provided with an adhesion layer, and the correction coating is arranged on the side of the adhesion layer away from the base layer.

[0006] Furthermore, the anti-sticking layer is made of polytetrafluoroethylene material, and the adhesive layer is made of polypropylene material.

[0007] Furthermore, a plurality of protrusions are provided on a side of the adhesive layer away from the base layer, and a top of each protrusion is in an arc-shaped structure.

[0008] Furthermore, a plurality of through grooves are provided on a side of the anti-sticking layer away from the base layer, and the through grooves are spaced apart along the length direction of the anti-sticking layer.

[0009] Furthermore, the corners of each through groove are provided with rounded corners.

[0010] Furthermore, a graphene coating is provided on the side of the anti-sticking layer away from the base layer.

[0011] The working principle and beneficial effects of the utility model are as follows:

[0012] By providing an anti-stick layer, this utility model reduces the adhesive force on the back of the tape, preventing the correction coating from adhering to the back of the tape when the tape is wrapped around the support core, thereby maintaining the integrity of the correction coating surface. This helps ensure smooth release of the correction coating, reduces intermittent application, and improves the effectiveness and user experience of the correction tape. Furthermore, the adhesive layer enhances the adhesion of the base layer, ensuring that the correction coating is unlikely to fall off or adhere to the back of the tape, further enhancing the effectiveness and user experience of the correction tape.

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] refer to Figure 2-4A correction tape core includes a tape body 1 and a correction coating 2. The correction coating 2 is arranged on one side of the tape body 1. The tape body 1 includes a base layer 1001. A release layer 1002 is provided on one side of the base layer 1001. An adhesive layer 1003 is provided on the other side of the base layer 1001. The correction coating 2 is arranged on the side of the adhesive layer 1003 away from the base layer 1001. The base layer 1001 and the release layer 1002 can be connected with a pressure-sensitive adhesive. Similarly, the adhesive layer 1003 can also be connected with the pressure-sensitive adhesive. The pressure-sensitive adhesive can be bonded at room temperature without heating or other treatment. It has strong viscosity and can form a good bonding effect between the base layer 1001 and other layers, and has long-lasting stability. The side with the correction coating 2 is the outer side of the tape body 1, and the release layer 1002 is on the inner side (i.e., the back side) of the tape body 1.

[0021] By providing the anti-sticking layer 1002, the adhesion force on the back of the tape body 1 can be reduced, making it difficult for the correction coating 2 to adhere to the back of the tape body 1 when the tape body 1 is wrapped around the support core, thereby maintaining the surface integrity of the correction coating 2. This helps ensure the smooth release of the correction coating 2, reduces intermittent release, and improves the effectiveness and user experience of the correction tape. In addition, the provided adhesive layer 1003 can enhance the adhesion of the base layer 1001, ensuring that the correction coating 2 is not easily detached or adhered to the back of the tape body 1, further enhancing the effectiveness and user experience of the correction tape. Secondly, a graphene coating can be provided on the side of the anti-sticking layer 1002 away from the base layer 1001. The graphene coating has excellent low friction properties and wear resistance, which not only further improves the smooth performance of the anti-sticking layer 1002, but also enhances the oxidation resistance and durability of the anti-sticking layer 1002, further ensuring the surface integrity of the correction coating.

[0022] Furthermore, the anti-sticking layer 1002 can be made of polytetrafluoroethylene (PTFE), which has an extremely low coefficient of friction and excellent anti-stick properties, effectively reducing adhesion between the correction coating 2 and the back of the tape body 1. Furthermore, PTFE is non-hygroscopic, maintaining excellent anti-stick properties in humid environments. Furthermore, the adhesive layer 1003 can be made of polypropylene, which not only has excellent adhesion but also maintains its adhesive properties in humid environments, making the correction coating 2 less likely to fall off in humid environments, thereby expanding the use cases of correction tape.

[0023] Secondly, a number of protrusions are provided on the side of the adhesive layer 1003 facing away from the base layer 1001. These protrusions increase the contact area between the correction coating 2 and the adhesive layer 1003, further improving the adhesion of the adhesive layer 1003 and making it less likely for the correction coating 2 to fall off, thereby enhancing the integrity of the correction coating 2 on the surface of the tape 1. Notably, because the protrusions are small and have arc-shaped tops, applying the correction coating 2 to the surface of the printed material does not cause any unevenness, maintaining a good smoothness.

[0024] Furthermore, a plurality of through-slots 1004 are provided on the side of the release layer 1002 facing away from the base layer 1001, and each through-slot 1004 is spaced apart along the length of the release layer 1002. This design creates structural gaps in the release layer 1002, reducing the contact area between the correction coating 2 and the back of the tape 1. This reduces friction between the correction coating 2 and the back of the tape 1, making it less likely for the correction coating 2 to adhere to the back of the tape 1 and improving the surface integrity of the correction coating 2. It should be noted that the depth of the through-slots 1004 should not exceed one-fifth of the thickness of the tape 1. This increases the contact area between the correction coating 2 and the back of the tape 1 while also ensuring that the tape 1 does not break during use.

[0025] Finally, the corners of each through groove 1004 are provided with rounded corners. The rounded corner design effectively reduces the sharpness of the edge of the through groove 1004, avoids damage to the surface of the correction coating 2 during use, further improves the integrity of the surface of the correction coating 2, and enhances the user experience.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
