Description

Technical Field

[0001] This utility model relates to the field of release paper separation technology, specifically to a release paper that is easy to tear. Background Technology

[0002] Release paper, also known as silicone paper or anti-stick paper, primarily serves to isolate sticky substances, such as adhesive tape. It is generally peeled off and discarded during use. Its most widespread application is as a carrier for adhesive tapes or other adhesive products, and it also has applications in the food and medical industries.

[0003] Existing release paper includes a base layer, which is coated with a film and then dried; then a silicone oil layer is coated and dried to form the finished product.

[0004] In most conventional products, release liner is bonded to the substrate to protect it. The silicone oil layer on the release liner primarily prevents adhesive from adhering to the backing paper, ensuring the product remains clean and intact before use. The silicone oil coating reduces the surface tension of the adhesive material on the substrate, allowing for smooth peeling without residue.

[0005] References:

[0006] CN201620658926.4 A high-temperature pressing release paper; it describes that the release adhesive layer is provided with at least 3 equidistant splitting lines, which can be folded at a certain ratio and can be easily torn apart when the release paper completes its processing task. Multiple sets of splitting lines are provided and arranged in parallel.

[0007] CN202322002761.8 Easy-tear foldable release film; with multiple easy-tear lines spaced apart on the body and extending axially, each easy-tear line having the same axial length as the body, and each easy-tear line consisting of alternating breaks and connections, this release film structure allows the film to be easily torn open using the easy-tear lines, unfolded for use, and easy to store; it can be bonded simply by tearing off the release paper.

[0008] Existing release liner break points are all the same length as the width of the release liner or roll film, with multiple sets set in parallel, equal length, and equal spacing. While these break points do facilitate the separation of the release liner from the front and back, they are not conducive to separating the release liner from the attached material. When the adhesive edge between the attached material and the release liner cannot be raised, such as after the release liner has been cut, the attached material cannot bend to form a raised edge that separates from the release liner, making manual peeling of the attached material from the release liner impossible and hindering rapid separation.

[0009] To address these issues, we offer an easy-to-tear release liner. Utility Model Content

[0010] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an easy-to-tear release paper to solve the technical problem of not being able to quickly separate the attached material from the release paper.

[0011] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an easy-to-tear release paper, comprising:

[0012] The formed paper includes a paper layer, and a coating layer of the same thickness is provided on the upper and lower surfaces of the paper layer. The surface of the coating layer located on the upper surface of the paper layer is coated with a silicone oil layer.

[0013] At least two sets of tear lines are provided on the forming paper, and the two sets of tear lines intersect at the ends; an adhering substance is adhered to the silicone oil layer, and one set of tear lines passes through the area covered by the adhering substance on the release paper to separate the adhering substance from the silicone oil layer.

[0014] In a further technical solution, the two sets of tear lines include tear line one and tear line two, wherein multiple sets of tear line one and tear line two are provided; tear line one is used to separate the front and rear release paper, and tear line two is used to separate the attached material and the release paper.

[0015] Notches are provided at both ends of the first tear line, and the first tear line is connected to the middle of the notch; and the notches are located on both sides of the release paper.

[0016] In a further technical solution, one end of the second tear line intersects the first tear line at a set of notches, and the second tear line is one of a straight line, a curve, or a broken line.

[0017] The other end of tear line two intersects with the next set of tear lines one.

[0018] In a further technical solution, the attachment includes an adhesive portion and a non-adhesive portion, and multiple attachments are provided; each attachment is located between adjacent tear lines.

[0019] A lateral notch is provided on the release paper. The lateral notch is located on one side of the non-adhesive portion, and the non-adhesive portion extends above the lateral notch. The adhesive portion does not overlap with the lateral notch.

[0020] In a further technical solution, the outer side of the formed paper is provided with a reserved side edge, which does not contact the attached material;

[0021] The outer side of the reserved side is either a straight line, a curve, or a broken line.

[0022] In a further technical solution, a base layer is provided on the side of the formed paper facing away from the attached material; the middle of the formed paper protrudes upward; and a filler is provided between the formed paper and the base layer.

[0023] The two sides of the protrusion are fitted with filler material two; the top height of the formed paper of filler material two and filler material one is the same.

[0024] In a further technical solution, the second filler is foam material.

[0025] Compared with existing technologies, it has the following advantages:

[0026] This invention employs at least two sets of tear lines, each serving a different function. One set passes through the adhesive area on the release paper. This method allows for unidirectional tearing of the release paper, enabling rapid separation of the release paper and the adhesive.

[0027] This invention involves adding a non-adhesive portion to the attached material. This non-adhesive portion does not adhere to the forming paper, allowing for easier removal of the attached material from the forming paper. A lateral notch is created in the forming paper to facilitate quick manual separation of the non-adhesive portion.

[0028] This invention achieves a bottom-synchronization effect through a base layer to support the formed paper. For protruding formed paper, filler material one is used for support. By setting the tops of filler material one and filler material two to the same height, a horizontal effect for the attached material is ensured. Furthermore, by attaching the material to a foam-like material, a rapid separation effect can be achieved, thus enabling the rapid separation of the attached material from the formed paper.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Example 1

[0047] Please see Figure 1 and 2 The present invention provides a technical solution: an easy-to-tear release paper, comprising:

[0048] like Figure 1As shown, the formed paper 1 includes a paper layer 11, and a coating layer 12 of the same thickness is provided on the upper and lower surfaces of the paper layer 11. A silicone oil layer 13 is coated on the surface of the coating layer 12 located on the upper surface of the paper layer 11.

[0049] At least two sets of tear lines 4 are provided on the forming paper 1, and the two sets of tear lines 4 intersect at their ends; an adhesive 5 is adhered to the silicone oil layer 13, and one set of tear lines 4 passes through the area covered by the adhesive 5 on the release paper, used to separate the adhesive 5 from the silicone oil layer 13. The silicone oil layer protects the adhesive between the adhesive and the release paper, preventing significant loss.

[0050] The tear lines are created by the equipment, making it easier for users to peel off the label along the lines. The attached material can be labels, plasters, or other items requiring release paper.

[0051] Figure 2 It is a top view of multiple sets of formed paper and the attachments on top, and the attachments are not drawn in the first set in order to show the shape of the formed paper.

[0052] Unlike existing technologies that typically use a single set of tear lines, which only separate the release paper but are ineffective at quickly removing adhering substances, this embodiment employs at least two sets of tear lines, each serving a different function. One set passes through the area where the adhering substance is stuck to the release paper. This method allows for unidirectional tearing of the release paper, achieving rapid separation of the release paper and the adhering substance.

[0053] Example 2

[0054] like Figure 3 As shown, another embodiment of this utility model is provided. Based on embodiment 1, a notch is provided to enhance the rapid separation effect of the tear line.

[0055] The two sets of tear lines 4 include tear line one 41 and tear line two 42, wherein multiple sets of tear line one 41 and tear line two 42 are provided; tear line one 41 is used to separate the front and rear release paper, and tear line two 42 is used to separate the attached material 5 and the release paper.

[0056] Notches 43 are provided at both ends of the tear line 41, and the tear line 41 is connected to the middle of the notch 43; and the notch 43 is located on both sides of the release paper.

[0057] In this embodiment, the second tear line is straight and connected to the surface of the notch.

[0058] When using, through Figure 3The upper notch is torn downwards along the first tear line to separate the next set of forming paper. The tearing direction is from the notch that is not connected to the second tear line to the other set of notches. Then, it is torn along the second tear line to remove part of the release paper on the bottom side of the attached material, thereby revealing the adhesive side of the attached material. This allows the attached material to be quickly removed from the remaining release paper, completing the removal of the attached material.

[0059] One end of the second tear line 42 intersects the first tear line 41 at a set of notches 43. The second tear line 42 can be a straight line, a curve, or a broken line; in this application, the second tear line is a straight line.

[0060] Example 3

[0061] like Figure 4 As shown, this is another embodiment of the present invention. Based on embodiment 2, the tear line 42 is an arc shape within a curve, and as... Figure 4 Set the center of the circle downwards and to the lower left.

[0062] Example 4

[0063] like Figure 5 As shown, another embodiment of the present invention is presented. Based on embodiment 2, the second tear line 42 is zigzag, and the other end of the second tear line 42 intersects with the next set of first tear lines 41.

[0064] Example 5

[0065] like Figure 6 and 7 As shown, this is another embodiment of the present invention. Based on embodiment 2, the attachment 5 includes an adhesive part 51 and a non-adhesive part 52, and multiple attachments 5 are provided; each attachment 5 is located between adjacent tear lines 41.

[0066] A lateral notch 6 is provided on the release paper. The lateral notch 6 is located on one side of the non-adhesive portion 52, and the non-adhesive portion 52 extends above the lateral notch 6. The adhesive portion 51 does not overlap with the lateral notch 6.

[0067] This embodiment adds a non-adhesive portion to the attached material, so that the non-adhesive portion does not stick to the forming paper, making it easier to remove the attached material from the forming paper. A lateral notch is made in the forming paper to facilitate quick manual separation of the non-adhesive portion.

[0068] Example 6

[0069] like Figure 8As shown, another embodiment of the present invention is shown in Embodiment 3. In order to quickly separate the forming paper and the attached material, a reserved side edge 7 is provided on the outside of the forming paper 1. The reserved side edge 7 does not contact the attached material 5.

[0070] The outer side of the reserved side 7 is either a straight line, a curve, or a broken line. In this embodiment, for example... Figure 8 It adopts a wavy shape in the curve, and when in use, by bending and leaving the side, the attached material and the formed paper can be separated relatively quickly.

[0071] Example 7

[0072] like Figure 9 and 10 As shown, this is another embodiment of the present invention. Based on embodiment 1, when the attachment is fully spread on the forming paper, it may not be able to separate quickly through the lateral notch and the tear line 42. A base layer 8 is provided on the side of the forming paper 1 facing away from the attachment 5; the middle of the forming paper 1 protrudes upward; a filler 9 is provided between the forming paper 1 and the base layer 8.

[0073] like Figure 10 As shown, filler material 2 10 is installed on the forming paper 1 on both sides of the protrusion; the top height of filler material 2 10 and filler material 1 is the same. Filler material 2 10 is foam material.

[0074] This invention achieves a bottom-synchronization effect through a base layer to support the formed paper. For protruding formed paper, filler material one is used for support. By setting the tops of filler material one and filler material two to the same height, a horizontal effect for the attached material is ensured. Furthermore, by attaching the material to a foam-like material, a rapid separation effect can be achieved, thus enabling the rapid separation of the attached material from the formed paper.

[0075] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
