Description

Technical Field

[0001] The utility model relates to the technical field of precision die-cut products, in particular to a die-cut product comprising a padding strip. Background Art

[0002] Many die-cut products are made of soft materials and are prone to deformation during storage and transportation. Conventional solutions involve delivering products to customers immediately after production, before they deform, or by adding extra material to the sides of the product to extend and reduce the pressure on the product during storage and transportation. However, if the spacer bars themselves deform or shift, their pressure-bearing function will be compromised, rendering them ineffective in protecting the product. Furthermore, existing spacer bars are inconvenient to use. Summary of the Invention

[0003] The purpose of the present invention is to address the above-mentioned deficiencies in the prior art and to provide an easily deformable die-cut product with a padding strip to solve the problem that the die-cut main material is compressed and deformed by the adsorption force between the protective layers or external forces during transportation or storage.

[0004] The technical solution adopted by the present invention is: a die-cut product including a padding strip, the die-cut product at least includes a soft main material and protective layers attached to its upper and lower surfaces; wherein, a padding strip is further provided between the upper and lower protective layers, and the padding strip is arranged between adjacent soft main materials, and the thickness of the padding strip is not less than the thickness of the soft main material.

[0005] The distance between the raising strip and the adjacent soft main material should not be greater than 1.5mm, and 1mm-1.5mm is more appropriate. Too far a distance will affect the raising and supporting effects.

[0006] The soft main material is in a circular shape, and the thickness of the circular soft main material is greater than its ring width; the distance between the raising strip and the adjacent soft main material is 1mm-1.5mm, and the difference between the thickness of the raising strip and the thickness of the soft main material is 0.05mm-0.5mm, preferably 0.15mm.

[0007] Preferably, the tensile strength of the raising strip is greater than or equal to 160 Mpa.

[0008] Preferably, of the two surfaces of the raising strip in contact with the upper and lower protective films, one surface is an adhesive surface and the other surface is an anti-adhesive surface.

[0009] The heightening strip is formed by composite die-cutting of a PET release film and a double-sided adhesive layer attached to a non-release surface of the PET release film.

[0010] Preferably, the peeling strength of the adhesive surface of the raising strip is greater than or equal to 3.2 N / cm.

[0011] Preferably, the anti-adhesive surface peeling force of the raising strip is less than or equal to 49 mN / 25 mm.

[0012] The utility model is beneficial for reducing the probability of deformation of the main material product due to pressure in the soft main material die-cut product with the padding strip, thereby improving the product yield; in addition, the padding strip itself has a sticky surface and a non-sticky surface, which can not only maintain its own position stable and avoid contact with the main material and displacement of the main material, but also has good removability, which brings convenience to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 、 Figure 2 They are respectively schematic diagrams of decomposition and assembly of the utility model for a die-cut product in an embodiment. DETAILED DESCRIPTION

[0014] like Figure 1-Figure 2 As shown, the utility model describes a die-cut product including a padding strip, and the die-cut product includes at least a soft main material 1 and protective layers attached to its upper and lower surfaces. In this embodiment, the protective layers are an upper release film 2 and a lower release film 3; the soft main material 1 is a circular hot melt adhesive, and its thickness is 0.3mm, and its ring width is 0.25mm, that is, the thickness is greater than the ring width, so it is easy to deform, and the lower release film 3 is also formed with a through hole 31 corresponding to the inner ring of the annular soft main material 1; in this embodiment, the padding strip 4 is also arranged between the upper and lower protective layers, namely the upper release film 2 and the lower release film 3 and is located between adjacent soft main materials 1, which plays the role of isolating and supporting the upper release film 2 and the lower release film 3, and the thickness of the padding strip 4 is not less than the thickness of the soft main material 1. Of the two surfaces of the raising strip 4 that contact the upper and lower protective films, one is a sticky surface and the other is an anti-sticky surface; in this embodiment, the raising strip 4 is die-cut from a PET release film 41, and its release surface serves as the anti-sticky surface, which is compounded with the lower release film 3 facing downward, while the non-release surface is compounded with a double-sided adhesive layer 42, and the sticky surface of the raising strip 4 is compounded with the upper release film 2, thereby forming a die-cut product containing a raising layer 4.

[0015] During the production of the die-cut product of this embodiment, the hot-melt adhesive layer is compounded with the lower release film and then die-cut and discarded to form a ring-shaped soft main material 1 and a lower release film with holes, which is a semi-finished product A. The PET release film is then compounded with the double-sided adhesive layer and die-cut into strips, and then compounded with the upper release film at equal intervals through the double-sided adhesive layer to form a semi-finished product B; the semi-finished product A and the semi-finished product B can then be aligned and combined.

[0016] The distance between the raising strip 4 and the adjacent soft main material 1 is not greater than 1.5 mm, and 1 mm to 1.5 mm is more appropriate. Too far a distance will affect the raising and supporting effects.

[0017] The difference between the thickness of the raising strip 4 and the thickness of the soft main material is 0.05mm-0.5mm, that is, the thickness difference does not need to be too large, otherwise the protective film will easily separate from the main material, affecting the protective effect of the protective film on the main material; in this embodiment, the thickness of the PET release film 41 of the raising strip 4 is 0.2mm, the thickness of the double-sided adhesive layer 42 is 0.15mm, and the overall thickness of the raising strip 4 is 0.35mm, which is 0.05mm higher than the thickness of the hot melt adhesive of the soft main material 1 of 0.3mm.

[0018] Preferably, the tensile strength of the raising strip 4 is greater than or equal to 160 Mpa, and it has strong resistance to compression and tension, so as to achieve an ideal supporting effect; the peeling strength of the adhesive surface of the raising strip 4 is greater than or equal to 3.2 N / cm, so as to fix the position of the raising strip 4 itself to avoid displacement and contact with the soft main material 1; the peeling force of the anti-adhesive surface of the raising strip 4 is less than or equal to 49 mN / 25 mm, so that the raising strip 4 as a whole has better removability and is easy to use.

[0019] In summary, the padding strip of the utility model is used in die-cut products of soft main materials, which is beneficial to reduce the probability of deformation of the main material products due to pressure and improve the yield of the products; in addition, the padding strip itself has a sticky surface and a non-sticky surface, which can not only maintain its own position stable and avoid contact with the main material and displacement of the main material, but also has good removability, which brings convenience to use.

[0020] The above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, but the present invention is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and essence of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
