Description

Technical Field

[0001] This utility model relates to an edge-sealing tape for packaging large Low-E sheets, belonging to the field of glass packaging technology. Background Technology

[0002] Low-E glass is widely used due to its excellent heat insulation and light transmission properties. To protect Low-E glass from damage during transportation and storage, operators typically cover its surface with packaging panels and secure it with edge-sealing tape. However, in practical applications, especially in high-temperature and high-humidity environments, existing edge-sealing tapes tend to leave adhesive residue on the glass surface when removed, increasing cleaning costs and potentially affecting the glass's optical performance and aesthetics. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model designs an edge-sealing tape for packaging large Low-E glass panels, which greatly improves the residue phenomenon when it is torn off, and avoids subsequent cleaning of the surface of large Low-E glass panels.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A sealing tape for packaging large boards (Low-E) includes a plastic film layer, an adhesive layer is provided on one side of the plastic film layer, and a cut-resistant material layer is provided on the side of the adhesive layer away from the plastic film layer, wherein the width of the cut-resistant material layer is smaller than the width of the adhesive layer.

[0006] The adhesive layer includes a self-adhesive layer and an tackifying layer with a viscosity greater than that of the self-adhesive layer, and the plastic film layer, the tackifying layer, the self-adhesive layer and the cut-resistant material layer are stacked in sequence.

[0007] Furthermore, the thickness of the tackifying layer is H, and the thickness of the self-adhesive layer is h, where H ≥

[0008] 1.3h.

[0009] Furthermore, an anti-sticking paper for covering the adhesive layer is provided at the edge of the plastic film layer.

[0010] Furthermore, the cut-resistant material layer is adhered to the middle of the plastic film layer.

[0011] Furthermore, a metal film layer is deposited on the plastic film layer.

[0012] Compared with the prior art, this utility model has the following features and beneficial effects:

[0013] This invention protects the edges and corners of large-format Low-E glass using a cut-resistant material layer. After peeling off the release liner from the edge of the plastic film layer, the product can be adhered to the Low-E glass, providing effective protection. Simultaneously, by incorporating an adhesive layer with a higher viscosity than the adhesive layer, the product can be peeled off along with the adhesive layer, preventing it from adhering to the Low-E glass surface. This significantly reduces adhesive residue and eliminates the need for subsequent cleaning of the Low-E glass surface. Attached Figure Description

[0019] The present invention will now be described in more detail with reference to the embodiments.

[0020] Example 1

[0021] like Figures 1 to 4 As shown, the edge sealing tape used for Low-E packaging panels in this embodiment includes a plastic film layer 4, which mainly serves to seal, waterproof, and prevent air from entering.

[0022] An adhesive layer is provided on one side of the plastic film layer 4, and a cut-resistant material layer 1 is provided on the side of the adhesive layer away from the plastic film layer 4.

[0023] The cut-resistant material layer 1 is made of non-woven fabric, cotton cloth, fiber cloth or geotextile, which is low in cost and not easily cut by the edge of the large Low-E glass. The plastic film layer 4 works in conjunction with the cut-resistant material layer 1 to protect the large Low-E glass and prevent it from scratching the plastic film layer 4.

[0024] Specifically, please refer to Figure 2 The adhesive layer includes a self-adhesive layer 2 and an tackifying layer 3 with a viscosity greater than that of the self-adhesive layer 2. The plastic film layer 4, the tackifying layer 3, the self-adhesive layer 2, and the cut-resistant material layer 1 are stacked in sequence.

[0025] By setting an adhesive layer 3, which has a higher viscosity than the adhesive layer 2, the adhesive layer 2 can be removed when the product is peeled off, thus preventing the adhesive layer 2 from adhering to the surface of the large Low-E glass. This greatly improves the problem of residual adhesive and avoids the need for subsequent cleaning of the large Low-E glass surface.

[0026] In this embodiment, the 180° peel strength of the adhesive layer 3 is: PS 增粘层 ≥PS 不干胶层 ×1.5.

[0027] In this embodiment, the tackifying layer 3 belongs to the acrylic resin category.

[0028] Furthermore, the thickness of the tackifying layer 3 is H, and the thickness of the self-adhesive layer 2 is h, where H ≥ 1.3h.

[0029] In this embodiment, the width of the cut-resistant material layer 1 is smaller than the width of the plastic film layer 4, and the width of the cut-resistant material layer 1 is smaller than the width of the adhesive layer. When the plastic film layer 4 wraps around the large Low-E glass, it facilitates the adhesion of the adhesive layer to the surface of the large Low-E glass.

[0030] In this embodiment, the cut-resistant material layer 1 is adhered to the middle of the plastic film layer 4.

[0031] Leaving a certain distance at the edge of the plastic film layer 4 allows the adhesive layer to adhere well to the large Low-E glass.

[0032] Please see Figure 3 The edge of the plastic film layer 4 is provided with a release paper 5 for covering the adhesive layer. The release paper 5 can prevent debris or other substances that affect the adhesion from sticking to the adhesive layer that is not covered by the cut-resistant material layer 1. When using, the release paper 5 is torn off, and then the adhesive layer at the edge of the plastic film layer 4 is to be pasted onto the surface of the large Low-E glass.

[0033] For ease of use, the following is adopted: Figure 4 The packaging shown has the adhesive layer rolled inwards onto a cylinder, and the appropriate length can be cut as needed when taking it out.

[0034] Furthermore, a metal film layer is coated on the plastic film layer 4. The plastic film layer 4 coated with the metal film layer has excellent folding resistance and good toughness, rarely has pinholes and cracks, and does not exhibit bending or cracking phenomena. Therefore, it has good barrier properties against gases, water vapor, odors, light, etc.

[0035] Among them, the metal thin film layer is preferably an aluminum thin film layer.

[0036] In this embodiment, the material was adhered to the surface of a large Low-E glass panel in an environment with a temperature of 35°C and a humidity of 80%. The initial peel force was 58.68 N / 25 mm, and no adhesive residue was left after peeling.

[0037] Example 2

[0038] This embodiment is a comparative embodiment. The difference between this embodiment and the first embodiment is that the sealing tape in this embodiment includes a plastic film layer 4, an adhesive layer 2 and a cut-resistant material layer 1 stacked in sequence.

[0039] In this embodiment, the adhesive was adhered to the surface of a large Low-E glass panel in an environment with a temperature of 35°C and a humidity of 80%. The initial peel force was 51.23 N / 25 mm, and the adhesive residue was clearly visible to the naked eye after peeling.

[0040] The comparison shows that after adding the tackifying layer 3 in Example 1, the initial peel force was increased by 14.5%, and the residual adhesive phenomenon was greatly improved.

[0041] The working principle of this utility model is as follows: By attaching the cut-resistant material layer 1 to the corners of the large Low-E glass, the corners of the large Low-E glass can be protected. The cut-resistant material layer 1 covers all the corners of the large Low-E glass, and the excess part is bent and attached to the surface of the large Low-E glass. At this time, the release paper 5 at the edge of the plastic film layer 4 can be peeled off, and the product can be pasted onto the large Low-E glass to complete the effective protection of the large Low-E glass.

[0042] When the packaging is removed, the adhesive layer 3, which has a higher viscosity than the self-adhesive layer 2, can be removed, thus preventing the self-adhesive layer 2 from adhering to the surface of the large Low-E glass. This greatly improves the problem of residual adhesive and avoids the need for subsequent cleaning of the large Low-E glass surface.
