In a further embodiment, core 40 can include one or more core layers in addition to the core layer based on foam. For example, in a particular embodiment and as illustrated in figure 3, core 40 can be included containing the core based on foam First core layer 46 and the second core layer 47 containing the core layer based on film of layer.In addition, as illustrated in figure 4, core The heart can include the first core layer 48 containing the core layer based on foam and the second core layer 49 containing the core layer based on film, Wherein the first core layer 48 and the second core layer 49 are separated by the 3rd adhesive 50.It should be understood that in the model of the application In enclosing, can using than in Fig. 3 and 4 it is illustrated it is less, in addition or different layers or sequence of layer, and Fig. 3 and 4 The adhesive tape of middle diagram is exemplary embodiment.

In a particular embodiment, the core layer based on film can include polyurethane film, polyethylene film, polyolefin film, poly- third Alkene film or its combination.In the specific embodiment of pole, the core layer based on film can include polyurethane film.

Core layer described herein each with gluing oxidant layer identical direction as described above on measure Given thickness.In certain embodiments, the core layer based on foam is typically with the thickness more than the core layer based on film. For example, can be at least about 0.05mm, at least about 0.08mm or even based on the thickness of the core layer of foam At least about 0.1mm.In a further embodiment, based on the thickness of the core layer of foam can be no more than about 2.5mm, No more than about 2mm, no more than about 1.5mm or even less than about 1.3mm.Additionally, in a particular embodiment, Thickness based on the core layer of foam can be in the range of any one of minimum of a value provided above and maximum, such as In about 0.08mm to about 2mm, or or even about 0.1mm to about 1.5mm in the range of.

In a further embodiment, the thickness based on the core layer of film can be in the range of about 0.005mm to about 1mm.

In a particular embodiment, for example when core contains the core layer based on foam and the core layer based on film, based on film Core layer can be with the thickness less than the core layer based on foam.For example, in a particular embodiment, foam core The thickness ratio of central layer and film core layer can be about 1:0.01 to about 1:In the range of 0.99.

In certain embodiments, core 40 can be with the elongation measured according to ASTM D412.For example, exist In specific embodiment, the elongation of core 40 can be at least about 200%, at least about 300%, at least about 400%, extremely Few about 500% or even at least about 600%.In a further embodiment, the elongation of core 40 can be no more than About 2500%, no more than about 2200%, no more than about 2000%, no more than about 1800% or even less than about 1700%.

The concrete advantage of the application some embodiments is whole using at least one core layer with the elongation and core Body is helping to be derived from least one component that adhesive tape is adhered to and in certain embodiments after initially-separate component The removing substantially free of residue of two components.For example, the elongation of the first core layer and the second core layer can be with The surface of the component that be enough to allow core layer (and gluing oxidant layer or film layer of any attachment) to be adhered to relative to which is to be less than 35 degree of angle stretching, and core layer and gluing oxidant layer unsticking knot are made, while adhesive is not substantially left on component Residue.What such construction herein referred to as " can also be stretched removable ".

As illustrated in fig. 5, the first gluing oxidant layer can adhere to first assembly and the second gluing oxidant layer can be adhered to Second component.As illustrated in figure 6, first assembly 60 can be separated with the second component 62.Due between core layer Adhesive strength is relatively low so that in the first gluing oxidant layer 20 and the second gluing oxidant layer 30 and first assembly 60 and the second component Before 62 separate, the first core layer 42 is separated with the second core layer 43.As illustrated in fig. 7, the first core layer 42 With the first gluing oxidant layer 20 can be adapted to from the surface of first assembly 60 be no more than about 35 degree angle stretch with Remove the first core layer 42 and the first gluing oxidant layer 20 so that first assembly 60 is substantially free of after the stretch from The adhesive residue of one gluing oxidant layer.

Similarly, in further embodiment (not shown), the second core layer and the second gluing oxidant layer can be adapted to certainly The surface of the second component is stretched with the angle for being no more than about 35 degree to remove the second core layer and the second gluing oxidant layer so that Second component is substantially free of the adhesive residue from the second gluing oxidant layer after the stretch.

In a particular embodiment, core layer can contain the first core layer and with substantially the same with first core layer The second core layer of composition.For example, referring to Fig. 1, the first core layer 42 and the second core layer 43 can be bases In the core layer of foam, and can be the core layer based on polyurethane foam in addition.

In other embodiments, core can be containing the first core formed but taken a different form by substantially the same polymer Central layer.For example, referring to Fig. 3, the first core layer 46 can be containing the layer based on foam, and the second core layer 47 can be containing by the layer based on film formed with the layer identical raw polymer based on foam.It is concrete as one Example, the first core layer can be polyurethane foams, and the second core layer can be polyurethane film.

In the other embodiments, core layer can be containing by forming with the different types of raw polymer of the second core layer again First core layer.For example, referring to Fig. 4, the first core layer 48 can be the layer and the second core layer based on foam 49 can be layer as described above based on film.In addition, referring to Fig. 2, the first core layer 44 and the second core layer 45 can be the layer based on foam, but the first core layer can have different types of raw polymer.For example, First core layer can be the layer based on polyurethane foam, and the second core layer can be the layer based on polyethylene.

The overall thickness of adhesive tape can be the outer surface measuring from the outer surface of the first gluing oxidant layer to the second gluing oxidant layer.Lift For example, in a particular embodiment, the overall thickness of adhesive tape can be at least about 0.1mm, at least about 0.18mm or very To being at least about 0.2mm.In a further embodiment, the gross thickness of adhesive tape can be no more than about 8mm, be less than About 6mm, no more than about 5mm or even less than about 4.2mm.Additionally, the gross thickness of adhesive tape can be carried more than For minimum of a value and any one of maximum in the range of, such as in about 0.1mm to about 5mm, or or even about 0.1mm To in the range of about 4.2mm.

As discussed herein, in certain embodiments, when two components that separation adheres to each other via adhesive tape, glue Band can be adapted to peel off inside Jing, for example, peel off in core.For example, when by adhesive tape from relative first type surface During separation, adhesive tape can be adapted to the interface between the first core layer and the second core layer and peel off.

In certain embodiments, in order to help target location is peeled off during separating, core layer can have specific bonding Intensity.For example, the adhesion strength between the first core layer and the second core layer can be less than the glue of the first gluing oxidant layer Viscous intensity.In addition, the adhesion strength between the first core layer and the second core layer can be less than the gluing of the second gluing oxidant layer Intensity.Again in addition, the adhesion strength between the first core layer and the second core layer can be less than the gluing of the first gluing oxidant layer Intensity and the adhesive strength less than the second gluing oxidant layer.
