As shown in Figure 1, it is a double-sided adhesive tape 1 without a substrate in the past, which includes an adhesive layer 11 made of a strong adhesive, and a release paper attached to the surface of the adhesive layer 11 (not shown in the figure). ), during use, the release paper on one side of the adhesive layer 11 is removed first, and after the adhesive layer 11 is pasted on the surface of the object 13, the release paper on the other side of the adhesive layer 11 is removed to make the object 13 The adhesive layer 11 is exposed on the surface, so that the object 13 can be pasted on the wall surface 14 .

As shown in Figure 2, it is a conventional double-sided adhesive tape 2 with a foam substrate, which includes a foam sheet 21, adhesive layers 22, 23 coated on both sides of the foam sheet 21, and attached to the foam sheet 21 respectively. The release paper on the surface of the two adhesive layers 22 and 23 (not shown in the figure) is used to remove the release paper on the surface of the adhesive layer 22 and attach the adhesive layer 22 to the surface of the object 24. , and then remove the release paper on the surface of the adhesive layer 23, so that the object 24 can be attached to the wall surface 25 through the adhesive layer 23.

The main purpose of the above two double-sided tapes is to make an object closely attached to other objects through the adhesive layer, because the adhesive layer is generally composed of an adhesive with strong adhesive strength, so when the user intends to When the object is removed from the wall, the adhesive strength of the adhesive layer is often too strong, causing the object to be damaged when peeled off, and even the damaged part will remain on the wall together with the foam sheet, resulting in the disadvantage of being difficult to remove In addition, if the wall surface is pasted with wallpaper or has been powdered and smoothed, the peeling of the object will also cause the paint to peel off, which will affect the appearance of the wall surface and is not easy to restore.

The purpose of the utility model is to provide a double-sided adhesive tape that can be peeled off and pasted again, which is convenient to use.

The peelable and sticky double-sided tape of the present invention comprises a core and a release paper attached to the core, the core is coated with an adhesive on both sides, and is characterized in that:

The adhesives on both sides of the core form adhesive layers with different thicknesses, and the adhesives are peelable adhesives. The adhesive strength of the thicker side of the adhesive layer is greater than that of the thinner side, so that different adhesive layers can be pasted separately. Attached to the wall and used for sticking objects, and with the characteristics of repeated peeling and sticking of the peelable adhesive, the objects or double-sided tape can be repeatedly peeled and sticked, and at the same time, it can have the effect of not damaging the wall and the surface of the object .

The utility model has the advantages that: the two sides of the core of the double-sided adhesive tape are coated with an adhesive that can be peeled off to form adhesive layers with different thicknesses and different adhesive strengths. In addition to sticking objects, the double-sided tape can also be repeatedly peeled off and then pasted on other parts of the wall for use without damaging the wall and the surface of the object.

As shown in FIG. 3 , the peelable and reattachable double-sided tape 3 of the present invention includes a core 31 and a release paper 32 attached to the core 31 .

The core 31 can be paper or various plastic layers such as polyethylene (PE; polyethylene), polyvinyl chloride (PVC; polyvinyl chloride), or rubber materials, or foaming materials such as foam, and the core 31 It is formed by elastic or soft material and appropriate thickness, and adhesives are coated on both sides of the core 31 to form adhesive layers 312, 313 with different thicknesses respectively. The adhesive can use a peelable adhesive, its It is composed of a glue containing elastic polymeric microspheres or microparticles. The peelable glue is easy to tear off and can be used repeatedly. In addition, there are many other adhesives that can also be used. Here No more detailed description, but the composition of the peelable adhesive is the same as the prior art, and it is not a feature of the present invention, so it will not be described in detail, the adhesive strength of the thicker adhesive layer 312 is greater than that of the thinner adhesive layer 313 adhesive strength.

As shown in Figure 4, when sticking, because the two sides of the core 31 are coated with peelable glue, so when the peelable glue is under pressure, it can form a proper shape with the attached object (such as wall 34 or object 33, etc.). Because of the different bonding strengths between the core 31 and the wall surface 34 or the object 33, the thicknesses of the peelable adhesive applied on both sides of the core 31 are different, so as to form adhesive layers 312, 313 with different adhesive strengths. That is to say, the thicker adhesive layer 312 is effectively attached to the wall surface 34, or the core 31 can be repeatedly pasted or torn off and moved to another place for attachment, so it has the effect of being easy to use, while the thinner The adhesive layer 313 is exposed to the outside for posting notices on the articles. In addition, the adhesive layer 312 can be firmly in contact with the uneven wall surface 34 through the assistance of the elastic or soft core 31 having an appropriate thickness. , thereby producing a stronger adhesive effect. In particular, when the object 33 is to be firmly bonded to the wall surface 34, the weight of the object 33 must be supported, so that the use area of the double-sided adhesive tape 3 can be increased in due course.
