BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a security tape, and more particularly, to a tape for easily confirming whether a tape has been peeled off from a security bag or a sealing object.

When storing documents or items that require security, put them in an envelope and seal them with tape. In addition, in order to prevent the operation of the object, which can capture and / or store security contents such as a camera, a notebook, and a mobile phone, the camera lens or the notebook mobile phone is sealed with tape so as not to be opened and / or operated.

At this time, after trying to secretly view the contents of the document, remove the sealed tape, check the contents of the document, or remove the sealed tape to operate the device such as a camera notebook mobile phone, operate the devices, Can be put as original.

Therefore, it is important to be able to easily check whether the contents of the envelope have been read by someone, or whether a device such as a camera or a notebook has been used without permission. Therefore, a tape is needed to easily identify whether the sealing or sealing tape is peeled off and reattached.

Korea Publication No. KR10-2010-0066260 (June 17, 2010)

Accordingly, an object of the present invention is to provide an apparatus and a method for sealing an object to be secured, such as an envelope, a portable device having a camera function such as a mobile phone or a tablet PC, To provide a tape that can be used.

In order to achieve the above object, the tape of the present invention comprises a film layer, a first adhesive layer formed on the film layer, a printing layer formed on the first adhesive layer, and a second adhesive layer formed on the printing layer, And a second adhesive layer, wherein the printing layer is subjected to a releasing process between a portion of the printed character or figure and another portion, and when the tape is detached after being attached to the mounting object, Shaped portion is displayed.

Further, by controlling the adhesive force between the first adhesive layer and the second adhesive layer of the tape of the present invention, when the tape is peeled off from the object to be adhered, a portion of the printed layer adhered to the second adhesive layer is not left or remained .

The adhesive strength (gf / in) of the second adhesive layer of the tape may be in the range of 650 to 750 gf / in as a residual type or 200 to 300 gf / in as a non-residual type, And a release process is performed.

Further, the tape of the present invention is characterized in that a coating layer is further formed on the film layer and wound in a roll form.

When the tape of the present invention is once attached, it is easy to see that the tape is remounted again after it is detached and reattached to the original state.

The tape of the present invention can be used for sealing important security documents or envelopes, and can also be used in a variety of places where it is necessary to easily check whether the sealing of a camera notebook phone or the like is arbitrarily released.

Further, the surface contacting with the adhesive layer is treated in a special manner to form a roll rather than a tape of a single item, which is economically more effective.

Therefore, the tape of the present invention has advantages when a military facility or an article requiring security is used for security.

Figures 5 (a) -5 (d) illustrate embodiments of a security envelope using a tape according to the present invention.

The tape of the present invention is a security tape which can be easily checked once the tape is peeled off. When the tape is sealed, only the state of the tape can be confirmed later so that it can be easily confirmed that someone has worn the tape.

To this end, in the present invention, a predetermined character or symbol is printed on the adhesive layer, and the tape is produced by varying the adhesive strength and tensile strength of the adhesive layer of the tape within a predetermined range. Therefore, once the tape is attached to a predetermined area, the adhesive strength of the adhesive layer is different, and the printed characters or symbols of the tape on the separated part are deformed. So that it can be left.

Hereinafter, the tape of the present invention will be described in more detail with reference to the drawings. 1 is a sectional view showing a schematic layer structure of a tape according to the present invention. The tape 100 of the present invention mainly comprises a coating layer 10, a film layer 20, a first adhesive layer 31, a printing layer 40 including a stationery or drawing, and a second adhesive layer 32 have.

The tape 10 of the present invention is laminated in the order of the coating layer 10, the film layer 20, the first adhesive layer 31, the printing layer 40, and the second adhesive layer 32, The layer used for the tape can be used.

First, the coating layer 10 is coated with a transparent resin or the like to protect the tape. The coating layer 10 plays an important role in making a roll-shaped tape described later, and may be omitted if it is not in the form of a roll.

The film layer 20 on which the coating layer 10 is coated may be a base layer serving as a support, and various resin layers may be used. The film layer 20 serves to maintain mechanical strength and to support the underlying layers. Therefore, a variety of polymeric resin films can be used, and a transparent film layer or transparent impermeable layer or semitransparent layer that can be identified as opaque or non-opaque characters or figures can be used to identify the underlying print layer Is preferably used. For example, one or more of polyethylene, polypropylene, polyvinyl chloride, polyethylene naphthalate, polyethylene terephthalate, polycarbonate, and the like.

The first adhesive layer 31 is formed under the film layer 20, and general adhesives can be used. A printed layer 40 is formed under the first adhesive layer 31. A desired image or phrase can be created on this print layer, and in particular a security mark or warning phrase can be printed. A second adhesive layer 32 is formed under the print layer 40 so that the tape 100 of the present invention can be attached to an object. The tape 100 of the present invention may be made as a single tape, for example, as a band-like tape, or may be made in the form of a roll-shaped tape as shown in Fig.

The tape of the present invention is characterized in that traces are left on the printed layer when the tape 100 is removed and reattached. For this purpose, the first adhesive layer 31 and the second adhesive layer 32 have different adhesive forces. That is, when the second adhesive layer 32 is formed by differently processing the characters to be printed or the remaining part of the figure, the characters of the print layer 40 Since the characters or figures of the print layer 40 are separately attached to the adhesive layers on both sides separately from the other portions subjected to the differently shaped processing, the printed patterns 40 are separated and adhered to the first adhesive layer 31 and the second adhesive layer 32, And a trail is left.

Further, the print layer 40 between the adhesive layers may have a warning sign such as " prohibition of opening " in the print layer so as not to be visible in a tape state, and may be visible depending on the difference in adhesive force between the two adhesive layers when the tape is peeled off. . The printing layer 40 may be formed as a single layer, and may be formed as a multi-layer print layer, if necessary. For this purpose, the printing layer may be formed in a manner to be applied a plurality of times. First, the entire surface is formed thin, and then the letter portions or the like can be applied to the layers. Depending on the state of the adhesive layer on which the print layer is formed, if the letters are strongly adhered to the surface, strong portions remain on the surface, and the weak portions are left on the opposite side. This will allow the traces of letters to remain on the attachment surface.

2 is a perspective view and a cross-sectional view showing that the tape of the present invention is wound in a roll state. As shown in FIG. 2, the roll-shaped tape 200 is formed as a four-layer structure as shown in FIG. 1, and in particular, the coating layer 10 can serve as a protective film, .

Unlike ordinary security tapes, when used as a roll type, traces appearing on the upper layer appear before use, making it difficult to manufacture with a roll-type security tape, so that it is manufactured in a simple sticker style according to the size of use. The security type roll tape 200 according to the present invention exhibits traces of adhesive strength when it is attached, and is wound in a roll shape so that the size thereof can be cut and used as needed. When the second adhesive layer 32 is formed of an acrylic adhesive material, when the surface of the object to be adhered is left unremoved, the surface adhesion force is set in the range of 17 to 20% It is possible to prevent discomfort when attaching the security tape.

When the adhesive force of the surface is made into a roll tape type, existing security tapes are difficult to be produced in a roll shape because the traces of the existing security tapes appear on the surface due to mutual adhesion surfaces. However, the tape of the present invention prevents the traces from falling off even if they are mutually adhered to each other due to the characteristics of the coating layer 10 treated on the surface of the film layer 20.

In addition, the security tape of the present invention can be classified into a residual type in which traces are left on the object when the object is removed, and a non-residual type in which there is no trace when the object is removed.

FIGS. 3 and 4 are perspective views showing that the tape of the present invention is stuck to an object and that the traces remain when the object is attached and removed, and FIGS. 4A and 4B are perspective views showing that no trace is left when the object is attached and detached.

There are differences in the manufacturing method between the residual type and the non-residual type,

As in the embodiment of FIG. 3, the remaining type tape 110 may be formed by coating a releasing agent on a residual portion as shown in FIG. 3 so that the releasing force is different, or when the pressure-sensitive adhesive for coating the second adhesive layer 32 is coated, Or the thickness of the coating is different from that of the first adhesive layer 31 or the adhesive force of the second adhesive layer 32 remaining on the object and the adhesive strength of the first adhesive layer 31 of the tape portion are made the same, 32 can be formed in advance. That is, the second adhesive layer 32 is formed or the adhesive strength of the first adhesive layer 31 is weakened by subjecting the print layer 40 to a predetermined character or graphic pattern, 32) can be left behind. As shown in FIG. 3, when the tape 110 is attached and peeled off, the printed portion of the print layer 40, which is contained in the print layer 40, The phrase "prohibition of opening" is left on the object. 3, the left side shows the state in which the tape is dropped and the first adhesive layer remains on the object together with the red "unsealing" character. The thick black characters "black" and "forbidden" on the right side are the portions where the tape of the present invention is shown before use, the red color is the entire printed layer 40, and the characters are arbitrarily inserted. The black "unsealing" bold characters are used arbitrarily, indicating that the tape of the present invention is a tape forbidden to be opened, and preferably formed between the film layer 20 and the coating layer 10 of FIG. So that the coating layer 10 can take advantage of its use as a roll. If the coating layer 10 is not used, it may be printed on the film layer 20 only.

The red print layer 40 is separated from the first adhesive layer 31 and the second adhesive layer 32 so that when the tape 110 is separated from the object, the print layer 40 is separated, Let the characters remain. Conversely, the red character portion may remain in the first adhesive layer 31 and the second adhesive layer 32 may display the character in the empty space portion. So that characters and shapes corresponding to the portion subjected to the release processing can be left. In the residual type, the printing layer may be made of a transparent layer, but it can be made into a layer of various colors or shades, and it is preferable to have a color so that it can be seen clearly since the layer is separated and separated.

As in the embodiment of Fig. 4, the non-residual type tape 120 also performs a releasing process on a falling portion (for example, a warning character portion) of the print layer. In the non-residual type, any component, such as a character or figure portion and a second adhesive layer, which have been subjected to release treatment remain on the tape and remain on the tape, It is important to lower the releasing force and adjust the thickness of the coating when the pressure-sensitive adhesive is coated so that the release character of the printing layer, such as prohibition of opening, does not go over to the object. That is, when the tape is separated from the object to be adhered, the release-processed printed portion of the print layer is separated into the first adhesive layer and the second adhesive layer, respectively, and the second adhesive layer and the printing layer adhered to the second adhesive layer, The part remains on the tape without being left on the object.

Thus, when the adhesive force (gf / in) of the second adhesive layer 32 is set to 650 to 750 gf / in for the residual type and to 200 to 300 gf / in for the non-residual type, Can be made.

The printing layer of the present invention can be additionally implemented by other methods other than the above description. The print layer may be separated into a multi-layer structure, and the color and the letter may be different from each other. For this purpose, the upper and lower basic print layers are added in place of the adhesive layers so that the colors are preliminarily colored in the lower print layer as in the case of printing a monolayer print layer between upper and lower adhesive layers as described above, If you make a character or figure, you can make different colors and letters appear before and after you take off the tape. The printing layer may be formed of two or more layers so that a basic color and letters or figures before use of the tape are displayed on the upper layer, and letters, figures and the like as in the above single printing layer are subjected to a releasing process. Further, a lower layer may be further formed to form a printing layer as three layers, and a color such as a letter or the like according to the release process may be formed in the lower layer when the tape is peeled off. That is, the upper print layer and the lower print layer are divided and divided, and the upper surface of the lower print layer includes the color and color appearing when the tape is peeled off. When attaching the tape, the color and the characters of the upper surface of the print layer are visible. When the tape is attached and removed, the characters and figures of the upper and middle print portions of the print layers of the multi- And the other release treated portion of the intermediate printed portion and the lower printed layer may be adhered to the second adhesive layer.

Here, the adhesive layer may contain a colorant so that the adhesive layer looks like a color when the tape is peeled off. The adhesive layers of the present invention may have a basic color including a desired color so that the characters or graphics shown in the print layer can be displayed by using the color of the adhesive as a color when the tape is peeled off.

The tape according to the present invention can be used in a security envelope in which a security device can not be photographed by preventing a portable device having a camera function such as a cell phone or a tablet from being photographed when photographing with a lens of a camera such as a smart phone, have. That is, as an example of such a security envelope, a transparent portion is formed so that shooting can be prevented while allowing the user to visually confirm a smart phone or the like, which is an internal storage item, on one surface. The transparent part of the envelope of the present invention is specially processed unlike the general transparent part, so that the naked eye identification is possible, but the camera including the moving picture can not be photographed.

5A to 5D, the security envelope 500 includes a transparent portion 510, and the security envelope 500 may include any one of the tapes 100, 200, 110, 120).

The security envelope may be of a size that can store a portable device having a camera function such as a cell phone or a tablet. Therefore, the upper limit of the size is not particularly limited and sufficient portability is sufficient. The material other than the transparent portion is not particularly limited as long as it is made of an opaque material. Any kind of paper or plastic bag can be used without restriction.

The security envelope (500) is made by forming a transparent portion (510) that can see the inside of all kinds of opaque envelopes that can completely seal an object to be stored such as a smart phone (500) Is a special window that can be seen inside but can not be photographed by the camera from the inside.

It is possible to easily identify a trace when the tape is detached as one of the tapes 100, 200, 110, and 120 of the present invention to the security envelope 500. For the sake of explanation, the representative tape 100 will be described below in Fig.

It is preferable that the transparent portion 510 has a window in the range of the brightness of 6 to 10 candelas and the haze of 1 to 2%, preferably 1.4 to 1.8%. For this purpose, it is preferable to use a transparent film. Also, it is better to have some bending or elasticity to operate a smart phone, so a flexible film is preferable to a rigid material such as glass. The transparent part means a transparent part made by performing a HOLO process on one side of a general transparent part such as a transparent film or a transparent glass. Here, the term "holographic processing" refers to silver deposition in a general hologram design. Preferably, the transparent part is made of holo processing / PET / printing (color 5 degrees) / PE material. The transparent part made in this way can check the contents with the naked eye, but it is difficult to confirm the shape when shooting the outside with the camera. The total thickness of the transparent portion here is about 50-80 microns, preferably about 60 microns, and the thickness of PET and PE is preferably about 90-99%. The printing here is not necessarily necessary and can be selectively used because it can interfere with security phrases and photographing. Therefore, it can be manufactured with holo treatment / PET / PE material.

The hologram used for the holographic processing can dissolve the thermosetting resin so as to soften it and produce a hologram with the pressure. However, rather than coating with a thermosetting resin, it is possible to coat the hologram by coating UV resin first and then curing with light. This causes the optical image to be invisible when shooting with the camera due to the prism effect that appears in each direction for each SHELL. In addition, the technical after-image treatment of the UV coating maximizes the prism effect, which makes the judgment of objects blurred.

A preferable holographic film (UV PET film) as a transparent part is a film using a kind of visual effect (prism) which is recorded by recording interference effect of light on a recording medium. The transparent part applied to this security envelope, such as applied to the field of video technology and industrial packaging, is applied to PET film using UV resin.

That is, the surface of the film is UV coated to enhance the heat resistance and the abrasion resistance, and to impregnate a predetermined design pattern on the coating surface. It is preferable to add a special coating to further blur the image thereafter, which makes it more difficult to shoot the camera. A design pattern is a kind of micro pattern that makes use of the refraction effect of light to form and form a pattern so that the visible side and the non-visible side are displayed simultaneously on one side. When a bar having a thickness of about 50 microns is formed in each cell in a different direction per cell, a plurality of images may be seen when taking a picture. At this time, security phrases such as prohibition of shooting can be inserted between the layers of the film to be applied to the background.

An example of how to make the security envelope will be described below.

First, a PET film having a predetermined thickness of several tens of micrometers is subjected to the above-described HOLO process. Thereafter, printing is performed at about 5 degrees, gravure printing is preferable. Then, dry laminate (laminate) is carried out again on tens of micro-thick PE. Thus, a transparent part film (fabric) is produced.

The transparency film thus formed is cut to an appropriate size and bonded to another fabric (paper or film) of the opaque material of the envelope to form a security envelope.

Finally, the security envelope can be used in a state that a storage object such as a smart phone is received and the tape of the present invention is attached and sealed.

5B is a perspective view illustrating a state in which the tape 100 is attached to the entire top opening surface of the security envelope 500. The security envelope shown in FIGS. 5B to 5D is another embodiment of the security envelope according to FIG. 5A, And the security envelope 500 of FIG. 5 (c) illustrates a security envelope that heats the covering portion of the envelope, such as the security envelope of FIG. 5 (a), and only partially seals with the tape 100.

The security envelope of FIG. 5 (d) shows that the entire envelope is made of transparent material 510. It is possible to put the object to be stored in the envelope and seal the tape 100 as a sealing tape. In other words, the security envelope is sufficient if the transparent portion 510 is larger than a predetermined size, and the entire envelope can be made of a transparent film material.
