Description

  The present invention relates to a pressure-sensitive adhesive tape that can be used for packaging, sealing, and the like by being attached to a cardboard box for delivery, envelope, or wrapping paper.

  Conventionally, there are various types of adhesive tape, such as cloth, craft paper, resin film, etc., which are used for packaging and sealing, etc., pasted on cardboard boxes for delivery, envelopes and wrapping paper. The back surface of the base material is a glue surface with strong adhesive strength, while the surface of the base material is a material that can be easily peeled off from the glue surface. Since the pressure-sensitive adhesive tape is stored in the form of a roll, when using it, it is necessary to look for the end of the roll-shaped pressure-sensitive adhesive tape.

  Also, after sticking adhesive tape on cardboard etc. and using it for packaging, it is difficult to peel it off with fingers when disassembling, so it is opened by cutting with a cutter etc., and the sticking adhesive tape piece remains attached It often becomes a state.

  In response to these problems, the tip of the cut adhesive tape is rolled into a loop and the adhesive surfaces are bonded to each other with a certain length to form a tab for the next cutting tape that does not stick to the hand. Techniques for tab forming tape cutters and tab dispensers are known (for example, see Patent Document 1). Although there are some stickers and stickers that have been glued to make a part of the adhesive surface non-adhesive by sticking paper or film to the part of the adhesive surface or by dusting it, as far as the applicant knows with adhesive tape There is no. The kraft tape for packaging and wrapping is older than the adhesive tape, and there is a “gum tape” in which water-soluble gum arabic is applied to the entire surface as a paste like a postage stamp. The gum tape does not have silicon processing on the surface. Generally, an adhesive tape is sometimes called a gum tape, but in the tape industry, a gum tape and an adhesive tape are distinguished from each other. Gum tape, unlike adhesive tape, requires an auxiliary device that immerses water in the glue part after use. Gum tape is mainly used for packaging in manufacturing factories that handle paper products. Gum tape is used for all packaging of base paper shipped from paper manufacturers. In the present application, the “adhesive tape” does not include a gummed tape.

  However, the tape cutter described above has a problem that it can be used only for an adhesive tape made of a thin film such as polypropylene (PP) or polyethylene terephthalate (PET). Moreover, there existed a problem that a special tape cutter other than an adhesive tape was required.

  When a film such as paper or polypropylene is applied to a part of the adhesive surface, or varnishing or dusting is applied, the thickness increases by the amount of paper or film, and the paper, film, powder, etc. Therefore, there is a problem that it is not easy to apply paper or dust on the structure.

  The conventional pressure-sensitive adhesive tape has a problem that it is troublesome because it is necessary to search for and remove an end serving as a take-out port from the roll of the pressure-sensitive adhesive tape when used. In addition, when disassembling an object such as cardboard assembled with adhesive tape after use, the opener may cut his hand when using the cutter knife, or the contents may be damaged by the cutter knife. There was a problem that there was. Further, the adhesive tape remaining on the corrugated cardboard has a problem that it needs to be removed when the corrugated cardboard is recycled as resource waste by repulping or the like. Further, when the cardboard is reused, if the remaining pressure-sensitive adhesive tape is not peeled off, the pressure-sensitive adhesive tape is stuck on the pressure-sensitive adhesive tape, and a new pressure-sensitive adhesive tape is peeled off immediately. Therefore, when recycling or reusing, it is necessary to remove the adhesive tape, but there is a problem that it is not easy to remove the adhesive tape from the object with a finger and it takes time.

  Therefore, the present invention is based on the problems that such conventional adhesive tapes have, and can easily form an end portion that does not stick to the hand without using a large-scale instrument. Moreover, it aims at providing the adhesive tape which can be done without increasing thickness.

  In the first aspect of the present invention, an adhesive and a non-adhesive part appear alternately on the back side of the base material by applying an adhesive in a strip shape in the width direction with a certain interval in the length direction. Provided is a pressure-sensitive adhesive tape provided with formed horizontal stripes and having a release agent coated on the surface side of a substrate.

  The length of the non-adhesive part is 10 mm or more and 20 mm or less, the length of the adhesive part is 1 to 2 times the length of the non-adhesive part, and a full width adhesive is applied to the adhesive part. It is preferable. Moreover, it is preferable that the color, the pattern, or the character is provided in the part whose back side is the said non-adhesion part in the surface side of a base material. Depending on the color, characters, or pattern, the adhesive tape can be used as a mark when it is cut and used as a grip portion, and the adhesive tape is convenient and easy to use for the user.

  The pressure-sensitive adhesive tape of the present invention is configured as described above, and according to the pressure-sensitive adhesive tape of the present invention, it is easy to form an end portion that does not stick to the hand without using a large-scale instrument. It can be done without increasing the thickness.

It is a perspective view which shows the back surface side of the adhesive tape of Example 1 of this invention. It is a perspective view which shows the surface side of the adhesive tape of Example 1 of this invention. It is a cross-sectional enlarged view of the adhesive tape of Example 1 of this invention.

  Hereinafter, an embodiment of the pressure-sensitive adhesive tape of the present invention will be specifically described using examples with reference to the drawings, but the present invention is not limited thereto.

(Constitution)
FIG. 1 is a perspective view showing the back side of an adhesive tape of Example 1 of the present invention. FIG. 2 is a perspective view showing the surface side of the adhesive tape of Example 1 of the present invention. FIG. 3 is an enlarged cross-sectional view of the adhesive tape of Example 1 of the present invention. FIG. 3 is an explanatory diagram showing an enlarged part of a cross-section of the tape cut in the length direction with the surface side of the tape facing up.

  The pressure-sensitive adhesive tape 1 of Example 1 has adhesive portions 4 (in FIG. 1) that are alternately applied to the back surface 3 side of the substrate 10 by applying an adhesive in a strip shape in the width direction with a certain interval in the length direction. A horizontal stripe formed by a colored portion on the back side of the tape and a non-adhesive portion 5 (a white portion on the back side of the tape in FIG. 1) is provided, and a release agent 12 is applied to the surface 2 side of the substrate 10. The pressure-sensitive adhesive tape 1 of Example 1 is in a state where the base material 10 is wound around the core 9 which is a paper tube made of paper, with the back surface 2 side, that is, the pressure-sensitive adhesive surface inside.

  At the time of use, pull the end of the winding end on the outer surface of the adhesive tape 1 to pull out an arbitrary length, and cut it in the width direction near the center of the non-adhesive part 5 with a hand or an attached simple cutting tool or scissors And use it. In this embodiment, a simple cutting tool 8 is attached (not shown in FIG. 1).

  The end portion 11 formed by cutting is non-adhesive and serves as a tab serving as a grip portion to be gripped with fingers without being bent. In the present application, the length direction means the long side direction of the tape, that is, the winding direction (extension direction) of the tape, and the width direction means the direction perpendicular to the length direction, that is, the short side direction of the tape. .

  The length of the non-adhesive portion 5 is 15 mm in this embodiment, but the length of the non-adhesive portion 5 is not long enough to be grasped with fingers if both ends are about 5 to 7 mm when cut near the center of the non-adhesive portion 5. Since the adhesive end portion 11 is formed, the length of the non-adhesive portion 5 is preferably 10 mm or more. However, if the non-adhesive portion 5 is too long, sufficient adhesive force cannot be exhibited when the adhesive tape is applied to cardboard or the like, and therefore the length of the non-adhesive portion 5 is preferably 20 mm or less. The length of the bonding portion 4 is preferably 1 to 2 times the length of the non-bonding portion 5. A full width adhesive is applied to the bonding portion 4.

  The substrate 10 is unbleached kraft paper (brown) or bleached kraft paper (white) in Example 1, but the substrate is other paper, cloth, film such as polypropylene or polyethylene terephthalate, metal foil, or the like. May be. The adhesive tape is manufactured by providing adhesive portions 4 and non-adhesive portions 5 on the entire back surface by applying an adhesive on the back surface at regular intervals with a certain interval in the length direction and in a strip shape in the width direction. The substrate 10 is wound around a large roll of about 2000 m, then cut to a predetermined length such as 50 m and wound around a core. That is, by applying the adhesive in a striped manner, a “part without glue” is created from the beginning at the stage of manufacturing the original tape. In this embodiment, the adhesive tape is a 50-m roll having a width of 50 mm, but is not limited thereto.

  In this embodiment, a mark indicating whether the back surface 3 side is the bonded portion 4 or the non-bonded portion 5 is provided. In the present embodiment, on the front surface 2 side of the base material 10, there is a non-adhesive portion display portion 6 (colored portion on the tape front side in FIGS. 1 and 2) that is a front side portion of the portion having the non-adhesive portion 5 on the back surface 3. The bonded portion display portion 7 (the white portion on the front side of the tape in FIGS. 1 and 2), which is color-printed and is the front side portion of the portion having the adhesive portion 4 on the back surface 3, does not print anything, and then removes the release agent. Apply. The non-adhesive portion display portion 6 may be printed with multicolor printing or a pattern or characters. Different colors, patterns, and characters may be printed so that the non-adhesive part display unit 6 and the non-adhesive part display unit 6 can be distinguished from each other. In this embodiment, silicon is used as the release agent.

  Because it is possible to distinguish between non-adhesive locations and adhesive locations, the location suitable for cutting when using an adhesive tape to attach it to the adherend such as cardboard, etc. It is possible to indicate to the user whether this is the case, so that convenience is enhanced.

  According to this embodiment, the back surface side of the base material is formed with an adhesive portion and a non-adhesive portion that appear alternately by applying an adhesive in a strip shape in the width direction with a certain interval in the length direction. Horizontal strips are provided and a release agent is applied to the surface side of the base material, so it is easy to form an end that does not stick to the hand when using it, without requiring a large instrument. It can be done without increasing the thickness. In addition, the grip portion can be formed without the need for bending the tape. Therefore, the entire adhesive tape attached to the adherend can be smoothly peeled off. Further, since a color, a pattern, or a character is provided in a portion where the back surface is a non-adhesive portion on the front surface side of the base material, it is easy to search for the outlet (tip) of the wound adhesive tape. The amount of adhesive can also be greatly reduced.

  No special tape cutter or the like is required for peeling, no extra processing material is required, no difficulty in operation, and no cost is increased. Since a cutter knife is not required when peeling the adhesive tape from an adherend such as corrugated cardboard, there is no fear of cutting hands and there is no worry of damaging the contents.

  Since the length of the non-adhesive part is 10 mm or more and 20 mm or less, the length of the adhesive part is 1 to 2 times the length of the non-adhesive part, and the full width adhesive is applied to the adhesive part, Even fingers can be easily cut at the non-adhesive part, but adhesion is sufficient and can be easily removed when peeled off. Accordingly, since the adhesive tape is peeled off from the adherend such as cardboard and recycled, recycling to toilet paper, the core of the cardboard and the like becomes easy. Further, since the old adhesive tape is peeled off when the adherend is reused, the new adhesive tape is well bonded to the adherend.

  Not only thin film adhesive tape but also thick Kraft adhesive tape can be easily peeled off. Since the adhesive part 4 and the non-adhesive part 5 are provided endlessly without being interrupted from end to end at the original fabric stage, it can be used without waste until the end.

  The adhesive tape of this example is not suitable for packing that requires airtightness or packing heavy objects because the overall adhesiveness is slightly lowered, but it can be widely used for normal packaging, and is covered by use. Not only the workability is improved in the peeling work from the kimono, but also the ecological viewpoint is considered as described above.

  The present invention is not limited to the embodiments described in the above-described embodiments, and various modifications can be made without departing from the spirit of the invention.
