  • an objective of the present invention is to provide: a bag sealing tape which can be repeatedly used without damaging a banded object such a bag or the like when it is opened, and which does not have to be separated for disposal; and a banding device and a banding method using the bag sealing tape.
  • the bag sealing tape of the present invention is a bag sealing tape including adhesion zones and non-adhesion zones. Adhesion layers forming the adhesion zones are adhered to the surface of a base film in a stepping stone manner in a length direction of the base film. A user can easily hold the non-adhesion zones when opening a banding body, and thereby the bag sealing tape is convenient when being opened.

  • the adhesion zones adhered to the base film will not be peeled off when the user is opening a banding body. Therefore, in a case where a bag is banded again to preserve remaining contents, the bag sealing tape of the present invention can be repeatedly used with further certainty.
  • a ratio of a length of one of the adhesion zones to a length of one of the non-adhesion zones in the length direction of the bag sealing tape is from 9:1 to 1:1.5. With this, yield rate will improve since the bag sealing tape does not have excess adhesion zones or non-adhesion zones.

  • the difference (h 1 -h 2 ) between lengths of both non-adhesion zones is provided to enable both of the overlapping holding parts to be easily recognized and easily picked up by the user in the case where the user tries to open a banded portion by expanding the holding parts rightward and leftward or upward and downward, i.e., in opposing directions.
  • a gap may be provided between both of the holding parts that overlap with each other after being banded, by embossing the whole surface of one part of the non-adhesion zone. As a result, convenience when holding the holding parts improves.

  • the banding device includes a tape holder for holding the wound bag sealing tape, cutting means, and a cutting reference position adjusting mechanism.
  • the cutting reference position adjusting mechanism adjusts a cutting reference position such that a difference (h 1 -h 2 ) between a length (h 1 ) of the first non-adhesion zone and a length (h 2 ) of the second non-adhesion zone becomes a length that can be recognized by the user as a holding part after the cutting.
  • the cutting means is means for cutting the bag sealing tape, which has a cutting reference position adjusted by the cutting reference position adjusting mechanism, at the cutting reference position after the adjusting.
  • the banding device can set the difference (h 1 -h 2 ) of the non-adhesion zones at a length that the user can hold on, and thereby opening of the banding body becomes easy.
  • the cutting reference position adjusting mechanism preferably includes a gear shaped winding roller, a retention section, and a piston mechanism disposed at the retention section.
  • the bag sealing tape is arranged so as to envelop a gear of the winding roller, and a tip portion of the gear of the winding roller abuts the retention section via the bag sealing tape enveloping the tip portion of the gear.
  • the piston mechanism is a mechanism for adjusting, in a state where the tip portion of the gear abuts the retention section, a cutting reference position by urging the bag sealing tape, which is enveloping the tip portion of the gear, in a direction of a trough portion of the gear.
  • the banding device further includes a holding mechanism at a position preceding the winding roller.
  • the holding mechanism holds the non-adhesion portions of the bag sealing tape, and functions as a stopper for controlling an amount of movement of the bag sealing tape.
  • a banding method of the present invention is a banding method using the bag sealing tape which includes non-adhesion zones, and adhesion zones that are disposed on a surface of a base film in a stepping stone manner in a length direction of the base film.
  • the banding method includes: (1) a drawing step of drawing out, from a tape holder holding the bag sealing tape which is wound, the bag sealing tape by a cutting reference position adjusting mechanism; (2) a banding step of guiding the drawn bag sealing tape to a gear shaped winding roller which includes a trough portion for guiding a to-be-banded object, and guiding and banding the to-be-banded object while pressing thereof against the trough portion via the guided bag sealing tape; and (3) a cutting step of cutting one of the non-adhesion zones by cutting means disposed at a position following the winding roller to obtain a first non-adhesion zone and a second non-adhesion zone, such that a difference (h 1 -h 2 ) between a length (h 1 ) of the first non-adhesion zone and a length (h 2 ) of the second non-adhesion zone becomes a length recognizable as a holding part by a user.
  • the banding method can set the difference (h 1 -h 2 ) of the non-adhesion zones at a length that allows the holding part to be recognizable by the user, and thereby opening of the banding body becomes easy.
  • the cutting reference position adjusting mechanism includes a gear shaped winding roller, a retention section, and a piston mechanism disposed at the retention section.
  • the bag sealing tape is arranged so as to envelop a gear of the winding roller, and a tip portion of the gear of the winding roller abuts the retention section via the bag sealing tape enveloping the tip portion of the gear.
  • the piston mechanism is a mechanism which adjusts, in a state where the tip portion of the gear abuts the retention section, a cutting reference position by urging the bag sealing tape, which is enveloping the tip portion of the gear, forward and backward in a direction of a trough portion of the gear.
  • the banding method can adjust the cutting reference position of the bag sealing tape with more certainty, and a secure banding can be reproduced better. For example, even when a factory line is automated by using the present banding method and the banding bodies are mass-produced, the cutting reference position of the bag sealing tape can be adjusted with more certainty.

If the thickness is larger than 25 ⁇ m, the adhesive power is too strong and it becomes difficult to open the bag or the banded object 5 will be damaged upon opening; therefore, the objective of the present invention, which is not to damage the banded object 5 but to enable easy opening and re-banding, may not be achieved.
  • the method for applying the pressure sensitive adhesive on the base film 4 there is no particular limitation in the method for applying the pressure sensitive adhesive on the base film 4 , and various widely used methods can be used, including application methods using instruments such as brushes, spatulas, rollers, and caulking guns, and coating methods using dedicated equipment for mass production such as air sprays, nozzle sprays, roll coaters, beads, and the like.
  • coating is performed by using a die coater.
  • the base film is coated with a primer in accordance with needs, before having the pressure sensitive adhesive coated thereon.
  • the adhesion zones 2 are disposed on the surface of the base film 4 in a stepping stone manner in the longitudinal direction of the base film 4 .
  • the object 5 can be sufficiently banded by the adhesion zones 2 , and the non-adhesion zones 3 will appear at the ends of the bag sealing tape 1 after the cutting. Therefore, the user can easily hold the ends of the non-adhesion zones 3 , and the bag or the bag sealing tape 1 itself will not be damaged when opening the bag.
  • the peeling strength (A) is preferably smaller than the adhesion strength (B).
  • the peeling strength (A) is further preferably from 0.1 to 10 N/10 mm, particularly preferably from 1 to 8 N/10 mm, and extremely preferably from 3 to 5 N/10 mm. For example, there are cases where, when banding the object 5 , the length of one of the adhesion zones 2 is greater than the thickness (mid-portion circumference) of the banded object 5 and thereby the one adhesion zone 2 adheres itself.
  • the length of the adhesion zones 2 needs to be adjusted depending on the thickness (mid-portion circumference) of the banded object 5 .

  • the length of the non-adhesion zones 3 is also not particularly limited, and any length can be used as long as the length of the non-adhesion zones 3 is one that can be held by the user, and as long as the length of the non-adhesion zones 3 is in a range that does not cause a faulty banding due to having the length of the non-adhesion zones 3 being too lengthy thus inevitably having the length of the adhesion zones 2 too short.
  • the ratio of the length of the adhesion zones 2 to the length of the non-adhesion zones 3 is preferable from 9:1 to 1:1.5, further preferably from 7:1 to 1:1.2, and particularly preferably from 4:1 to 1:1.

Due to the relationship the ratio of lengths described above, if a 1-pitch length is shorter than 45 mm, the non-adhesion zones 3 becomes extremely short, and thereby it tends to be difficult for the user to hold on. Furthermore, if the 1-pitch length is longer than 100 mm, excessive adhesion zones 2 and non-adhesion zones 3 are produced and convenience tends to deteriorate.
  • a difference (h 1 -h 2 ) between a length (h 1 ) of the first non-adhesion zone 3 a and a length (h 2 ) of the second non-adhesion zone 3 b is preferably a length recognizable by the user as a holding part.
