The purpose of the present invention is to improve a self-adhesion-type adhesive tape for banding branches, stems, vines, young shoots and the like of plants. A self-adhesion-type adhesive tape is produced, which comprises a tape-shaped backing and an adhesive agent applied onto one surface of the backing. An elastomer that constitutes the adhesive agent is prepared by mixing 10 to 80% by weight of a styrene-isoprene-styrene block polymer having a styrene content of 14 to 19% by weight inclusive with 20 to 90% by weight of a styrene-isoprene-styrene block polymer having a styrene content of 25 to 50% by weight inclusive. The self-adhesiveness retention property, i.e., such a property that, when parts of the adhesive agent on the self-adhesion-type adhesive tape are bounded to each other so as to form an A-shaped loop and a weight is suspended on the loop, the state of the suspension can be retained, is examined. The self-adhesion-type adhesive tape can achieve a sufficient level of self-adhesion property both in an environment having a temperature of 23C and an environment having a temperature of 40C.

Provided is a binding apparatus with which the quality of an object to be bound can be ensured and the burden on an operator can be reduced. A binding apparatus includes a pressure bonding mechanism in which pressure is applied by a pair of pressure bonding plates 34 and 35 to a joining portion of a binding tape 8, which is an adhesive tape, to fasten it together by gripping and squeezing a pair of levers 2 and 3 to rotate a pair of arms 4 and 5 around a fulcrum 6. Thereby, any mixing of metal staples into an object to be bound as in a conventional binding apparatus is eliminated, and thus the quality of the object to be bound can be ensured. Further, the need for a strong grip strength like that when ejecting a staple is eliminated, and thus the burden on an operator can be reduced.


Provided is a self-adhesive composition which can remedy the occurrence of residual adhesive when the self-adhesive agent is exposed to high temperatures, a self-adhesive sheet comprising the self-adhesive composition, and a method for producing the self-adhesive sheets. The self-adhesive composition comprising a styrene elastomer (component A) and an amorphous polypropylene elastomer (component B), wherein the component A is a hydrogenated product of a block copolymer formed by copolymerization of at least a polymer block comprising styrene compound-derived units, a block resulting from 1,2-vinyl polymerization of units derived from a diene compound 1, a block resulting from 1,4-addition polymerization of units derived from a diene compound 1, a block resulting from 1,2-vinyl polymerization of units derived from a diene compound 2, and a block resulting from 1,4-addition polymerization of units derived from a diene compound 2; and when the [tan]_(pmax) of the self-adhesive composition is 0.6 or more and less than 1.1, the content of the component A is 60 to 80 wt%, and when the [tan]_(pmax) of the self-adhesive composition is 1.1 to 3.0, the content of the component A is 50 to 80 wt%.
