Abstract

PURPOSE:To provide a self-adhesive kraft tape which is easy to produce and has a reduced slipperiness by coating one surface of a kraft tape material with an adhesive and the other surface with a release agent comprising a mixture of PVA and a silicone emulsion. CONSTITUTION:An acrylic or rubber-based adhesive 3 is applied on one surface 2a of a tape material 2 comprising a kraft paper. Then, a release agent 4 comprising a mixture of polyvinyl alcohol and a silicone emulsion is applied on the other surface 2b to prepare a self-adhesive kraft tape 1. Thus, the filling function by the polyvinyl alcohol and the delamination function by the silicone emulsion can be imparted simultaneously by applying the release agent 4 once. Further, the rear surface 5 of the tape is rendered less slippery by the polyvinyl alcohol so that when loads covered by the adhesive tape 1 on the surface are piled up during transporation, it seldom causes the shift or the like of the loads.

(Prior art) Traditionally, kraft adhesive tapes used for packaging, packaging, etc. are made by applying silicone treatment after PE lamination on one side of the kraft tape base material, and applying an adhesive to the other side. Although this is common, it requires two separate steps, including sealing with PE laminate and peeling off the back surface with silicone, making it troublesome to manufacture.

(Problem to be Solved by the Invention) However, although manufacturing is facilitated in one step as described above, the surface of the release agent made of a mixture of urethane and silicone is different from that of PE lamination followed by silicon treatment. , the slipperiness has been improved, but it is not sufficient (because the surface is highly slippery and slippery, if you stack and transport cargo such as cardboard whose outer surface is wrapped with these adhesive tapes, the tape's own back surface may The problem is that the surfaces of the release agent face each other and come into contact with each other, which can easily lead to collapse of the load depending on the loading angle, and there is currently a strong need for improvement.

(Effects of the Invention) The present invention provides a kraft adhesive tape in which an adhesive is applied to one side of a kraft tape base material and a release agent made of a mixture of polyvinyl alcohol and water-soluble silicone is applied to the other side.
By applying the release agent made from the above mixed solution once, the polyvinyl alcohol acts as a filler on the surface of the craft tape base material, and the water-soluble silicone acts as a release agent, making it possible to simultaneously apply both properties in one process. It is easy to manufacture, and the polyvinyl alcohol on the back of the tape reduces surface slippage and provides anti-slip properties, so when stacking and transporting cargo such as cardboard whose outer surface is packed with this craft adhesive tape, the back of the tape Even if the tape is in contact with each other or the back of the tape and the cardboard surface, it is difficult to slip, there is less risk of the load collapsing, and it is extremely easy to use, useful, and convenient, and it can fully meet the demands of customers and has product value. It has a high value.
