Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a sheet-like material.

[0002]

2. Description of the Related Art Conventionally, there has been known a sheet-like material formed by laminating a transparent silicone agent on a transparent polyethylene sheet to form a silicon layer. Such a sheet-like material such as hot melt or adhesive is known. By covering the adhesive, the sheet-like material can be easily peeled off from the adhesive when the adhesive is used, and the adhesive is protected until the adhesive is used. However, since the silicon layer in this conventional sheet is made of a transparent material, it is difficult to visually determine whether or not the silicon layer has been formed on the sheet during manufacturing. Therefore, it is the current situation to check the presence or absence of a silicon layer by irradiating the sheet-like material with fluorescent X-rays, and it is time-consuming to determine the silicon layer by such a method,
Equipment for fluorescent X-ray irradiation is also required. When the hot melt is wrapped, it is difficult to visually determine whether or not the hot melt is wrapped because the entire sheet is transparent. Hot melt is used, for example, by using a hot-melt discharge device equipped with a heating furnace and a discharge nozzle, and using the hot-melt in a heating furnace to melt the hot melt and discharge it from the discharge nozzle. At the time of use, if it is difficult to visually determine whether or not the hot melt is wrapped with the sheet material as described above, the sheet material is put into a heating furnace in a state of being wrapped without peeling from the hot melt. As a result, when discharging the hot melt from the discharge nozzle of the hot melt discharge device, the sheet-like material is also sent to the discharge nozzle, and the discharge nozzle is clogged with the sheet-like material, and the hot melt is discharged. There is a problem that the ejection becomes impossible. On the other hand, conventionally, a colored sheet-like material has been proposed. In this colored sheet, for example, as shown in FIG. 10, a coloring material b is arranged between two transparent polyethylene sheets a1 and a2, and an upper surface of the upper polyethylene sheet a1 and a lower polyethylene sheet are arranged. A transparent silicon layer c, c is formed on each lower surface of a2. If the hot melt is wrapped with such a colored sheet, it is visually determined whether or not the hot melt is wrapped. it can. However, also in this case, since the silicon layers c and c themselves are transparent, it is difficult to visually determine the presence or absence of the silicon layers c and c in the sheet-like material at the time of manufacture, as described above.
Further, when the sheet-like material is manufactured in this way, the manufacturing process and material costs are increased, and the manufacturing cost is high.

[0003]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above circumstances, and it is a first object of the present invention to provide a sheet-like material capable of visually determining the presence or absence of a silicon layer.

[0004] The present invention provides a sheet material suitable for a packaging sheet of an adhesive such as a hot melt or an adhesive which can be easily and visually discriminated as to whether or not it is packaged, and which can be manufactured at low cost. This is the second purpose.
