Abstract

According to an embodiment of the present invention, a sheet for packing a substrate is placed between multiple substrates to sequentially separate each of the substrates by reducing static electricity between the substrates in order to pack the substrates by laminating the same. The sheet includes: a first surface including a first contact area making contact with a first substrate, and a first noncontact area not making contact with the first substrate; and a second surface forming the opposite surface to the first surface, and including a second contact area making contact with a second substrate and a second noncontact area not making contact with the second substrate. The first noncontact area is depressed from the first contact area to the second surface in order to prevent a mark on the first substrate, caused by pressure generated when multiple substrates are laminated. The second noncontact area is depressed from the second contact area to the first surface in order to prevent a mark on the second substrate, caused by the pressure generated when multiple substrates are laminated.

Description

{Sheet for packaging substrates}

The present invention relates to a sheet for packaging a substrate, and more particularly to a sheet for packaging a substrate used for stacking and packaging a plurality of substrates produced.

In general, a substrate is a kind of plate in which an electric circuit is knitted and can be used for a display device such as a liquid crystal display (LCD), a plasma display panel (PDP), an organic EL,

Such a substrate can be automatically produced by a predetermined process, and the produced substrates must be packed for the next process.

Conventionally, a substrate is packaged in a box for packaging and transported and stored. In particular, a plurality of substrates housed in a box are vertically supported while being spaced apart from each other by a predetermined distance so as not to contact each other.

However, the above-described method has a problem in that when the substrate is bent during movement, the distance between the substrates is required due to the possibility of mutual contact between the substrates, which increases the size of the box considerably.

As a result, as the size of the substrate increases, the spacing distance must be further increased to prevent contact between the substrates, and the size of the box becomes considerably large, which results in a problem that the storage and transportation efficiency is lowered.

In this regard, a method of disposing a protective film between substrates in order to improve the efficiency of packaging of a substrate has been proposed. However, when the protective film is later removed, static electricity is generated between the substrate and the protective film Which caused an additional problem that removal was difficult.

The present applicant has solved the above problem through KR10-1368089. However, when the substrate is stacked due to the protrusions formed on the sheet, a mark formed by the protrusion is formed on the substrate, Can not be used).

Therefore, the present invention is to propose an invention for preventing the occurrence of a mark by the sheet during the substrate stacking, thereby preventing the substrate from being defective.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet for packaging a substrate, which improves the efficiency of packaging and minimizes static electricity during the separation of the substrate when the produced substrates are laminated and packed, thereby maximizing the process efficiency at the time of removal.
