2. Description of the Related Art Etching parts such as shadow masks used for CRTs and lead frames used for semiconductors are manufactured by a photoetching method using a thin metal plate as a material, and have a single-wafer form. When transporting and storing single-wafer shadow masks and lead frames, for example, the stacked etching parts are packed with rust-proof paper, and the packing is hung with a flat compression plywood from above and below. It is a thing.

FIG. 1 is a perspective view showing an example of a package in which etching parts are packed. As shown in FIG. 1, the packaging of the etching component is such that the packaged etching component (13) is placed on the lower holding plate (11), and the upper holding plate (12) is placed on it. It was banded in 14). For example, in the case of a shadow mask having a size of about 15 inches, about 200 shadow masks are packed with rust preventive paper, and the lower holding plate (11) and the upper holding plate (12) are about the size. 20
A compression plywood having a size of cm × 30 cm and a thickness of about 5 mm is used. As the plastic band (14), for example, a polypropylene band having a band width of 15 mm and a thickness of 0.65 mm is used. The plastic band (14) is banded at two positions parallel to the short sides of the lower pressing plate (11) and the upper pressing plate (12), and at one position parallel to the long sides.

When the shadow mask transported and stored in such a packaging is used, a plastic band (1
4) is removed, the wrapped shadow mask is taken out, unwrapped and the shadow mask is taken out,
At this time, foreign matter may adhere to the shadow mask surface. The foreign substances that adhere to the surface of the shadow mask include metal particles, paper dust, and wood chips. When packing in such packaging, rust-proof paper wrapping work and compression plywood and polypropylene band wrapping work are performed in a clean environment. It is considered to be a foreign substance generated due to wear and impact during handling.

When such foreign matter scatters or floats and enters, for example, a hole of a shadow mask, a so-called "hole defect" is generated.
As a result, the shadow mask becomes a defective product. When the foreign matter is paper dust, wood chips, etc., it may be burnt out and disappear by the heat treatment during the CRT manufacturing process, but in the case of metal particles, it does not disappear and remains as a defective hole. Further, paper dust, wood chips, and the like attached to the surface of the shadow mask may make the shadow mask dent before the heat treatment in the process, and the shadow mask may be defective.

Looking at the state of the compression plywood and the polypropylene band used for packing, the compression plywood is hard,
The ends of the compression plywood will not bend even when banded with a polypropylene band, and will remain flat, and the corners of the compression plywood will not be deformed or the polypropylene band will not bite into the corners of the end. . However, the polypropylene band is slippery and tends to be rubbed in the arrow direction shown in FIG. 1 during handling after the band is put on. This rubbing of the polypropylene band during handling such as transportation and storage after banding contributes to the generation of wood chips.

In order to prevent such rubbing of the polypropylene band, it has been attempted to use a plastic corrugated cardboard sheet as a pressing plate instead of the compression plywood.
FIG. 2 is an exploded perspective view of an example of a plastic cardboard sheet. As shown in FIG. 2, the plastic corrugated cardboard sheet is composed of a plastic liner (22) used as a flat surface, a plurality of plastic ribs (23), and a plastic liner (21) used as a flat surface. Is.

The plurality of plastic ribs (23) correspond to corrugated cores of a paper corrugated cardboard sheet. Plastic corrugated cardboard sheet has bending strength and cushioning property in the rib direction, is superior in abrasion resistance, heat resistance, moisture resistance and decay resistance to paper corrugated cardboard sheet, and is lightweight. ing.

2) is placed and banded with a plastic band (34).

A plastic cardboard sheet is used for the lower pressing plate (31) and the upper pressing plate (32), and a polypropylene band is used for the plastic band (34). The direction of the plastic ribs forming the lower pressing plate (31) and the upper pressing plate (3
The rib direction of the plastic rib constituting 2) is parallel to the short sides of the lower pressing plate (31) and the upper pressing plate (32) as indicated by the thick arrow.

As shown in FIG. 4 (a), the cross section taken along the line CC 'is banded by a polypropylene band, but the ends of the lower pressing plate (31) and the upper pressing plate (32) are bent. It keeps a flat state, and the lower pressing plate (31) and the upper pressing plate (3
The corners at the end of 2) are not deformed and the polypropylene band does not bite into the corners of the end. That is, when the lower holding plate (31) is banded at right angles to the rib direction of the plastic ribs of the lower holding plate (31) and the rib direction of the plastic ribs of the upper holding plate (32), the packaging is performed as described above. Therefore, the peripheral portion of the shadow mask located below the banded polypropylene band, that is, the peripheral portion of the shadow mask shown in (c) in the figure is in a flat state.

As shown in FIG. 4B, AA '
In the cross section of the wire, since it is not banded by the polypropylene band, the ends of the lower pressing plate (31) and the upper pressing plate (32) are not bent, and keep a flat state. Therefore, the peripheral portion of the shadow mask located below the unbanded portion, that is, the peripheral portion of the shadow mask shown in (a) in the figure is in a flat state.

On the other hand, as shown in FIG. 4C, BB '
The cross section of the wire is banded by a polypropylene band, and the ends of the lower pressing plate (31) and the upper pressing plate (32) are bent, and are not flat. Further, the corners at the ends of the lower pressing plate (31) and the upper pressing plate (32) are compressed and deformed, and the polypropylene band is in a state of biting into the corners at the ends. That is, when the lower holding plate (31) is banded in parallel with the rib direction of the plastic ribs of the lower holding plate (31) and the rib direction of the plastic ribs of the upper holding plate (32), the polypropylene band ends in the above state. Since it digs into the corners of the polypropylene band, the polypropylene band is well fixed and prevents rubbing during handling.

However, the peripheral edge of the shadow mask located below the banded polypropylene band, that is, the peripheral edge of the shadow mask shown in FIG. 3B is also located at the lower pressing plate (31) and the upper pressing plate. (3
It becomes curved like 2). Thus, it is not preferable that a part of the peripheral portion of the shadow mask is bent.
