Description

[Detailed explanation of the idea] This invention relates to a record protection sheet.

In order to protect record discs from dust and impact, a protective sheet with an adhesive layer is attached to the disc surface so that it can be easily peeled off.

Conventionally, paper has been used as the base material for this record protection sheet, but it has poor moisture resistance, and the record protection sheet may curl due to the influence of moisture, or it may float after being attached to the record. There were drawbacks such as wrinkles and the inability to perform a sufficient function.

In addition, as a way to solve this problem, the base material of the record protection sheet is made of plastic sheets, but these sheets are easily charged with static electricity, and are particularly susceptible to damage from records. Since the protective sheet is significantly charged when it is removed, dust tends to accumulate on the record after the protective sheet is removed, which can actually damage the record. .

As a means to prevent such charging, attempts have been made to make the base material of the protective sheet made of non-woven fabric mixed with metal powder, such as carbon or aluminum powder. It is necessary to add at least an additional part of metal powder.If the amount added is increased, the nonwoven fabric itself becomes brittle and weak in strength, and at the same time, the appearance deteriorates and becomes unsightly. There was a problem.

In view of the above, this invention was made with the aim of providing a record protection sheet that has excellent moisture resistance and can effectively prevent static electricity.It is made of a plastic-based nonwoven fabric with metal vapor deposition on the surface. It is characterized by having an adhesive layer provided on one side of a base material.

Next, this invention will be explained using examples.

FIG. 1 is a perspective view of an embodiment of this invention, and FIG. 2 is an enlarged sectional view of the main parts of the embodiment.

The record protection sheet 1 of this invention is constructed by providing an adhesive layer 13 on one side of a plastic-based nonwoven fabric substrate 12 on which a metal thin film 11 is formed, the surface of which is vapor-deposited with a metal such as aluminum. It is configured so that the adhesive layer 13 is pasted facing the record A.

Note that 2 in the figure is a release paper.

In the above embodiment, the amount of metal deposited is greater than the amount of metal relative to the base material 12 made of nonwoven fabric.

In the above embodiment, the adhesive layer 13 was provided on one side of the nonwoven fabric base material 12 opposite to the metal vapor-deposited surface.
As shown in the figure, a configuration may be adopted in which an adhesive layer 13 is provided in an overlapping manner on the surface on which metal vapor deposition is applied.

Electrification tends to occur when plastic materials are rubbed together with other objects, or when a plastic sheet pasted with an adhesive is removed, so for example, to prevent electrification when putting a record in and out of its jacket. In order to prevent charging when the protective sheet 1 is peeled off from a record, the structure shown in FIG. 3 is used.

In order to prevent static electricity when storing the jacket and when peeling the protective sheet 1 from the record, a non-woven fabric base material 12 (not shown) is coated with metal vapor deposition on both the front and back surfaces.
It is also possible to have a configuration in which the adhesive layer 13 is provided on one side.

Since this device is constructed as described above, it is possible to effectively prevent charging of the protective sheet 1 made of plastic with the metal thin film 11 formed by metal vapor deposition, and the metal necessary for preventing static electricity is formed by vapor deposition. Since the base material 12 is made of plastic-based non-woven fabric, there is no possibility of weakening of the base material due to contamination with metals, which is the case in the past. It does not become distorted and has various practical effects such as a solid appearance because it does not have the same surface gloss as plastic film.
