DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material and a protection method for protecting a non-contact type IC tag used for the purpose of managing, for example, cleaning and rental uniforms.

[0002]

2. Description of the Related Art In recent years, non-contact type IC cards and IC tags have become widespread, and are used for individual management of information and products. In particular, the use of non-contact type IC tags is being studied in a wide range due to significant cost reduction, but one of them is for the purpose of managing cleaning and rental uniforms.

In conventional rental uniforms, individual management such as frequency of use is performed by attaching a tag on which a barcode is printed. However, it is actually difficult to read barcodes one by one. Product management was unstable, for example, items less than the number of times of cleaning or the period of use could be deleted.

Therefore, the use of a non-contact type IC tag for the above-mentioned purpose is very useful because the reading operation is efficient. However, because of its use, it must be stuck to clothing at all times, so that heat, water, solvent and pressure during cleaning are repeatedly applied, and there is a great possibility that the IC tag will not operate properly. .

The structure of an IC tag is such that an IC is mounted on a flexible substrate such as PET on which an antenna is formed, and a protective film is bonded via an adhesive. It was immersed in the adhesive interface and caused a failure, and heat was directly applied to the tag, which also caused a failure.

SUMMARY OF THE INVENTION An object of the present invention is to provide an IC
An object of the present invention is to provide a protective film and a protective method which are excellent in heat resistance, water resistance and solvent resistance for protecting a tag.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a protective film for protecting a management tag (IC tag) on which a non-contact readable IC is mounted, wherein the protective film is made of polyetheretherketone (PEEK). Formed of polyethersulfone (PES), polyetherimide (PEI), polysulfone (PSF), polyamide (PA), polyimide (PI), polyamideimide (PAI), or polytetrafluoroethylene (PTFE) material Protection film for IC tags. Furthermore, the present invention is a method for protecting an IC tag in which a small bag is formed by the above-mentioned protective film, and the IC tag is inserted therein and then sealed.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION As the protective film used in the present invention, a thermoplastic resin having excellent heat resistance and chemical resistance is suitable, and polyether ether ketone (PE) is used.
EK), polyethersulfone (PES), polyetherimide (PEI), polysulfone (PSF), polyamide (PA), polyimide (PI), polyamideimide (PAI), or polytetrafluoroethylene (PT
FE) material.

The method for protecting an IC tag according to the present invention includes the following:
Two upper and lower protective films, one size larger than the C tag, may be thermally welded on four sides and sealed, or an IC tag may be sandwiched between half-folded protective films and three sides may be thermally welded and sealed.

According to the present invention, it is possible to form an outer bag in advance by a method such as heat welding a thermoplastic plastic film having excellent heat resistance, water resistance and solvent resistance, insert an IC tag therein, and then seal it. preferable.

[0011] By the above means, the IC tag used for cleaning or managing the rental uniform can be protected from heat, water and solvent, and the life of the IC tag can be extended. Conditions for cleaning are as follows:
Several minutes in warm water at 70 ° C during washing, 10 minutes at 180 ° C during drying
And 5 to 10 minutes at 200 ° C. during pressing.

The solvent used for cleaning includes chlorine-based and chlorofluorocarbon-based solvents. The protective film of the present invention prevents the IC tag from directly contacting the solvent.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. The present invention is not particularly limited by the examples. FIG. 1 shows a protection form of a non-contact type IC tag according to a first embodiment of the present invention. The IC tag 1 is hermetically sealed by forming a welding seal part 3 on the protective film 2 by means of a heat welding seal to protect the IC tag from external water, solvent, etc., from directly touching the IC tag.
The protective film 2 is made of a thermoplastic resin such as polyetheretherketone (PEE) having excellent heat resistance and chemical resistance.
Use K). As a packaging method, two upper and lower protective films, one size larger than the IC tag, are heat-sealed on four sides and sealed.

FIG. 2 shows a protection form of a non-contact type IC tag according to a second embodiment of the present invention. The IC tag 1 is hermetically sealed by forming a welding seal portion 3 on the protective film 2 by heat sealing, thereby protecting the IC tag from direct contact with water or solvent from the outside. As the protective film 2, a thermoplastic resin made of polyetheretherketone (PEEK) having excellent heat resistance and chemical resistance
Use As a packaging method, the IC tag is sandwiched by a half-folded protective film that is slightly larger than the IC tag, and three sides are thermally welded and sealed.

[0016]

According to the present invention, by sealing the IC tag with a thermoplastic resin and a plastic film having excellent heat resistance and chemical resistance, the IC tag is protected from water and solvent at the time of cleaning. By reducing conduction, IC
Since the service life of the tag is extended, the reliability of the IC tag is improved.
