Plastic products containing luminescent substances and methods for distinguishing authenticity thereof

Abstract

Disclosed is a plastic product capable of distinguishing authenticity from false, characterized in that the plastic product includes: a device, formed of a plastic material; and a luminescent substance, contained in the device, and emitting for incident light having a first wavelength The authenticity discrimination is performed by detecting the emitted light after irradiating the incident light with the emitted light having the second wavelength. According to the present invention, there is an effect that authenticity discrimination of a plastic product can be easily performed by a simple method of detecting the emission spectrum emitted from the plastic product.

Description

technical field [0001] This application claims the benefit of priority based on Korean Patent Application No. 2018-0147771 filed on November 26, 2018, all contents disclosed in the documents of this Korean Patent Application are incorporated as a part of this specification. [0002] The invention relates to a plastic product with easy authenticity identification and a authenticity identification method thereof. Background technique [0003] Plastics are lightweight and have excellent mechanical properties and processability, and are generally used in various products such as containers for consumer materials, cosmetics, pharmaceuticals, food, etc., automobile and aircraft parts, electronic products, and building materials. However, the number of counterfeit cases of plastic products made of unlicensed materials has recently been increasing, and this has become a problem.

Problems solved by technology

However, the number of cases of counterfeiting of plastic products made of unapproved materials has recently increased, which has become a problem

Plastic products have the following problems: After molding or processing, or final productization, it is difficult to determine whether they are genuine products made of approved materials, and when a part of the overall volume is made of an inexpensive substitute material, it is difficult to distinguish its authenticity. in fact impossible

For example, if it is faked to observe an approximate image, it may be difficult for consumers to distinguish the authenticity only through visual observation.

[0008] In addition, due to the fact that it is easy to confirm with the naked eye that a security element is applied to a specific position of a product, it may be relatively easy to carry out counterfeiting

[0009] In addition, such technology can basically only affect the visual appearance of plastic products and has limitations in the scope of application.
