Integrated Matrix Barcode Marking for Plastic Material Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic articles lack efficient and environmentally friendly methods to provide tracing information about their input materials, which hinders consumer awareness and sustainable purchasing decisions.
Innovation Solution
Integrate a computer-readable matrix barcode, such as a QR code, onto plastic articles during manufacturing to display tracing information about the input materials, including ingredient composition, source, and quantity, using a laser etching process to ensure durability and avoid additional materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional labeling methods are used to provide tracing information, then information can be displayed, but additional materials are added and environmental friendliness is reduced
Solution Approach 1:
The barcode is integrated directly into the plastic article structure during the molding process, merging the tracing information carrier with the product itself. This eliminates the need for separate labels, stickers, or tags, thereby avoiding additional materials that would harm the environment.
Solution Approach 2:
The plastic article serves dual functions: it performs its primary packaging/containing function and simultaneously carries tracing information through the integrated barcode. This multi-functionality eliminates the need for separate information-carrying components.
2Loss of information
If a barcode is added to plastic articles, then tracing information becomes accessible, but the manufacturing process becomes more complex
Solution Approach 1:
The barcode is created during the initial molding process rather than being added as a subsequent step. By incorporating the barcode design into the mold cavity, the tracing information is embedded in the plastic article during its formation, avoiding additional manufacturing steps and equipment.
3Loss of information
If conventional identification methods are used, then product identification is possible, but consumer awareness and informed purchasing decisions are hindered
Solution Approach 1:
The patent utilizes visual contrast through black barcode patterns on lighter plastic backgrounds, creating optically distinct regions that are easily scannable. This visual differentiation ensures consumers can easily locate and scan the barcode for tracing information.

AI summary
A system for marking a plastic article with a computer readable matrix barcode associated with input material used to form the plastic article is provided. The system includes a barcode applicator positioned downstream of an article forming operation. The barcode applicator is configured to provide a computer-readable matrix barcode on a surface of the plastic article. The system further includes a controller communicatively coupled to the barcode applicator. The controller has one or more processors configured to collectively: receive tracing information for one or more ingredients of the input material used to form the plastic article; generate the computer-readable matrix barcode scannable to display the received tracing information for each ingredient; and transmit, to the barcode applicator, one or more commands instructing the barcode applicator to provide the generated computer-readable matrix barcode on the surface of the plastic article.
