| Abstract: |
| This paper aims to present a blockchain-based traceability management system for plastic packaging for food contact to solve the problems of incomplete, untimely, easy-to-tamper, and unguaranteed authenticity and integrity of tracing data in the whole circulation process of plastic packaging for food contact. This paper analyzed the feasibility and necessity of combining the blockchain technology with traceability management of plastic packaging for food contact from the application of blockchain at present and from the aspects of technical principle. It made up for the problems of traditional plastic packaging data easy to be tampered, embezzled and lack of authenticity, released whole-process traceability of materials for food contact and guaranteed food safety. The blockchain technology can be applied to the data storage, information transfer, and verification modes of traceability systems. |
