Once the product needs to be recalled, it can send a short message directly to consumers to realize accurate recall.
3. On-line coding with laser coding equipment: Through cold laser on-line coding equipment and laser coding system, the safety traceability code is coded on the packaging surface, and consumers can also trace the relevant information through mobile phone scanning code. Pollution-free, zero consumables, clear coding, ensuring that the traceability code will not be replaced.
