PVC Card Base Material
문제 현상
PVC cards delaminated after lamination
원인 분석
Improper lamination temperature and pressure or poor ink adhesion caused weak interlayer bonding; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
해결 방법
Optimize lamination parameters according to card structure; match ink with substrate; sample-check peel strength; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
핵심 요약
Card lamination relies on parameter and material matching; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
