Purchase-order checks
- Grade and thickness
- Surface on one or both sides
- PVC or laser film requirement
- Flatness and scratch acceptance
- Mill-origin finish sample where appearance is critical
Protection and acceptance
- Specify one-side or two-side surface quality
- Select PVC, PE or laser film for the downstream process
