Understanding how a factory schedules coating, slitting and die-cutting explains exactly what custom work should cost and how long it should take.
The thread running through this guide is 1 inch round color-coded dot labels, circular die-cuts used for status, rotation and color-coded workflow signals. When it is specified and converted correctly, operations gain instant visual status coding, a quiet advantage that compounds across thousands of labels. Xinwei's role as factory-direct producer, not reseller, is what makes that consistency achievable in airline, airport and baggage handling.
- Lock the approved golden sample and require bulk to match it
- Check core and winding direction on every custom specification
- Review the program quarterly against scan-fail and jam data
- Confirm restricted-substance declarations, including BPA-free options
- Decide roll versus fanfold from station layout and changeover labor
- Write down the minimum application temperature, including freezer scenarios
- Abuse-test samples through water, grease, cold or abrasion as the job requires
- Compare supplier quotes on identical written specifications
Q: Are direct thermal labels the same as thermal transfer labels?
No. Direct thermal images the coating itself and needs no ribbon, suiting labels with a service life from days to months or a few years with premium topcoats. Thermal transfer melts ribbon ink onto a neutral face and suits multi-year, outdoor or chemical-heavy service. Most airline, airport and baggage handling work, including 1 inch round color-coded dot labels, is best served by well-coated direct thermal stock.
Q: How do I compare two supplier quotes fairly?
Align every spec: facestock, coating grade, adhesive, liner, dimensions and tolerances, core, winding, labels per roll and packaging. Then compare traceability, sample policy, capacity and defect terms. Finally, trial both on real bag tags, cargo bins and unit-load devices through ramp weather, conveyor crushing and extreme hold temperatures and grade scans at high-speed baggage induction arrays.
Q: Are film-faced thermal labels worth the extra cost?
Where labels face tearing, immersion, long reuse cycles or short outdoor exposure, yes: PP/BOPP faces eliminate tear failure and re-labeling labor. For ordinary shipping and shelf life, top-coated paper is the smarter cost. A manufacturer recommends the honest minimum.
Q: Do thermal labels work on plastic, glass and textured surfaces?
They do when adhesive and facestock match the surface: conformable faces for curves, high-tack films for textured HDPE and woven sacks, and clean surfaces at the right application temperature. The surface triangle of material, temperature and time must be solved deliberately.
Q: What is a golden sample and why keep one?
It is the approved physical reference for face, die, winding, print behavior and packaging. Every bulk delivery is compared against it, which blocks silent substitution and makes quality disputes objective. Factories welcome golden samples; traders struggle to match them.
