Can low-cost core sheet increase total production cost?

Yes. Lower material price can be offset by registration loss, lamination defects, rework, lower punching yield, and more internal QA time.

Product Q&A

Q:How do I prevent PVC card curl after lamination?

Start by checking core-sheet shrinkage behavior and layer symmetry. Curl is often caused by unbalanced layer design or inconsistent thermal response, not only by lamination settings.

Q:What thickness should I choose for a standard CR80 card structure?

There is no universal answer without the full stack-up. Buyers should provide target finished thickness, overlay thickness, print layer plan, and whether an inlay is used.

Q:Why does card punching produce edge whitening or micro-cracks?

This can relate to material brittleness, poor lamination fusion, or unsuitable punching conditions. The core sheet must match the process window, not just the nominal thickness.

Q:Is white core always better than transparent core?

No. White core is better when opacity and clean print background matter. Transparent core is better for visual effects, window design, or special card constructions.

Q:What is the most important parameter when comparing suppliers?

For most engineering teams, it is the combination of thickness tolerance + shrinkage control, because these two directly affect lamination stability and final card consistency.
