Does printing on hollow-core boards really peel off easily? Professional test data reveals the truth.
Recent market research shows that 38% of consumers have concerns about the durability of printing on hollow-core boards (PP honeycomb panels). The main concerns focus on:
-
Pattern delamination caused by insufficient ink adhesion.
-
The fading issue after UV exposure
-
Scratches caused by transport friction
Let the authoritative test data speak for itself.
Verified by experiments conducted by the National Packaging Quality Inspection Center:
✅ Adhesion Test Adopting the ASTM D3359 standard, high-quality UV printing can achieve a rating of 4B (up to 5B).
✅ Wear resistance test RCA paper tape friction test: ≥300 cycles (standard packaging requirement: 150 cycles)
✅ Environmental testing Temperature cycle from -20℃ to 60℃ with no cracking.
Key technologies for enhancing robustness
-
Preprocessing process
Flame treatment/corona treatment increases the surface dyne value to over 40, boosting ink adhesion by 300%. -
Printing Method Selection
-
UV Digital Printing: Ideal for complex patterns, with a curing speed of 0.3 seconds per color.
-
Screen printing: The ink layer thickness reaches 15–30 μm, offering the best abrasion resistance.
-
-
Coating Protection Plan
A water-based varnish coating can increase the number of abrasion-resistant cycles to over 500.
Shopping Recommendations
The three key factors for identifying high-quality printed hollow boards:
-
Observe whether jagged edges appear at the print edges (an accuracy of less than 0.1 mm is preferred).
-
Use 3M tape to perform a simple adhesion test (no peeling indicates pass).
-
Request the SGS report to confirm that the heavy metal content meets the standards.
