How to Stop Ink from Flaking on Frozen Food Packaging

Frozen food packaging often suffers ink flaking below -18°C due to ink embrittlement. The solution involves three key steps:

1. Use Low-Temp Inks: Custom-formulated inks maintain flexibility and adhesion on common substrates (PE, PET, nylon) in extreme cold.

2. Optimize Printing: High-precision gravure printing with controlled pressure and speed, plus corona/plasma surface treatment, ensures deep ink penetration and strong bonding.

3. Test & Cure: Simulated cold-chain transport and freeze-thaw cycles validate performance. Heat curing boosts adhesion by >30% for abrasion resistance. All processes meet food safety and VOC standards.
