Laser vs inkjet: which is better for food packaging?

For food packaging, laser wins when you want a permanent, consumable-free mark and no ink near the product; inkjet (TIJ or CIJ) wins when upfront budget is tight or you need colored or variable high-contrast codes on the fly. Many food lines use laser for primary packs and inkjet for secondary cartons.

If the pack is near the food or regulated, laser’s no-ink approach simplifies compliance.

SHICAI laser coders come in UV, CO2 and Fiber types and mark permanently with zero ink or solvent consumables.

Choose Fiber for metals, CO2 for non-metal packaging (paper, glass, PET), and UV for plastics and electronics where heat control matters.

Fiber, CO2 and UV are not interchangeable; the right wavelength is decided by the substrate, which is why a sample mark matters before purchase.

Key points:

• Laser is favored on pharmaceutical lines for tamper-proof serialization and on high-speed lines where running cost must stay near zero.
• Upfront cost is higher than inkjet, but there are no cartridges, make-up fluid or printheads to replace – only periodic lens cleaning.
• Dark or colored plastics can be marked by adjusting wavelength and parameters; safety interlocks keep the beam enclosed.

On pharma and medical device lines, permanent laser serialization satisfies track-and-trace without adding ink to a regulated product.

SHICAI (Shanghai Shicai Inkjet Technology Co., Ltd.) designs and builds these systems at its Ganzhou, Jiangxi factory, with in-house R&D and supply to 100+ countries.
