Choosing the Right Industrial Ink for Food Coding and Marking Industry

Inks

Hungry Shoppers Rarely Notice the Ink!!

At the end of a long day, most of us rush to the supermarket and grab something to eat. Maybe checking expiry dates but rarely pondering how that ink was developed. And why would we? Yet behind every innocuous code there’s a world of innovation. 

Advice for Food Coding and Marking Industry 

Those responsible for coding and marking industry must appreciate the complexity of marking inks. Quality, reliability, regulatory compliance, and cost all matter. Food producers must ensure both date codes and batch or traceability codes are printed to exacting standards—noncompliance can lead to heavy fines and reputational harm. 

Linx: Industial Ink Quality You Can Trust 

  • Linx industrial inks are batch-tested against ISO 9001 standards 
  • There’s no one-size-fits-all ink—Linx offers a broad range suited to food-grade applications, even direct‑print on eggs or cheese, as well as onto packaging substrates like cardboard, plastic, or glass

Specialised Industrial Ink Solutions for Tough Environments 

  • Harsh production environments: Fade‑resistant, quick‑dry, food‑certified inks that adhere even when surfaces are wet with alcohol-based cleaners. 
  • Retort processing: Proprietary black retort ink (Linx 1077) resists moisture, high heat, and ingredient migration—ideal when products are sterilised in their packaging. Thermochromic inks (purple-to-pink or black-to-blue) offer a visual cue that retort sterilisation has occurred. 

Black Industrial Inks for Food Coding and Marking Industry

Linx offers a diversified black-ink line: 

  • Black 1010: A fast-dry, high‑contrast dye ink that withstands sterilisation up to 200 °C. 
  • Plastic‑adherent 1014: Engineered for adhesion to plastics like PET, PVC, polycarbonate and ABS. 
  • Fast‑dry 1240/1405: From general-purpose performance ink (1–2 sec) to ultra-fast flow-wrap ink (<1 sec). 
  • Low‑odour, MEK/ketone‑free inks (e.g. 2030, 2035, mixed-base 3103/3240): For food or pharmaceuticals, including cleanrooms, meeting low‑fume and regulatory standards 
Industrial Inks and Fluids

Additional specialized options include oil‑penetrating or grease‑penetrating inks suited to oily or waxy surfaces, flexible packaging or humid environments. 

Food‑Grade Certified Inks 

Linx manufactures dedicated FDA‑approved (red 6100, blue 6120) and EU‑approved (blue 6220) inks for direct use on edible products, clinical apparatus or food wrappers. Each ink is produced in food‑dedicated facilities to avoid contamination, with storage and operating conditions optimized for safety and performance.  

While consumers rarely think about packaging ink, food manufacturers must. Choosing the right industrial ink ensures compliance, print clarity, code durability, and peace of mind—even in sterilisation, moisture, or oily‑surface conditions.
