Challenges of Marking on Edible Oil Packaging How KGK Jet CIJ and Laser Machines Deliver Reliable Solutions

In the edible oil industry, packaging plays a vital role in ensuring product safety, quality, and brand identity. Whether it’s flexible pouches, PET bottles, or Tetra Pak cartons, every pack must carry critical information such as batch numbers, manufacturing dates, and expiry details. However, printing clear, permanent, and smudge-free codes on these diverse packaging materials poses multiple challenges for manufacturers using Form Fill Seal (FFS)—both vertical and horizontal systems.

Challenges in Marking on Edible Oil Packaging

1. Oily and Greasy Surfaces:
   Edible oils often splash or leak during filling, leaving a thin oil film on the packaging surface. This makes it difficult for conventional inkjet printers to achieve adhesion, leading to poor code quality or complete code absence.
2. Varied Packaging Materials:
   Edible oils are packed in multiple formats—plastic pouches, PET bottles, and laminated Tetra Pak cartons—each with different surface properties. A single printer must adapt to all, which is a demanding requirement for most coding systems.
3. High-Speed FFS Machines:
   Both vertical and horizontal FFS machines operate at very high speeds. The printer must synchronize perfectly with these lines to print accurate and consistent codes without slowing production.
4. Dust, Humidity, and Temperature:
   Oil filling environments often experience humidity, airborne oil particles, and fluctuating temperatures. These environmental factors can affect printer performance, ink flow, and nozzle health, resulting in downtime and maintenance issues.
5. Seasonal Production Cycles:
   Many edible oil units operate seasonally, meaning the printers might remain idle for long periods. When restarted, inkjet printers often need extensive cleaning or servicing, delaying production restarts.

KGK Jet CIJ & Laser Printers – The Perfect Solution

KGK Jet understands these challenges and has engineered CIJ (Continuous Inkjet) and Laser marking machines precisely for the edible oil industry’s demanding conditions. Designed for reliability, flexibility, and performance, these systems deliver perfect coding on pouches, PET bottles, and Tetra Pak cartons.

1. Positive Air Pressure Protection

KGK Jet CIJ printers feature a Positive Air Pressure System that prevents ink build-up caused by oil splashback. It also blocks dust and humidity from entering the print head, ensuring stable operation even in harsh environments.

2. Dedicated Ink Development Laboratory

With a strong in-house R&D setup, KGK Jet formulates specialized inks tailored for the chemical and food packaging sectors. The oil-resistant and dust-resistant inks ensure high adhesion and contrast on oily or non-porous surfaces like PET and laminated films.

3. Auto Start and Stop – Perfect for Seasonal Production

Unique Auto Maintain and Auto Start technology keeps the CIJ printer operational even after long idle periods. This eliminates the need for manual cleaning or flushing, allowing instant printing when production resumes.

4. Built for Tough Environments

Housed in a durable stainless-steel cabinet with a sealed IP65-rated electronics enclosure, KGK Jet printers are ideal for dusty, humid, or oily production zones. The system’s robust construction ensures uninterrupted coding performance.

5. Minimal Maintenance

Engineered for dependability, KGK Jet CIJ printers require minimal maintenance, drastically reducing production downtime and ensuring consistent operation with low running costs.

Laser Coding Option

For brands seeking a permanent, ink-free solution, KGK Jet’s Laser Marking Machines offer non-contact, maintenance-free operation with clear and indelible codes. Perfect for PET bottles and Tetra Pak cartons, laser systems ensure zero risk of code smudging or chemical interaction.

Conclusion

Coding edible oil packaging comes with complex challenges—from oily surfaces to seasonal downtime—but KGK Jet’s CIJ and Laser marking solutions effectively overcome them. With positive air pressure protection, oil-resistant inks, auto-start technology, and rugged IP65 design, KGK Jet ensures reliable, high-quality batch coding on every edible oil pack—pouch, PET bottle, or Tetra Pak.

For manufacturers seeking a smart, durable, and efficient Automatic Batch Coding Machine, KGK Jet stands as the trusted partner in ensuring every pack is perfectly marked, every time.
