Food Packaging Marking & Coding Solutions

Few industries are as highly regulated as food production and packaging. As with pharmaceutical development and chemical manufacturing, food industry professionals must comply with relevant laws, standards, and regulations to place their products in stores. From state-level meat and dairy coding regulations to the Fair Packaging and Labeling Act (FPLA), food manufacturers and co-packers must honor certain guidelines or face expensive fines and product recalls.

Depending on product specifics, food companies often need to label packaging with the following:

Lot codes
Serial numbers
Expiration dates
Barcodes/data matrices

For over 30 years, InkJet, Inc. has helped companies complete coding and marking on food packaging. With our diverse marking solutions and specialty inks, you can create efficient marking workflows for ongoing regulatory compliance.

Comply With Food Industry Marking Standards With Custom Printing Solutions

The need for unbroken traceability has gradually risen as food supply chains have expanded in scope and complexity. To ensure public safety and mitigate food concerns, state and local governments worldwide issue traceability regulations to counteract:

Higher risks of food spoilage due to longer supply chains
The proliferation of counterfeit products sold through online retailers
A higher likelihood of contamination from widely-sourced ingredients

Regulations vary by food sector and geographical location, but they all aim to minimize quality control issues via traceable product markings. With the help of lot codes, batch numbers, and other traceable markings, companies can:

Source all product ingredients
Trace the ingredients supply chain movement before facility arrival
Track products during distribution and warehousing until the final point of sale
More accurately recall products in emergency cases

To comply with food packaging marking and coding regulations, companies must have the proper hardware to create long-lasting, highly readable product codes. That’s where InkJet, Inc. can help.

	The Anser U2 Pro-S Thermal Inkjet Printer: Compact and cost-effective, the Anser U2 Pro-S is a great choice for operations that don’t require CIJ-level marking speeds. Like the Anser U2 Smart and SmartOne, the Anser U2 Pro-S has 76.2 m/min max speed and 400 x 300 DPI max resolution. However, the Anser U2 Pro-S is compatible with more materials, for the printer can mark porous, semi-porous, and non-porous substrates.
	The Anser A1 Thermal Inkjet Printer: The first all-in-one TIJ that offers 2” printing and mid-message DPI adjustments, the Anser A1 is both powerful and affordable. Built with 2 cartridge slots, the A1 can create 2” tall markings with varying DPI elements (e.g., 300 DPI QR code with 150 DPI text). These qualities make the A1 an excellent case coding printer. For product marking applications, the A1 maxes out at 300 m/min with certain cartridges. Users control the A1 through a large touchscreen interface.
	The Anser X1 Thermal Inkjet Printer: Even though the Anser X1 is a thermal inkjet printer, you wouldn’t know that from its spec sheet. With printing speeds up to 300 m/min, the Anser X1 is one of the most powerful TIJs on the market today. Beyond industrial speed marking, the Anser X1 offers a 600 DPI max resolution, a 3.87” max print height (with stitched printheads), IP66 protection, and the ability to simultaneously control two production lines.

Laser Marking Solutions: Fiber, CO2, and UV Laser Models

Laser marking systems are perfect for food packaging companies that require high coding speeds, reliable accuracy, and exceptional code appearance. For example, large-scale operations frequently use laser systems to meet demanding quotas, minimize coding errors, and enhance their products’ visual appeal. As laser marking systems have become more affordable, they have become increasingly popular with smaller-scale companies as well.

Laser systems are more expensive than TIJ and CIJ printers upfront, but they do not use any consumables. Moreover, they have minimal maintenance needs and do not require annual servicing. Depending on your product output, these factors can actually make laser marking more cost-effective than inkjet printing.

Inkjet Inc. offers four laser models:

Our laser systems offer similar specifications and benefits. The F8100F, F8100C, LDR7100, and F8100U provide:
