Coding and Marking on Food Packaging

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.
