Case coding refers to printing critical information directly onto corrugated boxes or cases during the packaging process. This often includes barcodes, lot numbers, expiration dates, and other details necessary for compliance and traceability. By doing so, each case that leaves the production line is accurately marked, ensuring smooth inventory management, shipping, and fulfillment of retailer requirements.

Proper case coding goes beyond being a best practice — it's often a mandatory requirement. Its importance can be seen in several key areas:

• Traceability: Enables end-to-end product tracking across the supply chain, which is vital for recalls and quality inspections.
• Inventory Management: Clear labeling supports efficient stock rotation and smoother warehouse operations.
• Regulatory Compliance: Ensures adherence to industry standards in sectors like food, pharmaceuticals, and consumer goods.
• Retail Compliance: Major retailers, including Walmart and Target, demand accurate case coding to integrate with their logistics systems.
• Efficiency: Automated coding minimizes errors and keeps production lines running seamlessly.

Barcodes (1D and 2D), Lot and Batch Numbers, Production and Expiry Dates, Product Names and Descriptions, Logo & Branding, Shipping Details, Regulatory and Compliance Codes.

Using labels for case coding is still common, but labeling machines on production lines come with several disadvantages compared to direct printing:

• Higher Operating Costs – Labels require consumables (label stock, ribbons, adhesives), which add ongoing costs beyond ink or printhead maintenance.
• Material Waste – Backing liners and misapplied labels create extra waste, raising both disposal costs and environmental concerns.
• Downtime from Jams/Misfeeds – Labels can peel, wrinkle, or misalign, leading to frequent machine stoppages and production delays.
• Adhesion Issues – Labels may not stick well to dusty, cold, or uneven corrugated surfaces, risking compliance failures.
• Space & Maintenance – Labeling machines often require more mechanical components, meaning larger equipment footprint and higher maintenance needs.
• Aesthetic & Durability Concerns – Labels can tear or fall off during handling and shipping, whereas direct coding is permanent.
