DAC

The Role of DAC Codes in Product Tracking

A DAC code, often used as a compact 2D identifier, allows brands to track products through manufacturing, logistics, and retail environments. It stores key data in a small pattern that scanners can read quickly. Because the code works even at small sizes, it fits naturally on flexible packaging without interrupting design layouts.

Businesses use DAC codes to confirm authenticity, trace supply movement, and support automated workflows. GAIA sees these tracking tools appear more often on coffee bags, snack packaging, and health supplement pouches as brands strengthen their traceability systems.

Where DAC Codes Add Value in Daily Operations

DAC codes help teams maintain visibility across the supply chain. These common situations highlight how they support real-world processes.

Inventory handling

Products move through warehouses faster when systems can scan codes without depending on long barcodes.

Quality control

Tracking individual batches helps teams trace potential issues back to specific production runs.

Retail scanning

Compact data patterns allow retailers to verify product information even when packaging space is limited.

These uses show why DAC codes are becoming part of standard packaging workflows.

How DAC Codes Function on Packaging Materials

The design of a DAC code allows it to hold dense information in a small pattern. Scanners identify data based on contrast rather than size, so the code still works on films, varnished surfaces, or matte laminates.

Different substrates, however, influence readability. High-gloss finishes may cause reflections, while textured kraft surfaces can reduce contrast. GAIA works with brands that test code placement on various film types to ensure consistent scanning.

Ways Brands Integrate DAC Codes Into Their Packaging Strategy

DAC codes require thoughtful placement to support both usability and visual balance. Teams usually consider three elements when adding them to packaging.

Surface contrast

A clean background helps scanners interpret the code. Light areas often work better than dark zones.

Positioning

Codes placed near sealing lines or curved surfaces can distort. Flat, stable areas improve readability.

Printing method

Gravure, digital, and flexographic printing each create different edge sharpness. Teams match the printing method to the level of detail needed.

GAIA’s experience with diverse packaging formats—like shaped pouches and kraft laminates—helps brands find printing combinations that keep DAC codes accurate across full production runs.

How Teams Validate DAC Performance Before Full Deployment

Testing ensures the code works across equipment, lighting conditions, and distribution stages.

1. Teams try multiple scan angles to confirm consistent results.

2. They test readability after sealing, folding, or filling the pouch.

3. They check codes printed at different sizes to find the optimal balance.

4. They evaluate performance on each film type they plan to use.

5. They document best practices to maintain traceability across future batches.

These steps allow brands to introduce DAC codes without risking scanning failures once the product enters the market.

FAQ
