The Role of Barcodes in Packaging and Logistics
Barcode systems one of the most fundamental elements of the supply chain . Barcodes on packaging ensure accurate tracking of every stage of a product's journey from the warehouse to the customer. In logistics, a barcode isn't just a label; it represents speed, accuracy, and reliability
However, barcodes that are poorly printed, erased, or lose their durability under environmental conditions can lead to disruptions in logistics processes, increased costs, and customer dissatisfaction. This is why the concept of "durable barcoding" has become a critical issue in recent years.
Problems Encountered in Barcoding Processes
- Erasability: Barcodes can become unreadable due to moisture, friction, or sunlight.
- Incorrect Positioning: Placing the barcode on the wrong surface makes it difficult for scanners to read it.
- Low Contrast: Insufficient resolution or incorrect ink selection reduces readability.
- Logistical Challenges: Conditions experienced during storage and transportation affect the quality of the barcode.
These problems undermine the barcode's most basic function: traceability .
Solutions for Durable Barcoding
Laser Barcoding
Laser marking creates permanent barcodes by altering the surface at the micron level. Laser barcodes applied to packaging or logistics equipment are resistant to chemicals, moisture, and heat.
Advantages:
- Indelible, permanent and high contrast
- Ideal for small QR codes and DataMatrix signs
- Waste-free and environmentally friendly
Inkjet Barcoding
Inkjet systems offer a practical solution, especially for high-speed production lines. With the appropriate ink selection, readable barcodes can be achieved on plastic, cardboard, or film surfaces.
Advantages:
- Quick implementation
- Compatible with different surfaces
- Lower initial cost
Thermal Transfer Barcoding
Thermal transfer printing, particularly used in label-based applications, offers high resolution. However, its physical durability is not as strong as laser printing in logistics.
The Importance of Barcode Readability in Logistics
First-time barcode readability is a critical efficiency criterion in warehousing, transportation, and distribution processes. Incorrect or unreadable barcodes:
- Process delays,
- Wrong shipment,
- Increasing costs,
- to customer complaints .
Therefore, barcodes must not only be printed accurately, but also be durable .
Digital Tracking with QR Code and DataMatrix
Alongside traditional barcodes, QR codes and DataMatrix are increasingly used in logistics. These codes can fit much more information into a smaller space and offer digital verification.
- Product information
- Supplier ID
- Shipment data
- Customer verification
QR codes processed with laser marking also contribute to the prevention of counterfeiting.
Sectoral Applications
Food and Beverage Logistics
In cold chain processes, barcodes must be resistant to humidity and low temperatures. Laser coding is the most suitable solution for these conditions.
E-Commerce and Distribution
Inkjet systems provide fast and practical barcoding in high-volume product shipments.
Pharmaceutical and Healthcare Sector
DataMatrix has become mandatory for pharmaceutical packaging to combat counterfeiting. Laser marking is the standard solution in this area.
Best Practices for Durable Barcoding
- The correct method suitable for the packaging surface must be selected.
- Barcode positioning should be done to ensure ease of use for scanning.
- The contrast level should be tested and checked with verification cameras.
- Laser marking should be preferred for critical products.
Frequently Asked Questions (FAQ)
1. What packaging can laser barcoding be used on?
It can be applied to cardboard, plastic, metal, and glass surfaces.
2. What's the difference between inkjet and laser?
Inkjet is fast and cost-effective, while laser is more permanent and reliable.
3. Is using QR codes advantageous in logistics?
Yes. QR codes contain more data and increase traceability.
4. How do I ensure barcode readability?
With correct positioning, contrast testing, and camera-based verification.
In the packaging and logistics industry, barcoding ensures products reach the right destination at the right time. However, the quality and durability of the barcodes are critical factors in the success of the process.
