Barcode-Label
Reliable optical marking for
industry, retail, and logistics
A barcode label is a label printed with machine-readable codes that stores data in optical form and can be read by barcode scanners or camera systems. Barcode labels form the basis for automated identification, traceability, and process control throughout the entire supply chain. Whether as a 1D barcode (barcode) or a 2D code such as a QR code, GS1 DataBar, or Data Matrix—the barcode label is an indispensable labeling tool in virtually all industrial, retail, and logistics sectors. Readability, material durability, standard-compliant print quality, and the correct font size are the decisive quality criteria.
PMG develops and manufactures barcode labels specifically tailored to the requirements of each application—from standardized industrial labels on rolls to custom solutions featuring individual logos and barcode generators.
Our product overview for RFID, barcode, and specialty labels showcases the full range of these solutions.
What is a barcode label?
A barcode label consists of a backing material, an adhesive layer, and a machine-readable print. The print encodes information such as product numbers, serial numbers, lot numbers, or delivery data in a visually readable pattern of bars, stripes, or symbols. A barcode scanner or camera captures this pattern and transmits the decoded data to a higher-level system—such as an inventory management, warehouse management, or production planning system.
Generally, there are different types of barcodes, for which we offer custom-made
BARCODE LABELS for every application:
1D codes (one-dimensional barcodes), also known as bar codes, consist of black bars and white spaces of varying widths. They store simple alphanumeric information such as product numbers or serial numbers and are the classic barcode used in retail and logistics. Well-known examples include the EAN-13 code, Code 39, Code 93, and Code 128, whose meanings and applications are explained in detail in our
BARCODE technology section for 1D and 2D codes.
2D codes (two-dimensional barcodes) such as QR Code, GS1 DataBar, or Data Matrix encode information in a grid structure of dots or squares. They can store many times the amount of data of a 1D code and are suitable for applications requiring a high volume of information on a limited label area, as we explain in our BARCODE
Substrate materials –
the intended use determines the choice
- The quality of a barcode label depends largely on the chosen substrate and printing method. Only when the print image, ink, and material are properly matched will the print remain machine-readable throughout its entire service life. The relevant standard for print quality is ISO/IEC 19421.
The selection of the appropriate substrate depends on several factors: - Surface to which the label is applied – alternative attachment methods such as loop labels, if applicable
- Mechanical, chemical, or thermal influences that could damage the label
- Weather and environmental influences such as exposure to moisture, cold, or UV light
- Required service life of the print and the label
- Preferred printing method (thermal transfer, direct thermal, flexographic, gravure, or offset printing, laser)
- Temperature resistance under extreme conditions such as furnaces or deep-freeze storage
- Security features for industrial or public use
Applications of Barcode Labels
Barcode labels are used across a wide range of industries—anywhere objects need to be permanently marked in a machine-readable format and there is a clear line of sight between the barcode and the scanner.
Typical applications for our marking and labeling solutions across various industries:
- Intralogistics and supply chain management
- Automotive industry and manufacturing marking
- Food and pharmaceutical labeling, including the Pharmaceutical Central Number (PZN)
- Electronics and printed circuit board marking
- Wholesale and retail
- Aviation and construction
Depending on the industry and application, standardized barcode types apply, as defined in standards such as ISO/IEC 15418. These standards specify data structures, prefixes, character strings, and representations, enabling manufacturer-independent, interoperable use of scanners.
Benefits of Barcode Labels
The use of barcode labels based on modern barcode technology offers measurable process benefits for every application:
- Fast and error-free data capture without manual entry
- Seamless traceability throughout the entire supply chain
- Automation of processes in order picking, shipping, warehousing, and production
- High data density in 2D codes – large amounts of information in a small space
- International standardization and easy integration into existing IT systems
- Cost efficiency through proven technology and widespread availability
- Improved customer service through faster and more accurate processes
What makes a good barcode label?
A high-quality barcode label must meet four essential requirements: durable and process-reliable application, material-specific resistance to environmental influences, reliable machine readability throughout its entire service life, and cost-effectiveness in the specific application context. In practice, these characteristics must be individually evaluated and optimized depending on the application.
PMG offers a broad product portfolio for this purpose, including
PMG OnMould barcode labels for products and containers in demanding industrial and logistics applications,
PMG InMould barcode labels for permanently integrated marking in injection molding,
PMG HighTemp+ Acid Pro labels for extreme temperatures and PCB marking, as well as
PMG Multi Surface labels for difficult surfaces.
Barcode labels as the foundation for reliable labeling
A barcode label is not a standard off-the-shelf product, but rather the result of a careful balance between substrate, printing process, compliance with standards, and the intended application environment. Choosing the wrong material or using subpar print quality leads to unreadable codes, process interruptions, and increased post-processing costs.
Through a combination of expert consultation, state-of-the-art production technology, and 100% final inspection, PMG ensures that barcode labels deliver consistently reliable reading results in every application, regardless of industry, material, or environmental conditions. Additionally, the use of a barcode generator and modern label design software allows for the customization of label size, font, and content.
It is also important to leave sufficient margin around the barcode during printing so that scanners can read the label without difficulty. Barcode labels are available in many variations, e.g., on paper or film, white or colored, removable or permanently adhesive, and in various sizes and formats, suitable for all requirements in warehousing, inventory, or shipping.
PMG offers customer-focused service and attractive deals with fast delivery, enabling companies to optimize their processes efficiently and cost-effectively.
FAQs
What is a barcode label and what is it used for?
A barcode label is a machine-readable label that stores data in the form of bars or symbols. It is used for the automatic identification and traceability of products, goods, and materials in industry, retail, and logistics.
What types of barcodes are there, and how do they differ?
There are one-dimensional barcodes (1D), which store information in the form of bars of varying widths, and two-dimensional barcodes (2D), which encode data in an array of dots or squares. Well-known types include the EAN-13 code, Code 39, Code 128, as well as QR codes and Data Matrix.
What materials are suitable for barcode labels?
Barcode labels can be made of paper or film, in various colors and with different adhesives, which can be permanent or removable depending on the application. The choice of material depends on requirements such as weather resistance, temperature, and mechanical stress.
How is the quality of a barcode label ensured?
Quality depends on the printing process, substrate, ink, and compliance with standards such as ISO/IEC 15416. A sufficient quiet zone around the barcode and the appropriate font size are important to ensure that scanners can read the code reliably.
How can companies benefit from using barcode labels?
Barcode labels enable faster, error-free data capture, improve traceability throughout the supply chain, and streamline processes in warehousing, shipping, and production. This helps reduce costs and improve customer service.
