How to Add 1D and 2D Codes to Flexible Labels
Introduction
Flexible film labels are widely used for product identification, component tracking, and packaging in automotive and industrial production. Adding 1D barcodes and 2D codes to these labels turns them into machine-readable carriers that support traceability, inventory control, and quality documentation. Because flexible label materials can stretch, curl, or shift during handling, applying codes to them requires a controlled process rather than a simple printing step. This guide explains how 1D and 2D codes are added to flexible labels in an automated fiber laser marking setup, covering the label materials involved, the working principle, the step-by-step process, and the factors that affect marking quality.
Understanding 1D and 2D Codes on Flexible Labels
A 1D barcode encodes data in a single line of variable-width bars and spaces. A 2D code, such as a matrix or stacked code, stores data in two dimensions, which allows more information in a smaller area. On flexible labels, both code types are used to carry identification data such as part numbers, serial numbers, batch information, or production dates.
The key difference for flexible labels is the substrate. Unlike rigid metal or plastic nameplates, flexible film labels can deform under mechanical stress. The marking method must therefore create a permanent code without damaging the label or causing it to distort. Fiber laser marking is one method used for this purpose, because it produces a durable mark through controlled interaction with the label surface.
Product Overview: Fiber Laser Marking Machine for Flexible Labels
The KINMARK Flexible Fiber Laser Marking Machine is designed for laser marking on flexible film labels from brands such as TESA, 3M, and Schreiner. It supports automated processing that includes unwinding, inspection, leveling, marking, and cutting. The system integrates these steps into one automated solution for producing customized identification labels with stable quality.
The machine is intended for flexible label processing where permanent marking of characters, texts, graphics, 1D barcodes, and 2D codes is required. Its modular design allows adaptation to different production requirements and provides integration options for industrial applications.
Label Materials and Compatibility
The equipment is suitable for various brands of ethyl acetate based laser film, including TESA, 3M, and Schreiner labels. These materials are processed through the automated sequence to produce the labels required by the customer. Because the machine is designed around flexible film labels, the material handling stages are configured to manage the specific behavior of thin, flexible substrates.
Working Principle of Fiber Laser Marking on Flexible Labels
Fiber laser marking uses a focused laser beam to create a permanent mark on the label surface. The beam is directed according to the code pattern, so characters, graphics, 1D barcodes, and 2D codes can be produced directly from digital data. On flexible labels, the process is combined with mechanical handling that keeps the material flat and stable during marking.
The automated sequence supports this principle in practice. Unwinding presents the label material to the marking area. Inspection checks the material before marking. Leveling ensures the label is flat and positioned correctly. Marking applies the code. Cutting separates the finished label. This sequence reduces the chance of distortion or misalignment that could affect code readability.
How to Add 1D and 2D Codes to Flexible Labels: Step-by-Step
The following steps describe how codes are added to flexible labels in an automated fiber laser marking process. The exact settings depend on the label material and the required code format, but the sequence reflects the standard workflow of the equipment.
Step 1: Prepare the Code Data
Define the content to be encoded, such as a serial number, part number, or batch identifier. Prepare the 1D or 2D code as digital data that the marking system can use. The code content should match the traceability requirement of the production process.
Step 2: Load the Flexible Label Material
Load the flexible film label roll into the unwinding section. The material may be a TESA, 3M, or Schreiner label, or another compatible ethyl acetate based laser film. Correct loading keeps the web aligned as it moves through the machine.
Step 3: Inspect the Label Web
The inspection stage checks the label material before marking. This step helps identify material issues before the code is applied, so that defective sections are not marked unnecessarily.
Step 4: Level and Position the Label
Leveling prepares the label surface for marking. A flat, stable label allows the laser to produce a consistent code. This is particularly important for flexible materials, which can otherwise shift or wrinkle during processing.
Step 5: Mark the 1D or 2D Code
The fiber laser marks the code onto the label. The system can produce characters, texts, graphics, 1D barcodes, and 2D codes. The marking is permanent and designed to remain readable on the flexible label surface.
Step 6: Cut and Collect the Finished Label
After marking, the cutting stage separates the finished label from the web. The completed label is then ready for application or further processing. The automated sequence supports efficient production of customized labels with stable quality.

Factors That Affect 1D and 2D Code Quality on Flexible Labels
Several practical factors influence how well a code can be marked and read on a flexible label.
Label Material and Surface
Different flexible film labels respond differently to laser marking. The material type, coating, and thickness affect the contrast and permanence of the mark. Using a material that is compatible with the process, such as the supported TESA, 3M, and Schreiner labels, helps maintain consistent results.
Web Tension and Leveling
Because flexible labels can stretch or wrinkle, maintaining proper web tension and leveling the label before marking are important. A flat label produces a more accurate code shape, which supports reliable scanning.
Code Size and Data Density
2D codes can store more data in a smaller area than 1D barcodes, but they also require sufficient marking resolution. The code size should be matched to the available label area and the reading equipment used downstream.
Marking Position Accuracy
Consistent positioning ensures that the code appears in the intended location on each label. The automated handling and leveling stages help maintain this consistency across a production run.
Applications of Flexible Labels with 1D and 2D Codes
Flexible labels with laser-marked codes are used in industrial environments where durable identification and traceability are required. Typical application areas include:
Automotive manufacturing: Component and part identification labels that support production tracking.
Automotive components: Labels for parts that require serial numbers or batch codes.
New energy vehicles: Identification labels for battery, powertrain, and electronic components.
Powertrain manufacturing: Traceability labels for engines, transmissions, and related assemblies.
Intelligent factory automation: Machine-readable labels that integrate with automated inspection and logistics systems.
In each case, the label carries the code that allows the part or product to be identified and tracked through the production process.
Benefits of Automated Fiber Laser Marking for Flexible Labels
Improved traceability: Permanent 1D and 2D codes provide a reliable link between a physical label and its associated production data.
Better process consistency: Automated unwinding, inspection, leveling, marking, and cutting reduce variation caused by manual handling.
Production integration: The modular design supports integration into existing industrial workflows.
Reduced manual handling: Combining multiple process steps in one system limits the need to move flexible labels between separate stations.
Quality management support: Clear, permanent marking helps maintain readable codes for downstream scanning and verification.
