Decision Checklist: Which Machine Is Right for Your Production Line?
Choosing a continuous band sealer that features coding technology is something that many people will find very easy to get lost in the specific coding technology of choice alone. However, there are so many other things that should be considered before you actually make your final decision, such as the type of packaging material that you use, as well as the overall cost of using it. This guide will reveal the differences between a laster marking and inkjet coding band sealer.
Many production lines still rely on traditional coding systems. While these systems can meet basic coding needs, they have the following pain points that make coding technology necessary:
The traditional coding technology uses ink, which needs to be continuously supplied with ink, solvents, and cleaners. It adds up the cost of operation due to the fact that there is an ongoing cost of consumables.
Furthermore, the print nozzles used can get clogged or leak at any time. The result of this is that printing will need regular cleaning and maintenance. This can reduce the efficiency of printing and order fulfillment, especially in high-production lines.
The production date, batch number, and bar code should be clearly visible throughout the entire chain of logistics.
Traditional ink codes can wear out, smudge, or become unreadable as a result of being exposed to water or rough handling. Codes not being readable can cause scanning problems, ineffective stock management, traceability issues, as well as product rejections during quality checks.
When producing certain products like food and pharmaceutical products, there should be strict clean-room standards for the production environment.
Traditional ink coding systems have been known to emit some volatile chemicals during the process of coding.
With different machines used to seal the packages and code the products, the packaging process becomes complicated due to the need for extra floor space, extra operator involvement, and coordination of two different production processes.
This is because if the two processes become misaligned, there would be errors in printing which could result in wastage and inefficiency in the production process.
Compared with traditional standalone systems, integrated solutions can offer:
Decreased footprint of machinery due to the combination of two operations in one machine.
Less manual intervention leading to increased efficiency.
Consistent coding and printing.
Minimal need for maintenance, especially for laser marking machines that have no ink to maintain.
Increased traceability with readable coding.
A laser marking band sealer can burn and mark the surface of the package through a concentrated laser beam while at the same time sealing the bag. Unlike other coding methods, laser marking does not use any ink or ribbons.
Since the code is burned into the package surface, it will not smudge, smear, or rub out during transportation or storage.
Laser marking machines are ideal for manufacturers who have high-throughput operations where durable and high-contrast codes are required without frequent maintenance.
Hualian's FRJ-1120W UV Laser Marking Continuous Band Sealer integrates continuous sealing, UV laser coding, counting, and touchscreen controls into one machine. Its integrated design simplifies production while eliminating the recurring cost of printing consumables.

High precision: Laser marking systems offer high-quality, sharp character prints that enhance barcode scanning and tracking capabilities.
Consistent quality: Without ink cartridges to change and no printheads to become clogged, print quality is guaranteed during extended run times.
Thermal inkjet technology excels when production requires frequent content changes or more complex printed information.
Unlike many traditional coding methods, modern thermal inkjet systems can print:
QR codes
Barcodes
Company logos
Product graphics
Multiple languages
Variable serial numbers
Promotional messages
This flexibility allows manufacturers producing private label items, seasonal packs or variations of their products to change data easily and effectively.
In CO₂ laser marking, high-contrast permanent marking is achieved through thermal marking, which involves chemical interaction with the material surface. CO₂ laser marking works best when applied to packaging materials that need good visibility and readability.
Recommended materials:
Transparent plastic bags
Kraft paper bags
Paper packaging
Dark plastic films
High-density packaging materials
Advantages
Ensures creation of highly readable characters that have high contrast.
Gives excellent marking quality on transparent bags, even when other laser systems do poorly.
Provides good versatility for marking paper-based and transparent materials.
Considerations
Since CO₂ lasers mark using heat, materials that are too thin or heat sensitive will have burn marks due to excessive processing.
However, thermal processing could create some amount of dust and smoke, and this makes more extraction systems necessary.
Best suited for
Companies whose primary form of packaging for their products is in transparent bags and kraft paper bags.
Businesses that need high-contrast permanent marking the most.
Marking by a water-cooled UV laser utilizes the process of cold marking; as a result, there is very little heat transfer into the packaging material. Thus, marking can be performed without burning the packaging material, making it perfect for applications that require maintaining strict levels of hygiene.
Recommended materials:
Opaque plastic films
Composite films
PE and PP packaging bags
Flexible packaging that does not require transparent substrates
Advantages
There is no high-temperature burning when marking.
Generation of very little carbonized material or smoke.
It helps to meet the requirements for cleanliness in food, pharmaceutical, and detergent industry manufacturing sites.
Prevention of thermal damage and material deformation.
Considerations
UV laser marking does not suit transparent bags, as the marks will look shallow and poorly contrasted, thus making them unreadable.
Therefore, it is better applied to opaque and composite packaging materials.
Best suited for
Food processing plants
Pharmaceutical manufacturers
Detergent and personal care production
Cleanroom and sterile workshop environments where contamination control is essential
Food manufacturers frequently work round-the-clock, packing thousands of items per hour. Laser marking allows you to keep dates of production, batches, and expiration dates clearly readable throughout the shelf-life period.
For food manufacturers using clear plastic bags or kraft paper packaging, a CO₂ laser marking machine would be ideal due to its high contrast and durable markings. For facilities requiring strict hygiene measures, it would be better to use a water-cooled UV laser since it will not produce any smoke or carbonization.
The pharmaceutical industry needs identification codes that are clear and permanent due to the regulations required. A water-cooled UV laser would be a great choice for the pharmaceutical industry due to the minimal effect of heat and clean processing.
Permanent marking of medical products is usually necessary for manufacturers. Lasers provide durable identification codes that do not fade or smear.
Contract packers can go from job to job all through the day. The first job might call for a company logo, whereas the second job may need barcodes or languages that are different from those used in the first job.
It is very easy to change the printing job when using the thermal inkjet technology since it makes the process fast and easy.
Producers of private labels do not print similar packages for a long time. Different retailers usually demand special logos, QR codes, and information about products. It is very convenient to change layouts in thermal inkjet printers.
Companies with moderate production volumes may find thermal inkjet offers an attractive balance between investment cost and coding flexibility.
The lower initial equipment cost makes it easier to add professional coding capabilities without the higher capital investment associated with laser systems.
The FRJ-1120W is an excellent choice for manufacturers seeking permanent coding without the recurring cost of consumables.
