Coding is a crucial step in packaging. Regulations require product packaging to display information like expiration dates and batch numbers. Industries like food and pharmaceuticals often demand even more detailed coding. Regardless of your industry, you need a clear and reliable coding solution. Below, we introduce five common coding machines that, when paired with packaging machines, can greatly enhance your production efficiency.
Laser Coding Machine
One of the most common solutions is the laser coder.
Laser coding machines use focused laser beams to mark surfaces with high precision and permanent codes, making them ideal for high-speed production environments. They can mark materials like glass, metal, and plastic with expiration dates, serial numbers, or batch codes.
Laser printing machines are different types, such as CO₂ lasers for general use, fiber lasers for harder materials, and UV lasers for delicate materials.
Laser coders require minimal maintenance and deliver high-quality, non-contact markings, making them suitable for food, beverage, and pharmaceutical industries.
Hot Ink Roller Coding Machine
Hot ink roller coders use heated ink rollers to print codes on packaging materials. These machines are commonly used for simple date or batch codes and are often paired with flow packing machines.
Hot Ink Roller (Thermal) Coding Machines are widely used in food and pharmaceutical industries, providing economical and fast coding for paper and plastic surfaces. Best suited for medium-speed production lines, ink rollers typically measure 35-36mm in diameter and 40cm in length. However, regular ink roller replacement is required.
Inkjet Printer (Continuous and Thermal Inkjet)
Inkjet coders are versatile and can print on a wide range of surfaces, including curved or uneven ones. Inkjet Printing machines are suitable for high-speed production lines and capable of printing variable data such as QR codes, barcodes, and graphics. Continuous Inkjet (CIJ) systems are ideal for industrial applications, while Thermal Inkjet (TIJ) systems are compact and better suited for small-scale operations. These Inkjet printers are commonly used in the beverage, cosmetics, and electronics industries.
Thermal Transfer Printer
Thermal transfer coders use heat and ribbons to transfer ink onto surfaces, providing clear and durable prints. They are widely used for flexible packaging, such as films or small pouches, and are the preferred choice for industries requiring high-resolution barcodes or graphics. With printing speeds of 50-200 codes per minute, these thermal transfer printing machines allow users to control coding data through an LCD screen. They are ideal for environments where coding data frequently changes, offering excellent flexibility and high-quality output.
Ribbon Hot Coding Machine(Colorful-tape printer)
Ribbon hot coders are a cost-effective option that uses heat and ribbons to imprint codes on packaging materials. Hot date printers are suitable for simple coding tasks, especially on paper, plastic films, or pre-printed materials. For small to medium production lines, they provide an economical and efficient solution. To change the code, you need to replace the character set on the coder, and additional English characters may need to be purchased. Ribbon replacement is required periodically. These ribbon hot printing machines are commonly used with vertical packing machine and pre-made bag packaging equipment.
By combining these coding machines with packaging systems, you can meet diverse industry and coding requirements. When selecting a coding device, consider compatibility with your packaging machine, production speed, surface materials, and code durability.
