What is a coding tape

Coding tape, also known as thermal printing tape or transfer tape for numbers, is a consumable used for coding machines, especially for character grain coding machines. The following is a detailed introduction to coding bands:

1、 Basic composition

The coding tape mainly consists of the following parts:

Belt base: usually made of thin and strong polyester or other high-density materials, providing a stable support structure for the ribbon.

Bottom coat: located on the front side of the substrate, used to ensure uniform ink color and complete transfer of ink color during printing.

Ink layer: Ink containing wax, resin, or mixed base, used to form text or patterns on printing materials.

Outer coating: located on top of the ink layer, used to protect the ink and enhance the adhesion between the printed material and the ink during printing.

Back coating: located on the back of the substrate, usually containing lubricant to prevent wear and damage to the print head, while also helping to evenly heat and reduce friction.

2、 Working principle

The working principle of the coding tape is based on thermal transfer printing technology. During the coding process, the print head of the coding machine heats the coding tape, causing the ink layer to melt and transfer to the flexible packaging film of the product, thereby forming clear text, batch number, or necessary text markings.

3、 Characteristics and advantages

Easy to use: The coding tape is easy to install and replace, suitable for use with various coding machines.

Clear handwriting: The printed text or pattern is clear, durable, and not easily peeled off or blurred.

Quick drying: The printed ink dries quickly, improving production efficiency.

Wide applicability: Widely used in industries such as pharmaceuticals, food, and packaging, suitable for printing production dates, batch numbers, and necessary text labels on product flexible packaging films.

4、 Precautions

Choose the appropriate specifications: Based on the model of the coding machine and printing requirements, select the appropriate coding tape specifications.

Correct installation: Ensure that the coding tape is installed correctly to avoid issues such as offset or breakage during the printing process.

Regular replacement: Regularly check the usage of the coding tape and replace worn or aged ribbons in a timely manner to ensure printing quality.

Storage conditions: The coding tape should be stored in a dry, ventilated, and dark environment, avoiding moisture, high temperatures, or direct sunlight.

5、 Application Fields

The coding tape has a wide range of applications in industries such as pharmaceuticals, food, and packaging. For example, in the pharmaceutical industry, coding tapes are used to print production dates, batch numbers, and other information on drug packaging; In the food industry, coding tape is used to print production date, shelf life, and other information on food packaging; In the packaging industry, coding tape is used to print labels or patterns on various packaging materials.

In summary, coding tape is an important consumable for coding machines, with advantages such as easy use, clear handwriting, and fast drying, playing an important role in multiple industries.
