Thermal transfer overprinter technology will improve the coding level of flexible packaging labels

In order to ensure the safety of food and drugs, printing the production date, product batch number and other real-time information on the flexible packaging of food and drugs has become an important part of the production process of food and drugs. Real time information enables manufacturers to track products when needed and provide protection when products are recalled on a large scale. It can be said that coding technology has become an important part of modern quality system.

The latest laser and thermal transfer overprintercan greatly improve the problems existing in the traditional printer, especially the thermal transfer overprinter, which can not only improve the coding quality, but also improve the traceability of products, improve the reliability and flexibility of equipment, and is suitable for all kinds of soft packaging materials.

Technical advantages of thermal transfer overprinter

Technological innovation usually means that new technologies can bring higher product quality, faster production speed, lower production cost, more reliable operation performance and higher product added value.

Thermal transfer overprinter is mainly composed of tto print head, print tto ribbon and controller. The print head usually contains 8 to 12 dots per millimeter or 200-300 dots per inch (DPI), which can be quickly and continuously switched, so as to transfer the ink from the ribbon to the film to print the image. Due to the use of digital means, the printer can print "in real time", and can change the batch number and date information for intermittent and continuous packaging very quickly.

First of all, the thermal transfer overprinter does not use words, so there is no need to arrange and adjust small words, so as to avoid the risk of words falling into food or breaking the film, and there is no cost of replacing words; Secondly, thermal transfer overprinter can provide high-quality coding effect. The resolution of coding image can reach up to 300 dpi, and the printing quality is consistent and stable; It can print special characters and bar codes, pre store a large number of graphics or special characters in the library, and automatically change the code without shutdown or human error, so as to maintain a high level of production capacity; It can print real-time information and improve the traceability of products, which is particularly important today when food and drug safety are increasingly emphasized.

Flexible packaging is the most important category in the packaging industry, and the output value of flexible packaging products exceeds more than half of the packaging and printing industry. All kinds of paper, plastic, paper plastic, plastic plastic plastic, plastic aluminum flexible packaging are widely used to package leisure food, dry goods, baked goods, candy, chocolate, sliced frozen fresh food, frozen food, coffee, tea, powdered food, bagged drugs, hardware parts and other commodities.
