What inkjet printer is used for food and beverage packaging inkjet printing

Food and beverage packaging materials cover multiple types of plastic, glass, metal, cartons, etc. Food and beverage cij printers refer to the ability to print text, Inkjet coding equipment for patterns and other content, food and beverage inkjet printers include: small character inkjet printers, laser marking machines, high-resolution cij printers (UV inkjet printers and thermal foam inkjet printers), etc.

For food and beverage packaging, the production date and other signs are extremely important. In addition, with the acceleration of the construction of the national anti-counterfeiting traceability system, more and more food companies have begun to print anti-counterfeiting traceability barcodes on product packaging in order to solve the problems of anti-counterfeiting and anti-counterfeiting traceability in product production and sales.

1. Small character inkjet printer

Using the method of charged ink deflection to shift the ink dots out of normal flight The route is shot to the surface of the target printing material to form a dot matrix, thereby forming characters, numbers or graphics. Small characters are mainly used for simple digital coding such as production date and batch number, such as printing production date on beverage bottle caps. Application industries include food, beverage, and packaging industries.

In the food and beverage industry, such as bottle body printing date, batch number, small character inkjet printers are widely used, the ink drying speed is faster, and the printing distance is longer , The material requirements are also very low. However, the resolution of small character inkjet printers is not high, and the limitations are large, and the dotted non-solid fonts are printed out.

2. Laser marking machine

Software controls the deflection of the laser beam, and uses the high temperature of the laser to directly burn the products to be marked The surface or the molecular chain of the substance is broken by a laser to form characters or patterns. Laser marking machines have a wide range of applications. Most metal products will choose to use laser marking machines to mark text and patterns. The application industries include food, beverages, and packaging industries.

The laser marking machine does not require frequent replacement of consumables, it is more environmentally friendly than ink, the marking effect is clearer than small characters, and the marking is permanently difficult to be tampered with, but when the content is large, it is marked The speed is slow, and it is not suitable for printing high-precision bar code information.

3. High resolution cij printer

High Analysis inkjet printers include UV inkjet printers and thermal foam inkjet printers. UV inkjet printers refer to piezoelectric inkjet printers that use UV ink to print. Its working principle is the same as that of piezoelectric inkjet printers. Utilizing the characteristics of piezoelectric crystal deformation, UV ink jets fall on the surface of moving objects to form a dot matrix, thereby forming characters and patterns.

The nozzle of the thermal foaming inkjet printer adopts semiconductor thin film technology, and uses laser manufacturing process and high-precision deep layer technology to form a number of extremely small nozzle holes, which are high-density nozzles. Arrangement, the inkjet is energized and heated by the thin-film resistor, so that the ink produces countless tiny bubbles. The bubbles gather into large bubbles at a very fast speed and expand, forcing ink droplets to be ejected from the nozzle; when the resistor has no voltage, the heating is stopped, and there is no ink. Drops squirted out.

High resolution inkjet printers mainly print high-precision content, such as high-quality two-dimensional codes, barcodes, traceability codes, UDI codes, anti-counterfeiting codes, etc., which are widely used in food , Pharmaceuticals, daily chemicals, label printing, card making, packaging and printing, medical, electronics, hardware and other industries. In terms of printing quality, UV inkjet printers have better results, and the cost of consumables is much lower than that of thermal foam inkjet printers, which is suitable for large-scale mass production.

Summary: In the food and beverage industry, if you only need to print the third phase of the content, you can choose any of the cij printers; if you need to print barcode information, you can choose Laser marking machine or high-resolution inkjet printer; if the enterprise pursues production efficiency (fast production line speed) or the product needs to print more content, it is recommended to use high-resolution UV inkjet printer.

are present in just about every facet of modern life.
