Bag marking of bulk materials
Marking of filled and unfilled paper and plastic bags Bags, big packs or pouches are often used as primary packaging when the product is in powdery, granular or chunky form. These can be made of paper as well as plastic. However, in addition tot he filling process itself, the clear and traceable marking of the bagged product is a required and very important issue. Heavy duty and industrial-suited Branchen und Produkte Bag marking must be fast and reliable without compromising on the print quality of the marking. This is because bag marking of bulk materials often takes place under rough and harsh environmental conditions. High dust pollution, temperature fluctuations or vibrations are the rule rather than the exception. High-contrast and well legible print results can be easily achieved here despite the difficult environmental conditions. In many industries, it is even required by regulations, customers or retail chains to apply high-resolution prints such as 1D and 2D codes. Bulk materials include the following branches and products: How to mark bags of bulk materials? Print distances, guiding rails, distance leveling device In the majority of cases, marking is done after the product has been filled into the bags or pouches. In this case, the filled bags move on conveyor belts and the marking is applied directly to the bags from above or from the side. The challenge with bag marking from the side is to ensure an even print area and the correct distance between the product and the print head. This is achieved by correctly guiding the filled bags using guide rails. Alternatively, a distance leveling device can be installed which follows the contour of the bag, always guiding the print head at the optimum distance from the product surface and thus compensating for different bag sizes and varying contours. If, on the other hand, marking takes place before the bags and pouches are filled, dust pollution generally plays a subordinate role. This also allows high resolution printing results to be achieved. Information such as barcodes or data matrix codes can then simply be printed directly onto the bags. Printing then usually takes place from above. Alternatively, labels can be applied by blowing or rolling. Suitable coding and marking systems for bulk materials Fast, sturdy, reliable Under which conditions the marking must take place, whether the marking takes place before filling or afterwards and which printing result is to be achieved, these are the requirements to be specified for a coding and marking system. Suitable REA coding and marking systems which have proven to work very well for bag marking: REA JET DOD 2.0 – Large Character Inkjet Printer: REA JET HR – High Resolution Inkjet Printers: REA JET GK 2.0 – High resolution inkjet printers: REA LABEL – Labeling technology:
Marking of respirator masks
Flexible and customer-specific marking of protective masks Respirator masks are an important part of personal protective equipment, found in almost every industry to protect employees, customers and patients against the finest particles. In times of Coronavirus pandemic, the fields of application of surgical masks, FFP2 respirators and FFP3 respirators have changed. Wherever people work together, move goods and operate machines, protection masks are used today. In some cases, there are currently misdeclared, misleadingly marked or non-certified products sold as protective equipment on the market. Marking is therefore a decisive factor for ensuring the required level of protection and safety. Marking of respirator masks different types: REA JET establishes itself as a coding and marking specialist in the production of respirator masks made of nonwovens, textiles and further materials. Well-known manufacturers count on REA. In contrast to tampon printing, our customers benefit from decisive advantages. Flexible text and logo change, contact-free, completely maintenance-free digital printing. The system recommendation is: REA JET HR, the high resolution inkjet printer.

Plastics Welding
Welding with digital printing technology Today, the high-precision laser welding process is increasingly used as an alternative to ultrasonic and high-frequency welding of plastics. A prerequisite is the reliable and economical application of a complex additive. In the past, there was no industrial solution for this. Together with partners, REA JET has developed a highly interesting digital printing process using REA JET Clearweld Primer for automation. Classically transparent plastics, such as PE, PP, PC, PS, SAN have naturally only a limited laser absorption capacity, making plastic welding impossible or very difficult. With the REA JET solution, transparent and laser-transparent plastic materials can be prepared with the REA JET Clearweld Primer, which has a high specific laser energy, so that they can be welded with lasers. Injection-molded plastic parts as well as non-woven fabrics can also be welded with this solution. Process Steps: It works in these three steps…
Glass
Direct marking of glass in the building and foodstuff industry Permanent markings of glass are often realized by light. REA JET has a complete product range of different laser systems which are even running at high speeds, too. Do you prefer markings via label or ink? No problem, our portfolio comprehends suitable inks and labels technologies as well. Applications Areas of service application
Abrasive
Direct marking of abrasive Grinding and buffing is a science unto itself and a skill too. Just grabbed the wrong grain or buff and all work was in vain. We could already support many polish and buff producers with coding and marking their material. Benefit from our experience! Applications Areas of service application
Wood and Timber
Direct marking of wood and timber The natural material wood always has a beautiful effect on us. However, at some point any board, every chipboard and every laminated wood needs to get produced or processed. Under heaviest conditions. Surfaces and edges need to be marked in spite of dust, head, cold and strands. Reliably, every day. Best-known producers of wooden pallets for the construction industry have been using REA JET technology for years. Why? Because it works! Applications Areas of service application
