Study of PLA Printability with Flexography Ink: Comparison with Common Packaging Polymer
Today, the economic consumption of biodegradable polymers is of capital importance in many applications. One of the most commonly used biopolymers is polylactic acid (PLA). The printability of the biodegradable film has not been fully investigated. This work tested the printability of polylactic acid (PLA) films and compared the print qualities to common packaging films like low density pol...
متن کاملVOC level control by ventilation improvement of Flexography printing room using CFD modeling
Using Computational Fluid Dynamics (CFD) technique, the dispersion contours and the exposure rate of Flexographic printing workers to VOCs in a printing department is evaluated. Firstly, VOCs distribution is determined in the printing room due to the existing ventilation system. Through next steps, 4 scenarios for lowering VOCs concentration and its exposure rate to workers are analyzed. Concen...
متن کاملA Study of PLA Printability with Flexography
Biodegradable films have been introduced in the packaging industry recently. Most products are boxes, bottles and bags. The printability of biodegradable film has not been fully investigated. This study tested the printability on clear and white Polylactic acid (PLA) films, and compared the print qualities to common packaging films like Polypropylene (PP), Polyethylene terephthalate (PET). Wate...
متن کاملPreparation of Reversible Thermochromic Ink for Flexography Printing on Paper and Study its Colorimetric Properties
Thermochromic printing inks could be security inks which respond to the color change when are being exposed to different temperatures. These inks with unusual chemical and physical specific characteristics are mostly produced for flexographic, screen and rotogravure printing systems under the supervision of skilled technical experts and with precise security controls. Since flexographic thermoc...
متن کاملFabrication of large-area stamps, moulds, and conformable photomasks for soft lithography
Low-cost fabrication is essential to the successful introduction of organic electronics and reel-to-reel manufacturing processes. Here it is proposed that extending flexography into the micrometre-size resolution regime may provide an economical commercialization path for plastic devices. Flexography is a high-speed technique commonly used for printing onto very large-area flexible substrates. ...
متن کاملUltrathin high-resolution flexographic printing using nanoporous stamps
Since its invention in ancient times, relief printing, commonly called flexography, has been used to mass-produce artifacts ranging from decorative graphics to printed media. Now, higher-resolution flexography is essential to manufacturing low-cost, large-area printed electronics. However, because of contact-mediated liquid instabilities and spreading, the resolution of flexographic printing us...
