Ink used in food packaging printing graphic,it's one of the most important factors that affect the safety of packaging food,as a new environmentally friendly printing ink,UV-curable inkjet ink has attracted much attention in the application of food packaging printing .The pros and cons of performance of UV ink's color paste is the key to the preparation of UV inkjet ink.In order to prepare UV inkjet magenta ink's color paste with good dispersion,design formulation experiment for monomers in UV ink's paste,determine the monomer type and content,by changing the ratio of pigment to resin and milling time as well as the kind and the content of dispersants to prepare based ink, by testing the diameter size to evaluate dispersion of UV ink's paste.It has been proved that the monomer type and content is the key factor that influences the dispersion property of UV ink's based ink. The dispersion property of the resin to pigment depends on a great extent on the ratio of resin to pigment,milling time also play an important role. The result also proved that different kind of dispersants and content are also important factors that influence the dispersion property.

The food packaging sector generates large volumes of plastic waste due to the high demand for packaged products with a short shelf-life. Biopolymers such as starch-based materials are a promising alternative to non-renewable resins, offering a sustainable and environmentally friendly food packaging alternative for single-use products. This article provides a chronology of the development of starch-based materials for food packaging. Particular emphasis is placed on the challenges faced in processing these materials using conventional processing techniques for thermoplastics and other emerging techniques such as electrospinning and 3D printing. The improvement of the performance of starch-based materials by blending with other biopolymers, use of micro- and nano-sized reinforcements, and chemical modification of starch is discussed. Finally, an overview of recent developments of these materials in smart food packaging is given.

This paper highlights the possible combination of technologies such as thick film screen printing, ink jet, and post-firing thin film processes in conjunction with laser-drilled fine vias to produce high-density, miniaturized LTCC substrates. To obtain the silver pattern on the inner layers, both conventional thick film printing and ink jet printing (using nano silver particle dispersed ink) were applied on the ceramic green sheets. The ink jet process made it possible to metallize fine lines with line/space = 30/30 μm. For interlayer connections, fine vias of 30 μm in diameter formed by UV laser were used. Then these sheets were stacked on top of each other and fired to obtain a base substrate. On this base substrate, fine copper patterns for flip chip mounting were formed by a thin film process. The surface finish consisted of a nickel passivation and a gold layer deposited by electroless plating. The combination of the three patterning processes for conducting traces and UV laser drilling of fine vias make it appear possible to realize fine pitch LTCC, for example, for flip chip device mounting.

Attention to environmental problems and the importance of maintaining it have caused the researchers to pay more attention in this regard. The production of polymers and resins has increased in recent years and has affected by environmental pollution due to their long-term degradation. An appropriate solution to this problem is the synthesis of degradable and environmentally friendly polymers and resins. Using natural materials in the synthesis of polymers and resins can help them to be environmentally friendly. The purpose of this research is to synthesize urethane acrylate resins using natural resources. For this purpose, the urethane acrylate pre-polymer was synthesized with castor oil. Then, using modified zinc oxide nanoparticles with 1, 3 and 5 wt% urethane acrylate zinc oxide nanocomposites were produced. The use of castor oil as a degradable part and lack of organic solvent in radiation systems led to the creation of an environmentally friendly resin. Subsequently, the viscoelastic behavior of the prepared nanocomposite was evaluated. Spectrometry results confirm the synthesized resin structure. The morphology of nanocomposites confirmed the proper particle size distribution in a 3 wt.% sample. The results of the dynamic mechanical thermal analysis test showed that increasing the amount of modified nano ZnO could increase the glass transition temperature, and the maximum value was observed in 5 wt.% modified nano ZnO (69.7℃).

Water-based UV-curable prepolymers are novel environmentally friendly materials. The blending property of two kinds of the prepolymers, water-based UV-curable polyurethane acrylate (UVPU) and water-based UV-curable epoxy acrylate (WEA), was studied in this paper. Blending compatibility, curing rate, optical and mechanical properties, and the cross-section morphology of the cured films of UVPU and WEA were investigated by Fourier transform infrared (FTIR), UV-visible spectrophotometer (UV-vis) and Environmental scanning electron microscopy (ESEM). Results indicated that the two prepolymers had good blending compatibility and high curing rate under UV radiation. The elongation at break of the cured film by WEA mixed with 20 wt% UVPU had 1.5 times increase compared to pure WEA, and the gloss increased 23% compared to pure UVPU, but the tensile strength decreased slightly. The morphology showed that the molecules of the two prepolymers polymerized each other and formed a network similar to the structure of Interpenetrating Polymer Networks (IPN). The comprehensive properties of the film were improved by blending of WEA and UVPU, and could be widely applied in the fields of coating varnish or printing ink.
