PRINTING INKS IN FOOD PACKAGING

  Printing inks on food packaging materials are used for consumer information as well as for marketing purposes. This happens thanks to flexo printing. Flexo printing is a form of printing process which utilizes a flexible relief plate. Flexographic inks are inks transferred by the process of flexography, primarily used in the printing of packaging materials. Set-off of nonvolatile compounds from printing inks in food packaging materials and the role of lacquers to avoid migration; •Set-off during manufacturing and storage affects ink components migration. •Food safety assessment requires migration studies of packaging ink components to food. •24 migrants coming from inks were found in-migration from 2 multilayer materials. •The number of migrants decreased dramatically when an external lacquer was added. •Some new migrants appear by the reaction between ink and lacquer. Inks are widely used in food packaging materials and therefore the transition from ink components to food should be

  WHAT IS 3D PRINTING? 3D printing uses computer-aided design (CAD) to create three-dimensional objects by layering them. 3D printing, sometimes referred to as additive manufacturing , involves layering materials such as plastics, composites, or biomaterials to create objects that differ in shape, size, hardness, and color. 3D printing is useful to architects for creating mockups and to mechanics for creating tools. Three-dimensional printing is inexpensive prosthetics, spare parts, rapid prototyping, creating personalized items, and manufacturing with minimum waste. 3D PRINTING USAGE IN MEDICINE 3D printing in the medical field creates patient-specific organ replicas that surgeons can be used to practice before performing complicated operations. “3D printing can be used to produce prosthetic limbs that are customized.” 3D printing also allows the patient to design a prosthetic that corresponds directly to their needs. For example, Body Labs has created a system that allows patients to

WHAT IS THE LACQUER USED FOR?

  Lacquer is one of the processes applied after printing. It is a frequently preferred method because it provides shine and durability. It adds a visual value to printed products as it gives more shine than varnish applications. The lacquer applied to the printing surface makes the product look brighter and more attractive. It is an application to give and protect the design and aesthetic appearance. The lacquered paper surface is highly resistant to scratches, moisture, sunlight, and the spread of the print on the paper. Compared to other coating methods, the polish gives the brightest appearance. As the thickness of the paper increases, the probability of cracking in the paper increases during the folding, folding, and cutting processes after printing.                                            Over Print Lacquer: Over Print Varnish has been created for the security of printed surfaces.
