    Sustainability in the print and packaging industry
    (2023-07-01) TUTAK, DOĞAN; AYDEMİR, CEM; YENİDOĞAN, SEMİHA; Tutak D., Aydemir C., Yenidoğan S.
    In the printing and packaging industry, sustainability is defined as manufacture and practices that reflect responsibility for the environment and resources to meet the needs and expectations of future generations. In this article, raw material management, cellulose resources, industrial forests, ecological and renewable alternative fiber resources were examined in the framework of the sustainability of the printing and packaging industry. The recycling of printed materials and packaging and the effects of paper-ink types and product design in this recycling have been discussed. The effect of separation and processing at the source on the efficiency of paper recycling, economy and ecology was emphasized. The greenhouse gas emissions of solvents used in inks and cleaners, the impact on climate change, water footprint and carbon footprint issues were examined. Suggestions have been made on environmental sustainability in the printing industry, what needs to be done for a competitive production, successful optimization, minimization of waste, use of existing possibilities, recycling and evaluation of alternatives and use of clean energy.

    Effect of coating pigment type on paper printability with water-based inks
    (2022-07-01) ÖZCAN, ARİF; SÖNMEZ, SİNAN; TUTAK, DOĞAN; ÖZCAN A., SÖNMEZ S., TUTAK D.
    Nowadays, the need for papers and cardboards with improved surface properties is increasing with the development of the packaging industry. The improvements made are not only limited to the paper and paper surface, but also environmentalist approaches are exhibited in printing ink. For this purpose, the use of water-based ink tends to become widespread, especially in food packaging. In this study, five different paper coating formulations were prepared using different proportions of precipitated calcium carbonate (PCC) and kaolin pigments. Latex (Acronal S360D) was used as a binder. All prepared coating mixes were applied onto the base paper surface. All coated papers were also subjected to the calendering process. In addition, three different dyestuffs (14, 17, 20%) concentrations of water-based printing inks were prepared. Prints were made by the silk screen printing technique on the calendered-coated papers. The optical and physical properties (roughness, air permeance, paper gloss and printing gloss, contact angle and surface energy) of all papers were measured according to the standards. Paper gloss, print gloss, Delta E-00 color differences, contact angles and surface energy measurements were made, and the effects of dye ratio on printing and gloss in water-based inks and coating type suitable for printability were investigated. As a result, papers can be coated and even calendered to achieve better paper surface properties and printability. In the case of printing with water-based inks, better printability properties are obtained by choosing PCC pigmented coated papers.
