Post-press technology innovation will become a hot issue in today's printing and packaging industry

The prepress and printing of the current printing (packing and printing) use computer technology and new equipment to complete the upgrading of production factors. The production efficiency of the product quality has been rapidly improved, and the post-printing processing technology as surface finishing and adhesive molding has fallen behind, and it is no longer suitable for printing. The changes and requirements of technology and printed materials have hampered the development of printing as a whole. This view of post-press technological innovation will become a hot spot in the market. Surface coating film, coating, bronzing, glue forming glue binding, paste box printing and processing will form a new industrial structure of the packaging and printing industry, product structure adjustment and business connotation.

The coating has been improved from the glue-applied wet composite process to the pre-coating dry composite process. In the past two years, a latex-type (water-based glue) wet compounding process was introduced. The formation of a pre-painted film dry composite technology, solvent-type adhesive coating wet composite technology, emulsion type (water-based glue) that is glue wet wet composite process multiple forms of production coexist. It promotes the diversified development of materials such as solvent-free melting hot-melt adhesive pre-coated films, solvent-softening coating-approved coating films, film-covered hot-melt adhesives, solvent-coated adhesives, and emulsion-type (water-based) film-covering adhesives. Shows simple dry laminating machine (electronic laminator), liquid-dynamic infrared dual-cavity oil-temperature efficient laminator, non-heating water-based glue laminating machine, wet-dry laminating machine and many other structures, properties, price-based machinery manufacture. At the same time, new sales groups are formed that are based on certain technologies or are compatible with multiple technologies.

The glazing was rapidly adopted to reduce the cost of surface finishing and eliminate the use of composite films to prevent "white pollution." Apart from UV-type, water-based and other structural differences, glazing coatings also include light, matt, and metallic light, as well as diversified glazing methods for overall glazing and partial glazing, and complete construction development on-line to the press.

Glue-gluing and gluing, etc., bonding and forming processing, and gradually realize mechanization and automation. New production technologies require new materials. Not only the pursuit of initial viscosity is fast and good, but it also requires long-term and effective long-term stability. The diversity of glue-adhesive hot-melt adhesives and box-made adhesives allows users to have more choices. (Extracted from China Packaging Online)
