The varnishing process is a technique used to protect and enhance the gloss of printed materials, suitable for paper prints or cardboard, among others. Currently, varnishing techniques are increasingly adopted …
As modern printing enterprises continuously improve production efficiency, bearings, as crucial rotating core components in printing equipment, are prone to varying degrees of damage during long-term high-speed operation. Failure to …
The batch number on packaging bags provides crucial information about the product’s processing, allowing for the determination of the product’s warranty period and ensuring good traceability. This serves as an …
Common conductive ink printing techniques can be divided into contact and non-contact categories. Contact printing includes gravure printing, flexographic printing, and screen printing, while non-contact printing includes inkjet printing, electrohydrodynamic …
Composition of Conductive Ink：Conductive ink is a type of ink applied to substrates to provide the ability to conduct current and eliminate accumulated static charges. It is composed of conductive …
“Smart color-changing packaging” refers to packaging that can respond to environmental factors such as light, temperature, and humidity by changing color. This feature is used for various functions, including anti-counterfeiting, …
Ink is composed of pigments, solvents, binders, and other additives. Among these, the binder significantly impacts the ink’s rheology, viscosity, fineness, and printability. Traditional ink binders typically use highly toxic …
The phenomenon of adhesion between polymer films and metal has been a focal point of research for scholars. To date, four adhesive mechanisms for metal film coating, namely mechanical interlocking …
During the production and processing of film-coated products, parameters such as heating temperature and rate, cooling temperature, lamination pressure, drying temperature, as well as material pretreatment and post-printing processes, have …
During the coating process, it is essential to ensure that polymer films exhibit excellent formability. Polymers need to possess good thermoplastic adhesion to prevent cracking during high-temperature sterilization and curing …
