Science and Technology Expo: application direction of flexible packaging inks

trend 1: generalization the current situation of printing plants is basically that one type of special ink is applied to a film. It is not only complex to use, but also needs to prepare the corresponding diluent, which leads to the doubling of ink inventory. Due to the fierce competition in modern commerce, the speed of product development and packaging change has accelerated. Many packaging and printing plants produce more batches and less production. Film exchange is frequent. If one type of general-purpose ink can be used in all substrate parts, the inventory can be greatly reduced and the operation can be simplified. In Japan and Southeast Asia, Pu general ink is gradually used to print PET/nylon/OPP, and the sales share of PU ink in the whole composite ink has been rising, up to 50% and 90% of 680million packages during the "double 11" period in 2015

flexible packaging printing based on plastic film plays an important role in packaging printing. According to statistics, plastic packaging accounts for 32.5% and 44% of the whole printing industry in some advanced countries in the world. Generally speaking, the single flexible packaging material department has poor protection for the contents, so the composite material department is used more. Its production process is plastic film + gravure/flexo printing composite cutting bag making customers

trend 2: environmental protection

solvents used in ink generally include toluene, ketones, esters, alcohols or water. Relatively speaking, toluene and ketone solvents do great harm to human body. Governments of all countries are formulating or preparing to formulate relevant laws and regulations to enhance the degree of association and dependence between aluminum processing enterprises. Another development trend is: benzene and ketone free toluene

ketone free toluene free and ketone free oil ink based oil plastic ink (only alcohol and lipid ink) because it provides detailed data for people to analyze this, alcohol Ester general-purpose inks, which are universal and environmentally friendly, are the development trend of composite inks. Now Japan has begun to use them in batches, and some multinational companies such as DIC and SICPA are also promoting them
