Current situation and development trend of plastic flexible packaging printing industry

gravure printing is almost equal in publishing and packaging in Europe and the United States. But in China, gravure printing only outshines others in the packaging market. Only solvent based inks accompany. Here we only make a brief analysis of the current situation and development trend of plastic flexible packaging printing and gravure ink

at present, gravure inks on the market are roughly divided into two categories: surface printing inks and internal printing inks. Surface printing ink is mainly used for polyamide based ink of PE film and nitrocellulose based ink of paper. In addition, there are some inks based on chloroacetic resin for aluminum foil printing. The inner printing ink is mainly the chlorinated polypropylene ink used for BOPP film and the polyurethane ink used for pet and NY film

for the whole market in China, the annual consumption of plastic gravure ink is about 100000 tons. Among them, surface printing ink accounts for about 40%, and early printing ink accounts for about 60%. In early printing inks, propylene inks have accounted for 90% of the market share by strengthening the standard of chlorinated polymers and connecting with downstream user industries, while polyurethane inks only account for about 10% of the market share

most gravure inks currently used use benzene solvents. In view of the gradual improvement of people's awareness of environmental protection, the voice for green packaging urea modified phenolic foam is also getting higher and higher, which puts forward new requirements for our packaging and printing industry, and the development and demand of society once again give us new missions and opportunities

"there is a demand, there must be a market" the development trend of gravure ink will also comply with the needs of society, and will develop towards benzene free, light curing and water-based. At present, some technologies are not mature enough. In addition, the transformation of products is a huge system engineering, which requires a lot of technical transformation funds, so it is still in the development and experimental stage

chlorinated polypropylene inner printing ink, which corresponds to the printing of BOPP film, which is the mainstream in the flexible packaging market, is also the variety with the largest market demand at present. From the actual use situation, it is a very mature product on the whole. At present, the main problem is that its solvent residue value is too high to meet the requirements of many current food enterprises; Moreover, a large number of aromatic hydrocarbon (benzene) solvents are used in the printing process, which does not meet the increasingly stringent environmental requirements. So in the long run, this kind of ink is doomed to be eliminated. At present, the main reason why it can survive is its low price

polyurethane ink, although the current share of towel market only accounts for about 10% of the share of internal printing ink. At present, it is not the mainstream of the printing ink market. However, this kind of ink has many advantages, such as good versatility, can be made into single liquid ink through technical efforts, and can also be developed into environmental protection systems, such as benzene free type, alcohol soluble type, etc. However, the price is higher than that of chlorinated Polybrene ink. If the price problem can be solved, the development potential is huge. Such repeated moisture absorption and drying will produce enough shortcomings to be suitable for making low-temperature working parts; Offset the weak fiber matrix combination, resulting in the geographical distribution of the dominant ink is not obvious, and the adaptation area is broad. It is believed that it will bring a change to the production market in recent years
