The application and unique advantages of flexo printing in the field of flexible packaging

Throughout the current situation of flexo printing in the flexible packaging market in Europe and America, in the Americas, flexo printing accounts for about 80% of the flexible packaging market, and in Europe has accounted for about 60%. However, in Asia, especially in China's flexible packaging market, flexo printing only accounts for a small amount, and it is currently limited to some surface printing that involves packaging of personal hygiene products such as film materials. However, in recent years, with the gradual recognition of flexo printing in China, it has gradually been accepted by the Chinese due to its advantages of environmental protection and safety.

Over the years, gravure printing has been in the forefront of China's flexible packaging market, which is also inseparable from its superior congenital conditions, such as mature equipment performance, mature professional plate matching facilities and low price, abundant talents, and exquisite printing quality. These conditions are also the main factors that cause the current flexographic printing in China's flexible packaging market can not compete with gravure printing.

In recent years, with the continuous improvement of the degree of intelligence of flexo printing equipment, the dependence on the experience and skills of operators has gradually decreased. This is an important breakthrough in promoting the development of flexo printing in China's flexible packaging market.

Flexo printing is a recognized green process, mainly because it uses water-based or alcohol-soluble ink, and the ink layer is thin, the amount of ink used is about half of gravure printing, reducing the risk of solvent residues, in line with environmental protection concepts. Especially in recent years, the problem of adhesion of water-based inks on film materials is gradually being solved, and the promotion and application of flexo printing in the field of flexible packaging will be easier to achieve. China's flexible packaging companies are paying more attention to flexo printing. Some flexible packaging companies have even begun to use flexo printing. I believe this is also a good start for flexo to better serve flexible packaging.

Flexo has unique advantages in mid and short orders

Regarding the application of flexo printing in the field of flexible packaging, it is mainly the feasibility of flexible packaging of food. The main starting point is to consider the current consumer's most concern, that is, food safety. Speaking of food safety issues, the most reminiscent is the "plasticizer" incident. This incident was first detected in the Taiwanese food industry and was caused by the migration of food packaging residues. Later, it was also found that the food industry in China also had this problem. As soon as the incident came out, the first reaction of mainland flexible packaging companies was to quickly check whether there was a problem. Nowadays, many flexible packaging companies are really talking about "plastic" discoloration.

The function of food packaging itself is to protect the safety of food, and it cannot be contaminated in turn. The residues in food flexible packaging mainly come from printing and compounding processes, and ink is one of the hidden dangers that cause residues to exceed the standard. Because the plastics are indeed found in the inks used in previous tests. To ensure food safety, I think the premise is to use safe and environmentally friendly inks to print food packaging, and the water-based inks used in the flexo process are my favorite.

As everyone knows, the ink layer of flexo printing is relatively thin, so the residual amount of solvent will not bring the risk of migration of harmful substances to the packaging, especially food packaging.

In addition to safety, flexo printing has advantages in making mid-single and short-single products. As we all know, making long forms is the specialty of gravure printing, which is unmatched by other printing methods. However, with the diversification of consumer demand in the current market, many gravure orders are facing the problem of frequent revision, and long orders are also gradually decreasing. Orders below 10,000 meters are everywhere. If gravure printing is used, If you make mid-term or short-term orders, flexible packaging companies will have no room for profit considering the high gravure plate-making costs. At this time, the advantages of flexo printing can be reflected, because the flexographic plate making cycle is shorter than the gravure plate making, and the overall cost is lower. I believe this unique advantage will make flexo printing more effective in China's flexible packaging field.
