About flexo in flexible packaging in the field of application, people more attention is its feasibility in food flexible packaging, main motive is to consider the consumers most concerned problems, namely the food safety problems.Talking about food safety problems, the most easy is reminiscent of "plasticizer" event.This event was first was found in the food industry in Taiwan, is caused by food packaging residual migration and, later, as the food industry in mainland China also exist this kind of problem.Events, flexible packaging enterprises in mainland China's first reaction was to self checking whether there is a problem, now, many flexible packaging enterprises was talking about "plastic".
The function of food packaging itself is to protect the safety of food, can't, in turn, pollution.Food flexible packaging in the residue mainly comes from the printing and composite process, printing ink, is one of the hidden danger of excessive residue problem, because of the ink used in found in the previous test exists plasticizer.To ensure food safety, golden think the premise is the use of safe, environmental printing ink to printing packaging, and the water-based ink flexo process use is what we have tended to favor.
As everybody knows, flexo ink layer thinner, so its solvent residues will not bring harmful material to packaging especially food packaging migration risk, threat to food security does not exist, so to speak.In addition to security, flexo was in a single or a short in the product.It is well known that long list is gravure expertise, this is the other way than by printing.However, with the diversification of consumer demand on the market at present, many gravure orders frequently redesign is facing, and long single also in gradually reduce, order of less than 10000 meters, if use gravure do in single or a short word, considering the high cost of gravure plate making flexible packaging enterprises, there is no profit space to talk about.And then, the advantages of flexo, because the flexographic plate making the gravure plate making cycle is short, low comprehensive cost more, believe this unique advantage, will make flexo more promising in the field of flexible packaging.
