A, lettering on the importance of the product
Normally we always talk about the consumption period of commodity, service life, and about the food safety such as topic, all of these data will be printed to the packaging. Have manufacturer for bearing the product service life, and cause all the goods back to factory, this example illustrates the printing of packaging has a very important role. Many food companies workshop more installed camera sensors to check all the goods, they are willing to consume huge cost to printing.
We often see is used on the packaging gravure and offset printing method to print the name of the manufacturer, name of commodity and composition table. These is called source marking. For consumers, they are deliver goods all kinds of data, and highlight the commodity brand, to increase consumer confidence in goods. In addition, the use of packaging deadline and manufacturers inherent symbols, these are referred to as direct marking, is when the product is the final packing printing, is very important for the safety of products and standard. Past is by printing, inkjet and method such as thermal transfer printing, is now widely used method for laser marking.
Second, the laser printing for packaging
Laser printing technology itself would have on the surface of metal parts and electronic components will be used for cutting surface printing. Able to adapt the packaging use laser printing method, part adopts the method of carbon dioxide gas laser, its main is divided into two kinds, one is the use of laser irradiation light energy will be part of the surface trace text after carbonization, the other is a can in advance will be printed into the field of printing ink layer with the aid of laser cutting, color showing text trace method. These practices is mainly on the resin surface of the carton and thicker, its characteristic is don't need special consumables and reduce operating costs.
There are, however, the problem is, when the irradiation will be part of the surface carbonization, inevitably produce carbon dioxide gas, besides, by cutting cutting when printing will become the dust flying.
In the face of all these problems, at present is to use dust collection machine to deal with, in terms of pharmaceuticals and food packaging, should be conducted in purifying indoor, but market very hope that there is no dust can be developed laser lettering. The stamping method, all printing on the surface, can't denial will lead to printing for friction or dirty content become blurred. Besides, in terms of existing food packaging, the use of plastic flexible packaging is the mainstream, it is likely to damage the packing base material. Described above, therefore, the use of carbide cutting way of laser marking or not very adapt to in using soft packaging of commodities. (Gold Printing Group)
