Introduction to heat transfer printing technology:
With the continuous development of plastic industry in China, each manufacturer has higher and higher requirements on the surface text and text of plastic products.Silk-screen printing, pad printing and other printing methods that used to be widely used have been unable to meet the increasing decorative requirements at present. Therefore, heat transfer printing technology has gradually attracted people's attention.
Heat transfer printing is a new type of packaging technology, which first prints various patterns on the heat transfer film, and then prints the patterns on the surface of the product through the heating process, which can replace screen printing, mobile printing and other processes.Solve the problem of screen printing and pad printing.10 color printing molding, heat transfer film is the heat transfer process must be used up materials, after the transfer of heat transfer technology graphic and text color, adhesion is good, greatly improve the grade and added value of the product.
The use of heat transfer machine and heat transfer film in the plastic surface transfer pattern is already a most basic decoration method.From the 1990s, China's heat transfer printing industry began to sprout, but these heat transfer printing machines have some common characteristics, such as: inconvenient operation, single scope of application and so on.
As we all know, the conventional heat transfer film refers to the pattern with adhesive under the combined action of heat and pressure, together with the protective film can peel off the carrier film, firmly adhere to the surface of the product.Such a process requires that the transfer film has good detachment and thermal continuity, in the process of heat transfer, not only to make the pattern root pine from the carrier film, but also tightly adhere to the surface of the product.Can be loose and tight heat transfer film is an essential feature, but also the key to technology.Through continuous research and practice, technicians have adopted a new type of coating, layer 2 and layer 1.That is, coating directly on the carrier film, achieve one-time coating instead of the detached layer and protective layer, not only solve the problem of tightness, but also shorten the production process, save the cost.
The advantages are:
1, green printing, non-toxic, pollution-free, in line with international non-toxic standards.
2. Eight-color pattern printing can be formed in one time without color registration, which avoids the defects of inaccurate color registration of other technologies.
3, after the transfer of patterns. Text color is clear and natural, bright color, delicate and delicate.
4. Low production consumption and low cost, mass production can better show its characteristics of low cost and high quality.
5, after the transfer of products with clear text and text, wear resistance, washable, can increase the added value of products, improve product grade, enhance market competitiveness.
