Non-woven bag production process introduction
Non-woven bags are generally used screen printing process, which is often referred to as "screen printing", which has been a lot of manufacturers are more commonly used printing process. Generally artificial printing, so the process of color control is not good control, so there are many new non-woven printing methods, where we introduce the current mainstream market several:
However, with the guests on the exquisite product printing and environmental protection requirements continue to rise, emerged many new non-woven printing methods, here we introduce the current mainstream market several:
First, the watermark
Because of its use of water-based elastic mortar as a printing medium named, more common in textile printing, also known as printing. Printing paste and water-based elastic plastic shell to reconcile. Printing plate without chemical solvents, can be washed directly with water. It is characterized by a good tinting strength, with a strong cover and fastness, washable, basically no smell.
Second, gravure printing
Finished products processed in this way are usually called laminating non-woven bags. This process is divided into two steps, that is, the first use of the traditional gravure printing process will be printed on the film, and then use the film coating process will be printed on the composite film on the non-woven fabric. General large-area color pattern printing of non-woven bags are used in this process. It is characterized by beautifully printed, full use of machine production, short production cycle. In addition the product has excellent water resistance, durability of finished products than other non-woven bags good production. Films have two kinds of light and matt to choose from, matte matte effect! The disadvantage is that there are conflicts with the concept of environmental protection, due to the film is difficult to degradation.
Third, thermal transfer
Thermal transfer printing is a special type of printing! This method requires intermediate media, that is, the first graphic printing thermal transfer film or thermal transfer paper, and then transferred by the transfer device to heat the pattern transferred to the non-woven fabric. Medium commonly used in textile printing is thermal transfer film. Its advantages are: beautifully printed, rich level version, comparable to photos. For small area color image printing. The disadvantage is the high price, high printing costs.
