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
