PUR Glue for Book Printing Suppliers
Origin:Image Printing  Data: 8/12/2011  Keywords: book printing manufacturers, book printing suppliers, books printing press
PUR glue has been popular in American and European books printing press market for many years, because it has many advantages compared with regular EVA and PVA glues. PUR glue is irreversible cooling type glue, and it is very flexible and soft when book printing suppliers apply to perfect binding books.
The book can be opened in 180 centigrade, and the spine is very flexible and soft. When you open the book and lay it on the desk, it will not rebound back, which is very suitable for textbooks. The students can put some textbooks on desk but not necessary to press it by hand. Many educational institution or councils overseas requires that the textbooks should be bound by PUR glue.
PUR glue is also very good for the paper with high weight, lamination, UV or varnish coating, cross grain etc. This character is extremely attractive to many book printing manufactures in China. Before the people in books printing press room could not use high weight paper as text pages, and they have to consider loose-leaf binding when the text pages are coated or laminated, but now PUR glue can resolve this problem perfectly because PUR glue has very strong and special cohesive force.
PUR glue is also used as basis glue of pre-glued laminator. For this laminator, PUR glue can be coated very thin and little, but the cohesive force still perform very well. Because of much thin glue and high transparent, the color of surface laminated by PUR glue base appears much more shiny and fantastic. Now in China more and more book printing manufactures try to use PUR glue in binding and laminating.
PUR glue is very eco-friendly, when it replace EVA or PVA glues, the oil could be saved much (EVA and PVA come from oil). If PUR glue can take place of regular glues, there will be much more oil saved. So our environment will become much better. In order to achieve eco-friendly aim, many buyers or markets overseas encourage book printing suppliers to use PUR glue.
PUR glue performs very stable. After make strict tests, PUR glue products are able to overcome extremely bad climate including low or high temperatures, heavy humidity and solvent environment. So PUR glue bound books can be used in cold area such as Alaska or Siberia etc. These books can be stored and used frequently with obvious advantages compared with regular glue bound books.
Book printing suppliers will not cost much to expand PUR glue. Even though PUR glue prices are higher than regular glues, the usage is very little than regular glues, so finally total costs will not be increased much. One more extra cost is to upgrade the equipments which are main concerning of most book printing manufactures. Because PUR glue is not very popular in China now, if there are not stable and big order requests, few book printing press room would like to take the risk of upgrading the equipments. But now books printing press association and government are involved in expanding its usage.
