On June 1st, according to U.S. media reports, after U.S. officials discovered a 32-hectare GM wheat field in Oregon recently, Japanese and South Korean officials have suspended imports of U.S. wheat. A Korean food safety official said on May 31 that if GM wheat is found, it will be prohibited from selling in Korea. The report said that how this kind of wheat is planted in Oregon's farmland is still a mystery. This line of wheat, developed by the US Monsanto Agricultural Products Company, is able to withstand the wheat rust remover called ROUNDUP. However, the field experiment was stopped nine years ago. The United States did not approve any commercial planting of genetically modified wheat. Planting genetically modified corn and soybeans is very common, but it is mainly for livestock breeding. At the same time, the European Union stated that it has requested relevant experiments, and the European Union is requesting the inspection of wheat exported to the EU's 27 member states. To ensure that the European continent’s “zero tolerance†policy on genetically modified crops is implemented. (Older)
Two major commercial bookbinding techniques are used today: traditional and perfect binding (or adhesive binding).
Many variations exist for each of these techniques as well.
Traditional binding is generally used on hardcover, or hardbound, books. However, perfect binding (developed originally for paperback books) is being used widely as more durable adhesives are being developed.
In reality, perfect binding is one of many forms of adhesive binding.
It makes books more beautiful.
It can be used for copperplate paper 250g/m2
