Self supporting bag manufacturers introduce packaging material knowledge: how much is 1 silk in food packaging bag printing industry?
In the food packaging printing industry, we often hear the saying of how thick the silk is. What is the "silk" here? Specializing in the production of food bags, vacuum packaging bags Dongguan Packaging Co., Ltd. for you to explain.
In the introduction of self-supporting bag manufacturers, the "silk" is a unit of measurement, equal to 0.01 mm, that is, 1 wire = 0.01 mm. In the north, there are also "silk" called "Dao", which are all measurement units. Note that the "silk" here is not the same as the "Silk meter" in the unit of length. Their relationship is 1 mm (mm) = 10 mm (DMM) = 100 Hu meters (CMM, also known as "silk") = 1000 microns (m). www.ycritai.cn/
