How many silk? How much is the cost of plastic bags in supermarkets? Many people are concerned about these problems. Today, the plastic bag factory will explain them to you.
丝是一个长度单位，等于千分之一厘米，塑料袋厂用来衡量塑料袋厚度的单位，测量工具有千分尺、测厚仪。 应该说的是几C吧，C具体代表啥忘了，超市估计一般2C, 1C承受2公斤左右，C是塑料袋厚度单位，一般俗称丝
Silk is a unit of length, equal to one thousandth of a centimeter. Plastic bag factory is used to measure the thickness of plastic bags. The measuring tools are micrometer and thickness gauge. Should say how many C, C specifically represents what forgot, supermarkets estimate that generally 2C, 1C bears about 2 kilograms, C is the thickness unit of plastic bags, commonly known as silk.
Mic is the unit of thickness, 1 wire = 10mic = 0.01mm
Mic is micron and ml is wire
The state stipulates that plastic bags in supermarkets should not be less than 0.025 mm.
There is no uniform standard for the thickness of plastic bags used in supermarkets before the implementation of the plastic restriction order, but most of the plastic shopping bags will not reach 0.025mm (single plastic film), which is called ultra-thin plastic bags, and the reuse rate is low. The plastic restriction order and the plastic shopping bag standard to be implemented on June 1st all stipulate the lower limit of the thickness of plastic bags in supermarkets: the thickness of single plastic film must not be less than 0.025mm, and the plastic bag factory generally requires the thickness above 5 silks to be the standard. Here we need to pay attention to, 5 silk is the lower limit thickness, not the standard thickness.
Supermarket plastic bags are produced and processed with PE as raw material. Supermarket plastic shopping bags are made of HDPE, which is the low-pressure plastic bags mentioned by plastic bags factories. Some bulk food bags and fresh-keeping film are made of LDPE, which is the high-pressure plastic bags often referred to by plastic bags factories. Supermarket plastic bags do not have uniform specifications, so the cost of plastic bags in supermarkets is not very sure. Supermarket plastic shopping bags are made of high density polyethylene, the thickness is generally 1.5-3 wires, 1 wire = 0.01 mm. But one point can be explained to you: the price of plastic bags in supermarkets (one wool, two wool, three wool) is slightly higher than the factory price of plastic bags, higher than the cost price of plastic bags in supermarkets.
