The relative humidity of the workshop should be controlled between 50-60% as far as possible, but it should not be too low. When it is lower than 40%, it is easy to produce static electricity. The best temperature is 18 ~ 23 ℃
The effective width of plastic woven bags is poor. Even after China's accession to the WTO for more than ten years, China's exports in important industries are still strong, and the import of plastic industry to the United States is also growing. For the plastic industry practitioners, the growth rate and reasons of export growth are worthy of attention. China's statistics show that the annual growth rate of China's plastic industry is about%, and the annual growth rate is about% %According to the new report "global flexible packaging market outlook" released by a well-known British research company, the global flexible packaging market will maintain a continuous growth rate of% in the next five years, and the annual output value is expected to reach billion US dollars.
Woven bags have a wide range of applications, most of which are used for the whole packaging and packaging of all kinds of goods. They are widely used in industrial chemistry. Plastic woven bags are made of polypropylene resin as the main raw material, extruded and stretched into flat silk, then woven and bagged. Composite plastic woven bags are made of plastic woven cloth as the base material and compounded by tape casting For example, the plastic products imported from China increased by more than% in - years include vinyl chloride polymer, vinyl acetate polymer, amino resin, phenolic resin and polyurethane, primary form silicone, cellulose and its chemical derivatives, as well as pipe, pipe and hose accessories.
With the continuous development and progress of the times, some novel scientific and technological inventions are constantly pouring out. Have you ever heard of the more popular ones? Nowadays, there are all kinds of plastic woven bags, and the printing process is also gradually improving, which can be said to be more and more extensive. There are many kinds of printing processes for plastic woven bags, including silk screen printing, machine printing, heat transfer printing, film covered color printing, etc. they all have their own characteristics, but also have their own advantages and disadvantages.
