1, packaging machine material directly affects the quality of its stand or fall, most manufacturers are said to be made of stainless steel, but stainless steel is also divided into several kinds, take 201 stainless steel and 304 stainless steel: 201 is high manganese, the surface is very bright with dark black bright, high manganese is easy to rust.304 contains more chromium, the surface appears matte and does not rust. Put the two together and there will be a comparison.The most important difference is that the corrosion resistance of 201 is very poor, so the price is much cheaper. And because 201 contains low nickel, the price is lower than 304, so the corrosion resistance is not as good as 304.So the vacuum packaging machine steel plate is 304 steel plate is good, especially the vacuum chamber.
2, as the heart of vacuum packaging machine, vacuum pump plays a crucial role in the quality of vacuum packaging machine, so the use of brand vacuum pump is essential, so as to ensure the quality of packaging machine.
3. Check whether the function of vacuum packaging machine is consistent with the instructions, whether it is more convenient and humanized to operate, and whether the equipment is easy to operate because of its multiple functions, which is generally convenient for daily maintenance and good quality.
4, configuration is the normal use of the packaging machine link, high configuration can not only improve the overall performance of the packaging machine, use time is long.
