Sometimes when we store food or clothes, we use vacuum bags to ensure that the food does not deteriorate or the clothes are better stored. The vacuum bag sucks away excess air, saves storage air, isolates microorganisms in the air, and can effectively prevent mold and moisture. But when we buy a vacuum bag, we will see the size or quantity of the filament. what does this number mean ?What does the wire count of the vacuum bag mean?The wire number of the vacuum bag refers to the thickness of the vacuum bag.”Silk”the larger the number,The thicker the vacuum bag. The unit of silk is one thousandth, that is,0.01mm,1mm=10Simi. Therefore, how many wires there are in the vacuum packaging bag means that its thickness is a few tenths of a millimeter. for example8Silk is0.08mm thick,11Silk is0.11mm. It should be noted that the number of filaments of vacuum bags usually refers to the thickness of one side, but there are also many buyers who will mark the thickness of double layers, such as14Silk,18Silk,twenty twoSilk, pay attention to the distinction when buying.vacuum bag16Silk refers to the thickness of the vacuum packaging bag is0.16mm.vacuum bagtwenty fourSilk refers to the thickness of the vacuum packaging bag is0.24mm.vacuum bag32Silk refers to the thickness of the vacuum packaging bag is0.32mm.silk is machinist0.01Commonly known as mm, in the north put0.01expressed in millimeters”road”many. The unit of silk is one-thousandth, and it can only be measured by vernier calipers, micrometers, and smaller block gauges.How much silk does the vacuum bag buy?Vacuum packaging bags are not as thick as possible, thicker ones are more wear-resistant, and thinner ones are more flexible, depending on what you need. Usually a single side thickness is chosen7-8Silky, this kind of thickness is moderate. common vacuum bags”Wire count”Yes6-11silk, the thickest11Silky.Recommended related articles: Can vacuum food bags be reused?Relevant knowledge developmentPEvacuum bag andPPVacuum bags are an important part of vacuum bag products, and the differences between the two mainly include the following aspects.First,PEvacuum bag withPPThe chemical structure of vacuum bags is different.PEThat is, polyethylene is a polymer with a simple structure consisting of repeated-CH2-Units are connected, and polyethylene is formed by addition polymerization of ethylene.PPRefers to polypropylene, which is a semi-crystalline thermoplastic.two,PEvacuum bag withPPThe characteristics of vacuum bags are different.Polyethylene is odorless, non-toxic, feels like wax, and has excellent low temperature resistance.PEThe minimum operating temperature of the vacuum bag can reach-70~-100℃. Polyethylene has good chemical stability and can withstand most acid and alkali erosions. It is insoluble in common solvents at room temperature, has low water absorption, and has excellent electrical insulation properties. However, polyethylene has poor heat aging resistance. Polypropylene has high impact resistance, strong mechanical properties, and can resist various organic solvents and acid and alkali corrosion.
