Vacuum packagingtoprotect the productfromenvironmental pollution,andpackagingtoextendtheshelf lifeoffood, etc.,can improvethevalueandqualityoftheproduct.Since the1940s,vacuumpackaging machinewehave developed rapidly.In people'slivingand work areas,a variety ofplasticvacuumpackagingeverywhere.Lightweight,sealed,preservation,corrosion,rust-proofplasticvacuumpackagingthroughoutfrom food to pharmaceuticals,knitwear,manufacturedfromprecision productstomany other areasofmetalprocessing plantsandlaboratories.Increasingly widespread applicationofvacuum packaging,promotethedevelopmentofplasticvacuum packagingmachines,but also put forwardhigher requirements. Currently, thevacuum packagingtechnology trendsinthe world todayis mainly reflectedinthefollowing aspects: 1,highefficiency:highproductionefficiencyvacuumpackaging machineproduction efficiencyfromthedevelopmentofseveral piecesperminuteto tens. 2automation:rotary vacuum chamberpackaging machinehasavery highdegree of automation,multi-station.The machinefilling and vacuumtwoturntablecomplete for the bags,feeding,fillingpresealingupthepackages sent to thevacuumturntable. 3,thestand-alonemulti-function:a singlemulti-functioncanbeeasilyexpandeduse.Stand-alonemulti-functionalmodulardesign,transformationandcombinationoffunctional modules,differentpackaging materials, packaging materials, packaging requirementsapply todifferent types ofvacuumpackaging machine. 4,the groupwiththeproduction line: the composition oftheproduction linewhena growing number ofrequired functionality,allconcentratedinastand-alonewill makeavery complexstructure,operation and maintenanceisnotconvenient.Then the functionis different fromthecombination of several machinesto matchtheefficiencyofsuccesscan be more completeproduction lines. 5, the use ofnewtechnology:packagingmethods, extensive use ofinflatable packagingtoreplacethevacuum-packed,closely combinetheinflatedingredients,packaging materialsandtheinflatable packaging machinethree;control technology, increased use ofcomputer technologyandmicro-electronic technology;in sealing, theapplication of heat pipesandcold sealing technology.The adoptionofthese new technologies,vacuumpackaging machinesmoreefficientand intelligent.
