Why do vacuum packaging bags leak after a period of use?

TheĀ threeĀ commonĀ causesĀ ofĀ airĀ leakageĀ inĀ vacuumĀ packagingĀ bagsĀ areĀ delaminationĀ ofĀ theĀ heat-sealĀ layer,Ā punctureĀ ofĀ theĀ bagĀ byĀ sharpĀ objects,Ā andĀ respirationĀ ofĀ theĀ packagedĀ productĀ itself.Ā Therefore,Ā itĀ isĀ alsoĀ necessaryĀ toĀ startĀ fromĀ theseĀ threeĀ aspectsĀ andĀ exploreĀ preventiveĀ measures.

Ā 

First,Ā chooseĀ theĀ appropriateĀ thickness.Ā VacuumĀ packagingĀ needsĀ toĀ beĀ ofĀ appropriateĀ thickness.Ā AĀ vacuumĀ bagĀ thatĀ isĀ tooĀ thinĀ isĀ easyĀ toĀ beĀ punctured,Ā andĀ aĀ vacuumĀ bagĀ thatĀ isĀ tooĀ thickĀ isĀ notĀ easyĀ toĀ sealĀ afterĀ vacuuming.Ā ThisĀ problemĀ isĀ moreĀ obviousĀ onĀ someĀ smallĀ householdĀ vacuumĀ machines.Ā InĀ eitherĀ case,Ā itĀ willĀ causeĀ theĀ vacuumĀ packagingĀ bagĀ toĀ loseĀ itsĀ function.Ā Therefore,Ā itĀ isĀ recommendedĀ toĀ chooseĀ aĀ largerĀ packagingĀ bagĀ manufacturer.Ā TheyĀ areĀ moreĀ skilledĀ inĀ makingĀ vacuumĀ packagingĀ bagsĀ andĀ canĀ avoidĀ thisĀ problemĀ toĀ aĀ largeĀ extent.

Ā 

Ā 

Ā 

Second,Ā chooseĀ theĀ appropriateĀ heatĀ sealĀ strength.Ā WhenĀ heatĀ sealing,Ā itĀ isĀ necessaryĀ toĀ setĀ reasonableĀ heatĀ sealingĀ parametersĀ accordingĀ toĀ theĀ thickness,Ā size,Ā use,Ā material,Ā etc.Ā ofĀ theĀ vacuumĀ packagingĀ bag,Ā soĀ asĀ toĀ ensureĀ theĀ effectĀ afterĀ vacuuming.Ā Therefore,Ā itĀ isĀ recommendedĀ toĀ chooseĀ aĀ factoryĀ withĀ large-scaleĀ vacuumĀ productionĀ machineryĀ toĀ provideĀ guaranteeĀ forĀ theĀ qualityĀ ofĀ vacuumĀ packagingĀ bagsĀ onĀ theĀ equipment.

Ā 

Again,Ā strengthenĀ theĀ protectionĀ duringĀ transportation.Ā NowĀ thatĀ theĀ logisticsĀ industryĀ isĀ developed,Ā manyĀ productsĀ needĀ toĀ goĀ throughĀ long-distanceĀ transportationĀ beforeĀ theyĀ canĀ enterĀ variousĀ salesĀ points.Ā DuringĀ theĀ transportationĀ process,Ā theĀ vacuumĀ packagingĀ bagĀ mayĀ experienceĀ extrusion,Ā collision,Ā friction,Ā orĀ beĀ piercedĀ byĀ sharpĀ objects.Ā Therefore,Ā itĀ isĀ recommendedĀ toĀ maintainĀ aĀ cleanĀ andĀ stableĀ environmentĀ duringĀ transportationĀ toĀ avoidĀ theĀ vacuumĀ packagingĀ bagĀ beingĀ punctured.

Ā 

Ā 

Ā 

Finally,Ā avoidĀ packingĀ itemsĀ likeĀ seeds.Ā TheĀ importantĀ featureĀ ofĀ vacuumĀ packagingĀ isĀ toĀ dischargeĀ oxygen,Ā butĀ someĀ foodsĀ thatĀ canĀ breathe,Ā suchĀ asĀ plantĀ seeds,Ā plantĀ roots,Ā etc.,Ā oftenĀ undergoĀ respirationĀ duringĀ storage.Ā .Ā TheĀ principleĀ isĀ similarĀ forĀ rootsĀ andĀ tubers.Ā SomeĀ plantĀ rootĀ pickledĀ foods,Ā suchĀ asĀ pickledĀ mustard,Ā theĀ gingerĀ inĀ theĀ foodĀ isĀ notĀ pickled,Ā theĀ cellsĀ areĀ stillĀ alive,Ā andĀ theyĀ willĀ alsoĀ undergoĀ respiration,Ā resultingĀ inĀ swelling.Ā ThereforeĀ vacuumĀ packagingĀ isĀ notĀ recommended.
