What parameters should you pay attention to when purchasing a vertical packaging machine?
2025-04-16
What parameters should you pay attention to when purchasing a vertical packaging machine?
I. Core performance parametersa)Packaging speedBasic models: 20-60 bags/minute (suitable for small and medium production)High-end models: 60-120 bags/minute (need to match the overall efficiency of the production line)Example: Food granule packaging usually requires ≥80 bags/minute, while hardware screw packaging can be relaxed to 40 bags/minute
b)Measuring accuracyConventional requirements: ±1%-1.5% (such as feed, building materials)High-precision requirements: ±0.3%-0.5% (such as medicine, high-end food)Technical comparison: Weighing measurement is more accurate than volume measurement, but the cost increases by 30%-50%
c)Packing size rangeBag width: usually 50-300mm, special models can reach 500mmBag length: needs to adapt to the product height, special-shaped bags require customized molds
II. Functional adaptability parametersa)Material compatibilityParticles/powders: require a vibration plate or a screw propellerLiquids/pastes: require a piston pump or a gear pump systemSpecial requirements: anti-static (electronic components), explosion-proof (chemical) and other designs require additional configurationb)Sealing formThree-side seal: strong versatility, low costFour-side seal: better sealing, suitable for moisture-prone productsBack seal/special-shaped seal: require customized heat sealing mold
c)Control systemBasic type: PLC+touch screen (supports parameter storage)Intelligent type: IoT interface+MES data traceability (suitable for digital factories)
III. Equipment reliability parametersa)Material and structureContact parts: 304 stainless steel (food/pharmaceutical grade)Body strength: carbon steel (general purpose) vs. Aluminum alloy (lightweight)
b)Energy consumption and maintenanceServo motor: 30%-40% more energy-efficient than traditional motorsModular design: Changeover time can be shortened to within 3 minutes
IV. Supplier service parametersa)After-sales responseQuality standards: 48-hour door-to-door service + lifetime technical supportKey accessories: Ensure that there are spare parts in stock locallyb)Compliance certificationFood/pharmaceutical industry: must comply with FDA, GMP and other certificationsExport equipment: CE or UL certification
c)Purchase recommendation processClear requirements: first determine product characteristics (such as particle size, packaging weight) and production targetsField testing: require suppliers to provide prototype test packages (focus on accuracy and stability)Cost accounting: Comprehensively evaluate equipment price, energy consumption, labor savings and after-sales costs

How to choose a packaging machine based on product characteristics? Analysis of 6 core dimensions
2025-04-29
A. Product physical properties
Morphology and size
Particles/powders (such as nuts and milk powder): require a vertical packaging machine, screw metering accuracy of 0.5%-1%, and dust control requires a negative pressure anti-residue design
Liquids (such as juice and cooking oil): plunger or flow meter filling machine, viscosity adaptability is the key
Large items (such as auto parts): horizontal packaging machines support 1.5 meters in length and 50kg in weight
Special needs
Fragile items: require shockproof and cushioning packaging, with a breakage rate of ≤0.3%6
Easily oxidizable foods (such as dried mangoes): vacuum or nitrogen-filled packaging machines are preferred, with residual oxygen content ≤1%
B. Packaging form matching
Packaging type Applicable scenarios Equipment ExamplesVacuum packaging: meat, seafood, dry goods preservation, rolling vacuum machine (automatic correction sealing belt)Heat shrink packaging: cylindrical products (such as beverage bottles), models with imported high-temperature resistant sealing and cutting knivesBag packaging: pre-made bagged granular/block food, models that support ±1% filling accuracy
C. Capacity and AutomationSmall and medium scale: semi-automatic body-fitting vacuum machine (from 8,300 yuan, suitable for experimental production)Large scale: fully automatic stretch film packaging line (from 37,800 yuan, integrated metering and nitrogen filling functions)High flexibility requirements: modular design, switchable packaging specifications (such as heat sealing machine supports Three-side/four-side sealing)
D. Material compatibilityFood-grade contact: 304 stainless steel or Teflon-coated pipes are requiredAluminum foil/composite film: equipped with anti-stick heating hopper
E. Cost and benefitInitial investment: including equipment, installation, training (such as Guchuan Machinery provides full-process services)Long-term return: high-speed machine (300 bags/minute) can reduce labor costs by more than 30%
F. Supplier evaluationTechnical adaptation: customized solution capabilities (non-standard products require special molds)After-sales service: core component warranty (such as heat sealing module ≥ 2 years), fault response time ≤ 24 hours
