When purchasing fully automatic packaging machines from China, it is recommended to evaluate them from several key dimensions, including technology, supply chain, price, after-sales service, and risk control. Below is a comprehensive checklist of considerations, which can be used directly for price inquiries, supplier screening, or factory visits:
✅ I. Clarify Required Parameters
Before communicating with manufacturers, be sure to clearly define your needs; otherwise, you may be recommended unsuitable models.
1. Packaging Machine Types and Functions
Pillow-type packaging machine, vertical automatic packaging machine, granulator machine, powder machine, liquid packaging machine, etc.
Is automatic feeding, weighing, automatic labeling, and rejection required?
2. Packaging Materials
Plastic film, aluminum foil, composite film, paper-plastic, etc.
Is vacuum sealing, gas filling (modified atmosphere packaging), or heat sealing (pulse/constant temperature) required?
3. Product Characteristics
Flowability (granules/powders/liquids/pastes)
Is it fragile, hygroscopic, or oily?
4. Packaging Specifications
Bag type (back seal/three-side seal/four-side seal/stand-up pouch)
Speed (bags/minute)
Accuracy (± grams)
✅ II. Points to Note When Choosing a Reliable Supplier
1. Check if they have an actual factory; avoid shell companies.
Ask them to provide factory videos, live streams, or conduct an on-site factory visit.
Check if the business license matches the factory address.
Companies named "XX Machinery Equipment Co., Ltd." are usually more reliable than trading companies.
2. 1. Review Experience
Are there similar industry case studies?
Factory primarily targeting overseas markets (export-oriented factories) usually have better packaging machine stability, documentation, and export experience.
3. Inquire about core component brands
These determine machine stability and lifespan. It's recommended to confirm they are original and genuine:
PLC control system: Mitsubishi / Siemens / Omron
Servo motor: Panasonic / Yaskawa
Sensor/Photoelectric: Keyence / SICK
Pneumatic components: Airtac / SMC / FESTO
Vacuum pump: BUSCH (high-end) / Domestic brands are also acceptable
Low-priced machines often use generic components, which significantly increases the failure rate.
✅ III. Price Structure Transparency
Packaging machine prices in China vary considerably. The main factors to consider are:
1. Does it include the following items:
Automatic feeding device?
Coding machine/inkjet printer?
Multi-head scale?
Modified atmosphere system?
1. Stainless steel type (food-grade 304SS or the cheaper 201SS?)
2. Beware of the "low price attraction + later price increase" trap. The quotation must clearly specify all configurations, brands, and warranty details.
✅ IV. Confirm After-Sales and Technical Support
Especially for exports, pay close attention to:
1. Are English user manuals, wiring diagrams, exploded views, and maintenance guides provided?
2. How long is the warranty period? How are critical components handled?
Commonly mentioned:
1-year warranty on the whole machine
Wearings of vulnerable parts are not covered
Overseas after-sales service typically includes remote guidance and parts shipping
3. Does it support video guidance, remote debugging, and TeamViewer parameter adjustment?
✅ V. Stability Inspection of Packaging Machine
1. If machine inspection is possible, it is recommended to check:
2. Whether the operating speed meets the standard
3. Whether bag jamming, leaks, or large errors occur after running for more than 1 hour
4. Whether the seal is firm and flat
5. Whether the film positioning and cutter position are stable
6. Whether the packaging weight maintains accuracy at high speeds
7. Whether the noise and horizontal vibration are abnormal
8. Material and wear condition of vulnerable parts
✅ VI. Acceptance and Shipping Precautions
1. Clarify in advance: Customer sample test video
2. Request a sample of the final packaging effect
3. Whether the packaging machine has undergone durability testing
4. Whether the wooden crate export packaging meets international transportation standards
✅ VII. International Shipping and Customs Clearance
If you are located overseas, you need to confirm:
Volume/Weight (choose sea, air, or rail freight)
Whether CE or UL certificates are available (if required by your country)
Whether the HS Code matches local customs regulations
Whether the factory has export experience (important!)
✅ VIII. Payment Method Risk Control
We recommend Alibaba Escrow/Bank Letter of Credit/Phased Payment
Avoid full payment upfront (especially if no factory inspection is required).
Common method:
30% prepayment + 70% payment after inspection before shipment
