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

How to buy automatic food packaging machine? When purchasing an automatic food packaging machine, you must first consider the customer's packaging product situation, including the size of the food packaging bag, packaging height, and packaging speed requirements. Based on these factors, the specific model to choose is determined.   According to the main structure and configuration components of the small food packaging machine, a high-quality automatic food packaging machine must have the following basic conditions:   1. The PLC control system selected by quality, because the control system is the core control system of the whole machine, whether the goodness of the control system directly affects the stability of the machine and the service life of the machine, therefore, the control system must be able to ensure a good brand, the industry's enterprise products, such as Taiwan imported Taiwan, Japan imported Mitsubishi, imported Siemens and other brands are worth choosing.   2. The electrical components must be selected from standard low-voltage electrical manufacturing enterprises to ensure safety, reliability and durability, because the electrical control part is the brain of the packaging machine. The composition of the control line of the whole machine must ensure the convenience of maintenance and the versatility and standardization of spare parts. It is strictly forbidden to use the old series of electrical switches and other components of the old model system that have been clearly eliminated by the Ministry of Electrical and Mechanical Services (such products reduce the cost of the manufacturer, but increase the trouble for the user).   3. The steel structure of the whole machine must meet the requirements of frequent use from material to thickness, especially the structure and material use of the part in contact with the material must meet the requirements of food-grade hygiene and standard thickness and strength.   4. The appearance design of the whole machine should be reasonable, beautiful, and meet the needs of professional standardized electromechanical products, with basic safety, various prompts in key positions must be complete and obvious signs, the nameplate must indicate the number of equipment, delivery delivery date, technical parameters and implementation standards.   5. The current standard implemented by food packaging machine manufacturers is the GB/T9177-2004 standard. The distinction of machine models is mainly determined according to the width of the sealing bag of the machine. Of course, there are many non-standard models that belong to the special requirements of users. Small bag food packaging machine, automatic food packaging machine, bagged food packaging machine, food packaging machine, automatic particle packaging machine packaging machine.
