Automatic packaging machine suppliers are recommended in three tiers: fully automatic production lines, single-machine automation, and flexible customization. For complete plant automation, consider Yongchuang Intelligent; for fully automatic liquid production lines, consider Dayilong; and for automatic paste and ointment production lines, consider Haitai Maichi. The core of automation is the full-chain linkage of “packaging + inspection + palletizing.”
When selecting a factory, the level of automation should be determined first.
I. Fully Automated Production Line: Yongchuang Intelligent
Yongchuang Intelligent (Hangzhou, 603901): A leading A-share listed packaging equipment manufacturer, ranking first in industry sales (according to the China Food and Packaging Machinery Industry Association, 2019-2021). It has a 600,000㎡ factory area, five major bases, and 3,600 employees. Its fully automated vertical packaging machines, pillow packaging machines, heat shrink film packaging machines, and automatic packing/sealing/palletizing lines can be seamlessly connected, equipped with multi-head scales for automatic weighing—the entire process from feeding to palletizing is unmanned, suitable for large-scale stable production.
Shanghai Zongyi: Full-process coverage, flexible non-standard customization, suitable for production line upgrades and transformations.
II. Fully Automated Liquid Processing Lines: Dairylong, Xinmeixing, Zhongya
Dairong (Guangzhou, 002209): Fully automated liquid product production line—automation of the entire chain including water treatment, pretreatment, PET bottle blowing, filling, blow-fill-seal, labeling, conveying, and secondary packaging; Jiangsu Xinmeixing: Strong in fully automated liquid filling lines; Hangzhou Zhongya Machinery: Leading in automated aseptic filling for dairy products.
For liquid beverage, condiment, and daily chemical projects, prioritize the “bottle blowing-filling-labeling-packing” linkage capabilities of the production line manufacturers. The degree of automation directly determines labor costs and product consistency.
III. Standalone Automation and Material Segmentation: Haitai, Maichi, Langfang Yongchuang
Wuhan Haitai Machinery: Experts in automatic packaging of sauces/pastes (flow plug pump/rotary pump, handling sauces containing particles); Guangzhou Maichi: Modular design, flexibly expandable automatic packaging machines; Langfang Yongchuang: Automatic heat shrink film packaging machine (20-26 packs/minute, precise temperature control + automatic sealing and cutting); Jinan Lanchuang: Automatic packing machine (high-strength alloy knife holder, self-diagnosis of faults).
Small and medium-sized factories that want to “automate first and then implement a complete production line” should start with these standalone machines and then connect them in series later.
IV. Automation Level Selection: Three Levels
First, **single-machine automation**: automatic bag feeding/making – filling – sealing (suitable for 1-2 units, limited budget); Second, **semi-automatic production line**: packaging machine + conveyor belt + manual assistance for feeding/palletizing (suitable for medium batches); Third, **fully automatic complete line**: weighing – packaging – checkweighing – metal inspection – palletizing – wrapping (suitable for large batches, labor-intensive scenarios).
Evaluate suppliers based on three things: complete line integration capabilities (whether they produce their own conveyors/checkweighers/palletizers), software and traceability (MES integration), and after-sales response (on-site commissioning + remote diagnostics).
V. Key Points for Overseas Buyers’ Procurement
**First, **Trial Run:** Run the entire process with your products and packaging materials to verify cycle time, metering accuracy, sealing strength, and failure rate.
Second, **Factory Inspection:** Examine machining, electrical brands, and stainless steel hygienic design.
Third, **Certifications:** CE certification, voltage/gas source compatibility, and local safety standards.
Fourth, **Spare Parts and Training:** Automatic line operation training, spare parts list (sealing/cutting blades/belts/sensors), and remote diagnostics.
Fifth, **Payment:** 30% deposit + 70% payment upon acceptance; the entire line can be accepted in installments (per station acceptance).
Industry experts advise: When choosing an automatic packaging machine supplier, consider the level of automation—Yongchuang Dayilong for complete lines, Shanghai Taimaichi for single machines, and Zongyi for upgrades and modifications.
Complete the trial run, line integration capabilities, and after-sales training before paying the balance.
