Automatic Liquid Sachet Packing Machine Price
Tuesday May-12 2026 18:10:25
Automatic liquid sachet packing machines vary significantly across different production lines, with prices for the same type of machine often ranging from $360 to over $9,500. A key factor influencing price is packing speed; for example, a small model with 30–50 sachets per minute differs drastically from a multi-channel model with 120–200 sachets per minute in motor configuration, feeding structure, and control system. Machines designed for small-batch prototyping by startups or labs range in price from USD 2,800 to 6,500; medium-capacity machines are typically USD 7,000–15,000; and high-speed multi-lane machines can sometimes exceed USD 18,000. These differences in configuration directly impact filling stability and continuous operating time. For instance, some lower-spec models need to slow down when handling high-viscosity liquids, while higher-spec models are equipped with independent heating or stirring modules.
Reasons Affecting Price
The price differences in automatic liquid sachet packing machines are not only due to speed but also related to the choice of internal structure.
The level of automation affects the overall machine logic. For example, semi-automatic models still require manual feeding, while fully automated models use PLC touchscreen control, allowing parameter switching between different liquids.
Increasing packaging speed increases the number of servo motors and the complexity of the traction mechanism, both of which increase costs.
Filling accuracy is determined by the structure of the metering pump or piston pump. Some models employ multi-head synchronous filling designs, reducing downtime when processing honey or syrup.
Regarding materials, most equipment uses a 304 or 316L stainless steel welded frame, but the surface treatment varies. Some use mirror polishing, while others use seamless bending structures; this difference affects processing costs.
After-sales service and spare parts supply cycles are also factored into the price, such as whether remote parameter adjustment or local engineer support is provided.
Highly customized equipment, such as changing bag sizes or adding multiple sealing structures, will also increase manufacturing time and price.
Price Differences Between Different Models
Based on common market quotes, small fully automatic liquid sachet packing machines are mostly priced between USD 2,500 and 6,000. These machines typically use a single-row forming structure, producing approximately 30-60 sachets per minute, suitable for small-batch dispensing of aqueous or low-viscosity liquids, such as beverage concentrates or sauces. Mid-range models are mostly priced between USD 6,500 and 14,000, commonly featuring a double or triple-row parallel operation structure, equipped with a servo film pulling system and an independent temperature-controlled sealing module, achieving a speed of 80-120 sachets per minute, suitable for factory environments with relatively stable production rhythms. High-end models are generally priced between USD 15,000 and 22,000+, employing a multi-row synchronous structure and a continuous feeding system. Some models include automatic deviation correction and online detection functions, suitable for production lines operating continuously for extended periods, such as large-volume filling tasks for sauces or viscous liquids.
Different Applications
The requirements for the configuration of Automatic Liquid Sachet Packing Machines vary significantly depending on the application scenario. In the food processing industry, materials like tomato sauce and honey have high viscosity, requiring equipment with heated hoppers or stirring systems to prevent material sedimentation during prolonged downtime. These configurations increase the overall machine price by approximately 15%–25%. In daily chemical product manufacturing, such as shampoo or shower gel packaging, the focus is on sealing stability and bag shape consistency, thus requiring photoelectric detection modules to monitor seal integrity. In chemical liquid packaging, highly corrosive liquids necessitate corrosion-resistant materials for contact parts and higher sealing ratings, impacting overall cost. Some beverage concentrate production lines opt for multi-row high-speed machines to match filling schedules. These machines need to operate synchronously with the upstream mixing tanks to prevent discontinuous feeding; different configuration combinations result in significant price differences.
When selecting an entire machine, the price of an Automatic Liquid Sachet Packing Machine is not the only indicator; matching material characteristics with production schedules is crucial. For small-scale production, a simple single-row machine is preferred; medium-sized factories often use double-row or triple-row structures to balance output and floor space; large production lines require multi-channel continuous operation to reduce downtime. In actual trial runs, the performance of filling speed and sealing parameters on different liquids often determines the final configuration. Considering expected output, liquid properties, and future expansion potential to determine the budget is more effective in avoiding later modification costs than simply comparing quotes.
